About Stationary Vacuum SystemsSubstantial savings can be realized by installing a Dustontrol system.Following are some example installations;• All grinders and fi nishing tools in an FRP production facility are

equipped with suction casings and connected to a central extraction system. Capture of the dust at source contributes to an improved working environment, higher productivity - shorter clean-up, cleaner process and improved product quality.

• Cleaning of saws, mills, lathes and other process machines with a centralized system. More effi cient production, cleaner machines, faster production, effi cient lubrication use and a higher return on prompt scrap through more eff ective collection. Your people spend less time on tasks that do not add to the bottom lne

• Extraction of chips and lube directly at the source: Cleaner parts thoughout the production process, and a cleaner environment on the shop fl oor. Cleaner machines mean better functioning lube systems,

better function means cooler running tools. Cooler tools mean better parts and longer tool life.

• Fume extraction with extraction integrated welding guns.Reduced exposure to fume, healthier welders, higher productivity.

• Vacuum cleaning systems and air cleaning equipment in bakeries reduces airborne fl our dust that is dangerous to health and can cause asthma: Th e health and safety regulations are met and at the same time the workplace environment and overall effi ciency is improved. Fewer health problems from employees will aff ect insurance rates positively.

• Extraction/vacuum systems in pharmaceutical production for source extration in the process and for cleaning of production machinery and areas. To eliminate hazardous dusts generated during pharmaceutical production is a must from a health perspective as well as a product quality issue.

1 IntroductionTo attain the desired effi ciency and benefi ts with an extraction system, the system must be complete; from the suction casing to the vacuum producer to the control system. All the components of the system are equally important in implementing its functionality.

2 Vacuum ProducersTh e vacuum producer is the heart of the system. Here the vacuum is created that drives the system. In Dustcontrol extraction systems, the vacuum level is gene rally from 6–40 kPa.Our normal source extraction and vacuum cleaning systems use turbo-pumps. Th is device has an ideally suited characteristic capacity for this type of system. Vacuum level increases as more resistance is pre sented, an important quality in minimizing the possibility of blockages in the tubing system. For applications involving fume and light dust, such as paper, radial blowers are used. Th ese have larger air-fl ows and operate at a lower, relatively constant vacuum level.Our turbopumps and radial blowers have very high quality built-in silencing, see technical speci fi cations.

3 Filter UnitsAn extraction system should always be equipped with a fi lter unit. Dustcontrol fi lter units separate coarse material in the cyclone body of the unit and fi ne dust in an internal arrangement of conical pleated cartridge fi lters. Pleated fi lters have very high fi lter areas in relation to their physical size. Th e fi lter units therefore have high capacity while maintaining compact overall dimensions. Filters are cleaned with reverse pulse which results in very eff ective cleaning, long fi lter life and low maintenance.Normally the fi lter units are equipped with a plastic sack for collection of the extracted material but other types of discharge arrangements can also be installed.

4 Pre-SeparatorsPre-separators can be used in all applications where the extracted material is coarse or voluminous. Th ese can be placed in the actual workplace for separate handling or recovery of the extracted material, or centrally.Pre-separators separate material from the air fl ow using cyclonic action or with inertial separation. Inertial separators are generally confi gured as containers with the inlet and outlet in the same wall of the container. When the air fl ow changes direction abruptly, separation occurs for the particles with higher relative mass. When pre-separation is used to accommodate higher material volumes it is also important to consider the type of material discharge to be used. Dustcontrol off ers a range of diff erent standard options including; screw compaction, airlocks or container collection.

5 Tubing SystemTh e tubing system transports the material from the point of collection to the central unit. Dust is generally abrasive, some more than others,

The Complete System therefore the standard material thickness of the tubing system is 1.5 mm. Applications with fume and light dust use reinforced spiral duct. Stainless tubing systems and extra abrasion resistant fi ttings are available.Dustcontrol has a very compre hensive assortment of tubing fi ttings and installation hardware. Th is gives greater fl exibility in design and installation of our tubing systems. Our mechanical jointing system makes alterations and additions very easy to carry out. Cones, branch pipes and bends are manufactured in EPDM- and NBR- rubber. Th e components are hard-wearing and sound deadening.

6 Work Place EquipmentAn extraction system is sized for only those outlets which are to be used simultaneously. Th is is in order to maximize effi ciency and minimize the size of the central unit. All outlets must have some type of closure, either a fl ap valve or shutter. Th ese can be manually actuated, such as fl ap valves or manual shutter valves, or automatically controlled for actuation only when extraction is required.Th e Flexpipe can be used for fume extraction, high fl exibility and small diameter allow it to be placed very close to the fume source.Overhead suspension arrangements such as swing-arms and hose reels can increase the usefulness of the system, increase ergonomics and minimize potential trip hazards from hose left on the fl oor.When large volumes of material are to be introduced into the system, stainless fl oor funnels can be used from which the material is then extracted.

7 AccessoriesA hose must have many qualities, the foremost for the operator however is fl exibility. It should also be tough enough to withstand the abrasion created when transporting the extracted material. Hose selection should include consideration of abrasion, chemical and heat resistance as well as conductivity to static electricity. Dustcontrol has a comprehensive assortment of hose types, diameters and hose connections.Cleaning tools, suction casings and special nozzles are those compo-nents that are actually used to cap ture the dust. Th e design and eff ective ness of these will determine the effi ciency and acceptance of the entire system. Th is demands a varied and comp lete assortment of specially designed products. Dustcontrol has that. If a standard pro-duct does not exist, we have the capacity to design and manufacture it.

8 Control SystemsMotor starters and System Control Panels control the operation of the system, both operation of the vacuum producers and cleaning of the fi lter. A variety of other control functions can be installed as required. Even with a rather basic control system, intelligent features can be included to clear coarse material in the main tubing runs or control vacuum production and therefore energy consumption according to actual requirements.

Planning and Design of Extraction SystemsTh e following points must be considered and a clear defi nition must be developed before design of the system can be undertaken.

• Determine the function of the system – source extraction, cleaning or pneumatic transportation. In many cases it can be wise to equip the system for diff erent functions apart from the main function of the system, for example; cleaning.

• Choose the outlet confi guration. Determine for each outlet the type of extraction equipment required as well as the type of closure ( automatic or manual ). To determine this, a detailed study of the types of activities in each work place must be undertaken.Determine the number of outlets in simultaneous use. Th e system will be designed for a maximum number of users at any point in time. In larger systems, the number of simultaneous users in diff erent parts of the system should be determined.

• Decide the routing of the tubing runs and location of the central unit. Consider the degree of diffi culty for installation; ceiling height, wall and roof perforations, moving equipment into place, etc.

• Consider the type of material to be extracted, the degree of abrasion, risk for explosion and risk for clogging, etc.

• Determine the volume of material to be collected per unit time. Select the type of pre-separator and type of material handling for collected material. Material discharge etc, must be determined according to the customer requirement.

• Select the type of control system to be used, for example; programmable start – stop or work place start - stop.

• Determine electrical and compressed air supply requirements for the system. Indicate location of the requirement and assign responsibility for the supply and installation.

Tube SizingTh e tube dimensions are selected on the basis of maintaining the correct transportation velocity in all parts of the tubing system. It is necessary not only to consider the velocity in the main runs but also in all the branches of the tubing system. Th e tube diameter should be selected so that a velocity of > 20 m/s is maintained for particle transportation – for fume, a lower velocity of > 12 m/s is used.

As an exception in normal systems, we recommend that the smallest tube diameter be 76 mm, even if the minimum transportation velocity recommended is not maintained.

System DesignAlways try to maintain a star confi gu ration for the tubing system where the main runs are of more or less equal length leading to the central unit in the middle.A balancing of the system must be done to ensure that air-fl ows are suffi cient for proper extraction at all points in the system and that transportation velocities are maintained.In a system for fume extraction, a large main duct can distribute the system’s capacity. Any combination of outlets can be used. Conversely, in a system for the pneumatic transportation of heavy material, the transportation velocity must be maintained. In these systems, one open outlet per tubing run is the norm (usually 76 mm).

Th e system’s capacity is determined by the worst case – usually the maximum number of users with the highest air-fl ow collectively. If you are unable to determine which scenario gives the highest pressure loss, several calculations may need to be performed.

Pressure loss calculations for this type of system are infl uenced by a number of diff erent factors and exact calculations can be very complex. In general, the following calculation can be used. With material loadings greater than 1:1 (= 1,2 kg material per m³ air), a practical test should always be done. Calculate the pressure loss for clean air from the extraction point to the pre-separator according to the calculation on the previous page. Calculate the added pressure loss that the transported material will result in according to the following:Δpmaterial=Δp0x m1/(Q x 1,2) (kPa)where Q is air-fl ow in m³/hm1 is material fl ow in kg/h Calculate then the pressure loss for the remaining system (pre-separator to vacuum producer). Add this value together with the pressure loss value from the previous calcu lation. Add the safety factor to the sum of these.

Pneumatic Material TransportationTo transport larger volumes of coarse dust or other material requires a series of special considerations to minimise the possibility of clogs in the tubing system or problems discharging collected material.

• Th e system should be designed for transportation velocities from 20 – 25 m/s. Higher velocities result in increased wear. Ensure minimum transportation velocity is main tained in the tubing system (only one outlet in use per run).

• Select tools and accessories which allow suffi cient transport air into the system.

• Minimize the number of 90° bends. Never install two 90° bends closer together that 25 times the tube diameter.

• Select horizontal or vertical tubing runs. Avoid sloping runs where material ”corning” may occur. In sloping runs material will have a tendency to precipitate and run down against the direction of fl ow in the bottom of the tube.

• Select, hose, tubing and separator with consideration to abrasion.• Select material discharge with consideration to the consistency and

volume of material to be discharged.• Plan emptying intervals and routines (plastic bag or container).

Th e DC 11-Module is a complete central unit for source extraction and industrial cleaning. Th e unit can manage just about every kind of dust and chip you can imagine, and when properly equipped, your coolants and emulsions too.

With the DC 11-Module, we deliver a complete central unit from the factory, plug and play - easy to install. We tailor it exactly to your specifi c needs. Th is is possible due to an options based selection process. Th e DC 11-Module has been designed to produce more capacity/HP and service up to six normal extraction points or several cleaning outlets at a time. We’ve worked hard to get the standard sound level to just 65 dB(A). Need a HEPA fi lter? - Just select it as an optional extra.Th e discharge system can be chosen in accordance with the material to be handled; making it easy for your people to maintain their equipment. Th e DC 11-Module is also suitable for source extraction and general cleaning in smaller production areas. Note that the unit can connect to many extraction points, as long as the number of users does not exceed the maximum capacity. For energy saving and reliable remote activation of operation, the DC 11-Module is also available with the DC Green System. For futher information , see page 128.

Optimized Stand-Alone UnitTh e design of a source extraction system is always based on the specifi c need at each work place. It is then possible to design and install a central unit for several, or many, extraction points. Alternatively, maybe a stand-alone unit for a particular area is the best choice. Th e advantage with stand-alone solutions is that you attain cleaner production one step at a time - as production requires it and as budget allows it. Th e DC 11-Module becomes part of the work cell or production machine and can be part of the fl exibility of modern lean manufacturing and fast change-overs from part to part.Th e DC 11-Module is developed to fulfi l the demands of a local solution.

HEPA FiltersTh e fi ne fi lter separates a large quantity of the fi ne dust, but has a limited effi ciency on the smallest particulate. In order to capture this particulate, the unit should be equipped with a HEPA fi lter. We always recommend that a HEPA fi lter be used when the system air is returned to the plant environment. With designated or hazardous dust we recommend the use of a HEPA fi lter even if the system air is to be vented out of the plant. (Note: Always be aware of and comply with local regulations.)

Safe ChangeWhen dealing with designated or hazardous dust, the fi lters (fi ne and HEPA fi lter), should be able to be changed without exposure to the personnel or plant environment. Th e same applies for changing the bags. By choosing the safechange solution, which includes the HEPA fi lter, a system is designed that keeps negative pressure in the cyclone during this operation. By putting plastic bags over the fi lters before they are changed, protection against dust can be maintained.

Control PanelTh e electrical function is built into the machine. Th e unit is started manually with a start button, automatically when any of the extraction points are opened and micro-switches are used or by clock control. Filter cleaning is automatic after shutdown of the vacuum. With the DC Green System option you get on-demand control for saving energy, see page 128. You can also choose if the unit should be a fi xed installation or mobile and be delivered with a Euro connection (5.5/7.5 kW).

Vacuum ProducerTh e vacuum producer is a direct driven turbo pump. It is highly durable and has minimal service requirements. Th e characteristic of this type of vacuum producer makes it excellent for use with a VSD. With the frequency converter option the performance capacity will be optimised.

Filter UnitTh e fi lter unit separates the larger particles in the cyclone and the fi ner dust in the pleated conical fi lter. Th e fi lter is cleaned very eff ectively with reverse pulse. Normally, compressed air is used for fi lter cleaning, but manual fi lter cleaning that does not require compressed air can be chosen as an alternative. Th e fi lter unit separates everything from fi ne dust to chips and fl uids.

Outlet/ExhaustFor fi xed installed extraction systems it is always recommended to exhaust the air out of the building if a HEPA is not used. In doing that, all residual particulate and any gases extracted are expelled from the building. With the help of a HEPA fi lter, almost all the particles can be eliminated. In a large plant, exhausting to atmosphere can sometimes be diffi cult. In these cases exhaust directly at the unit can be considered. Extra duct work and optional silencing is available to suit the installation.

Discharge of materialDischarge of dust, fl uids and heavy material is done under the cyclone. A number of diff erent solutions can be chosen. Th e most common is plastic bag or container. Containers are available with a variety of volumes. Containers can be equipped with wheels, internal plastic bag, level glass and a drain tap for lubricants.

Mobile UnitTh e DC 11-Module is designed with a pallet format chassis so it can easily be moved with a fork truck or pallet jack. By choosing to equip the unit with wheels and handle, a mobile unit is created that even with its large size and weight, is possible to move easily by hand on the production fl oor. Th ere is also the possibility to create a semi-mobile unit where the unit is confi gured as a portable but docked to an installed tubing system. When it is required elsewhere, un-dock it, and wheel it away.
