Daymat is equipped with a state of the art fabrication plant including plasma cutters, coil lines and bending machinery integrated with fully automated manufacturing software.

Approved construction drawings are directly uploaded to the Vulcan control and fabrication module using the Cam duct software protocol. Cam duct files are transferred to the fabrication systems where the software extracts the spatial parameters of the drawing and transposes them into the Vulcan fabrication language. The Vulcan software initiates production by commanding the coil line, plasma cutter and “nests” the data within the sheet metal and insulation to minimize waste and maximize production efficiency and together with the use of Daymat’ s unique barcode tracking system, every item to be manufactured is barcoded, scanned and checked through the various stages of the production process.

Our objective is to ensure the protection of all persons from personal injury or sickness arising from hazards at the place of work and to implement procedures to ensure maximum results from our efforts.

We regularly ensure that staff and workers keep pace with the latest professional standards and practices by taking courses to maintain and improve their levels of knowledge and competence.

Slide a Drive slip into the channel on the side of the duct. Repeat on opposite side.

Slide a S-slip onto the upper and lower end of the first length of duct.S-slips are used to connect two lengths of duct together.

Connect the second length of duct to the first by sliding its upper and lower ends into the S-slips.

Align the Drive slip so that its ends extend beyond the duct. Using a hammer, bend its ends so that they lay flat against the duct. Repeat on opposite side.

Blades number, type and operation

Blade Type

Triple Vee Profile blades are formed from a single thickness galvanized or stainless steel, incorporating three longitudinal V-Type grooves running the full length of the blade to increase strength. This blade is designed for low to medium, velocity and pressure applications. See the below details.

DVCD’S are designed with two types of Blade movements, based on the operation requirement

PARALLEL BLADES

Parallel Blades requires the damper blades to rotate in the same direction, parallel to one another. Parallel blades more suitable to low-pressure zone control systems. Parallel blades rapidly increases the flow when damper begins to open.

OPPOSED BLADES

In this blade movements, adjacent damper blades rotate opposite one another. Opposed blade configuration is typically used on dampers that modulate airflow. Opposed blades gives slow increase in the flow when damper begins to open.

The sand trap louvre is used as pre-filter for the protection of air conditioning plants in areas exposed to extreme levels of industrial pollution. It has a degree of separation of sand and large dust particles, even in cases of high dust concentrations. The vertically arranged sections and holes for sand drainage ensure the sand trap louvre is self cleaning and maintenance-free. The sand trap louvre is designed to separate large particles at low air velocities, thus avoiding excessive dust loading on conventional plant filters. It is not intended as a substitute for conventional supply air filtration plant.

There are two models from Sand Trap Louver : 1 - Daymat Sand Trap Louver DSTL .2- Daymat Sand Trap Louver with Removable Tray and Filter DSTL-RTF

Daymat Sand Trap Louver (DSTL)

Standard and Features:

• Frame : Gauge 16 from formed galvanized steel sheet.• Blade : Gauge 16 from formed galvanized steel sheet.• Holes : Drain holes of diameter 20 mm are provided in two rows at the

bottom of the louver for emptying filtered sand and dust .• Screen : Galvanized bird screen 12 x 12 x 1 mm fixed behind the blades.• Minimum Size : 150 x 150 mm.• Maximum Size : 2000 x 2000 mm.• Over 2000 x 2000 mm multiple section can be combined to provide any

combination of overall width or height.• Composed two sets of inverted U-channels mounted vertically on two

opposite rows.• Fixed with a removable washable extruded aluminum filter with aluminum

mesh as the filter media.• Can be manufactured from G.I or S.S as option .

Daymat Back Draft Damper (DBDD)

Description

Back draft dampers have been specifically designed for use in air conditioning and Ventilation system, these dampers are air operated and are used for air intake and exhaust, and are also used for pressure relief.Non return / Gravity / Back draft dampers either be operated by gravity ( where pressure or velocity opens and closes the damper ) or be motorized to open and close when required. These dampers are composed of a set of horizontally mounted blades, they are normally closed and free to rotate about the horizontal axis. The blades are manufactured from light weight aluminum sheet. Frame is manufactured from high quality aluminum as well as from galvanized steel.

• The casing frame is fully sealed robust and rigid assembly formed out of best quality aluminium sheets / galvanized sheet steel of 1mm thickness.

• Frame size: 125mm depth and standard flange height of 25mm.• Fully sealed low leakage blades are formed out of high quality light weight

aluminum sheets of 0.6mm thickness.• The bearing are made of PVC/Nylon to give smooth and rattle free operation

with 10 mm aluminum rod .• The blades are fitted with galvanized steel connecting spindle to main casing

/ frame for rigid and strong construction for rattle free and smooth operation due to variable air pressure.

• Blades seals: 20 mm x 20 mm aluminium angle.• A galvanized / aluminium angle is fitted internally to main frame to avoid

over movement of blades.• Structure is available with flanged edges and are supplied un drilled as

standard.

• System velocity and back pressure requirements.• Mounting orientation and air flow direction.• Mounting configuration ( Inserted into duct / opening or flange mount )• Damper operation ( Gravity or Motorized )

• Blades open fully or to any angle depending on the air velocity. • Blades stay in position of opening without fluctuating when there is constant

air flow. • Blades close quietly when the air flows stops.
