When air flow volume is reduced for25%, expected service life of Hepa filter doubles.Service life can be considerably increased withinstallation of pre-filter. The dirtiness of the filteris controlled by the means of differentialmanometer fitted withU-tube (fig. 4).Connections for plastic tubes are fitted on AKF housing.The initial pressure drop is specified in table 5.When the pressure drop has reached double its initial value, it is recommended to replace theHepa filter. When replacing the AFV-8 filter,remove diffuser and screws on the holding barand then remove the bar together with used filter.When installing the new filter use the aboveinstructions in opposite order. The sit tightness is to be tested according to DIN 1946 standard,chapter 4. The permeability at the test pressure of 2000 Pa should not exceed the values stated in standard (Table 6). The checking is carried out with sit-tightnessmeasuring device (fig. 5).Ordering example:Designation: AFV-8/RS3/OD-9 RAL 9010Connection type: circular side entryspigot RSSize: 3-with filter 610 x 610 x 78 H13 class (99,95 %)Air flow volume: 1200 m3/hDiffuser: OD-9 RAL 9010Pcs: 12On request it is possible to produce also AFV-8units for other sizes of HEPA filters.Manometers have to be ordered separately.Example of manometer order:Manometer Magnehelic 0-750 Pa, fitted on thehousing.Filter Hepa FlowAllowed.unit size filter (m3/h) permeability (%)1 305 x 305 x 150 290 2,92A 457 x 457 x 78 660 6,62B 457 x 457 x 150 660 6,63 610 x 610 x 78 1200 12,04 610 x 610 x 150 1200 12,05 610 x 610 x 292 2400 30,0Ordering keyTable 6Fig. 4CEILING HEPA FILTER UNITSAFV-8TECHNICAL DATAsize 1 ... 8 (only RAL 9010)R manualB electric motorZL-2for filter 305 x 305 x 150for filter 457 x 457 x 78for filter 457 x 457 x 150for filter 610 x 610 x 78for filter 610 x 610 x 150for filter 610 x 610 x 292Circular side entry spigot *Circular top entry spigot *Rectangular side entry spigot *Diffuser KD-1AKD-1KD-6OD-8OD-9Damper controlShut-offdamperHepa1filter 2Aunit 2Bsize 345Connection RSRVKS* The AFV-8 version with the shut-off damper ZL-2 is only availible with theRS and RV versions.Hepa filter: Size and filter class is to be specified independently.It is recommended that a separate manometer is used for each filter unit.

They are designed to be built-into the false ceilings of OP rooms and intensive care premises andto ensure the laminar flow of the absolute clean air into the target zone. The aim of the above device is to reduce the possibility of infection in OProoms being caused by germs which are due to different causes constantlypresent in the premises and surroundings.Description:The preparation of air for the OP theatre is accomplished with separate airconditioning system, capable of rough and fine air-filtering according to DIN 24185.The filtered supply air is distributed to the absolute filter on the DPS plenum box.The air is discharged from the pressure chamber into the OP theatre via theperforated ceiling plates. The temperature of the discharged air is to be 1 to 3 Clower then the average room temperature. Two thirds of the air current should be ledout of the room via the floor and one third via the ceiling. The air current which isbeing discharged from the DPS flows over the entire area under the ceiling thuspreventing the surrounding air from penetrating within the operation area (fig. 1).Base material of pressure chambers and perforated plates:steel sheet painted with epoxy dusty paint RAL 9010, resistant to disinfectantsCeilings (except the size of 2000x1000) are composed of two parts, which arebolt together at the assembly point.In the assembly operations the connectionsare additionally packed with the acrylic putty, which is attached to the ceiling. At the consumer's request the ceiling contains a transition for the operatinglight of the dimensions 300 x 300 mm. In that case a blind plate and a platewith a round opening of 150 mm.Perforated plates (from inside the ceiling) are covered with a PPI-20 blackfoam for a more uniform distribution of air. The delivered foam is packed in afoil in order to protect it from dirt and damage.Fixation of the perforated plates is on the one hand carried out with the help ofhinges and on the other hand with the help of locks.The ceiling is fitted with the hepa filters 610x305x292, which belong to the classH13 or H14 and have been tested according to the DIN 24 185, which means thatparts in diameter of 0.3m are removed 99,95% and 99,995% respectively. Theyare fitted into the side connection on the longer side of the ceiling. The dimensionsof the connection duct and the number of filters are given in the table. The insideof the ceiling is fitted with the filter pressure drop measurement connections (thedifference between the pressure in front of and behind the filter, which serves tocontrol the dirtiness of the filter) and with the DOP or PAO test connection.With the nominal flow rate of air, given in the table, the initial pressure drop is 250 Pa.At a filter load with larger or smaller flow rates than the nominal the pressure drop increases and decreases respectively, which is shown in the diagram. Leak-tightness of hepa filter at the sealing frame is in accordance with the DIN 1946 standard, Chapter 4. When changing filtersone has to check the leak-tightness of the hinges.The ceiling, filter body, filters, PPI-20 foam and the assembly material aredelivered separately.The assembly of ceilings to the concrete ceiling is carried out with thethreaded bars and inners for the concrete.Hepa filter replacement:During the operation the permeability of the Hepa filter is decreased and thedifferential pressure increases. The permeability-loss rate is measured withdifferential manometer via the tubes fitted in front and after the filter. When thepressure drop has reached double its initial value, it is recommended toreplace the Hepa filter. When replacing absolute filters, the first row of faceplates has to be removed.Fig. 1PERFORATED SUPPLY CEILING DPSWith transition for the light and three filtersWithout the transition for the light and two filters434PERFORATED SUPPLY CEILING DPS TECHNICAL DATA 500400300250200100p (Pa)500 1000 1500 2000 2500 3000 3500 4000 4500 5000Q (m3/h)a r t l i f 2 r e t l i f 13 filtri4 filtriPressure drop diagram according to no. of filters 305x610x292 Ordering example:Supply perforated ceiling: DPS 5 x 4Number of plates / longitudinal: N = 5Number of plates / transversal: n = 4Ceiling has a sparing for installation of OP lights.It is possible, in case of special demand,to produce DPS in special sizes and for optional air flow volume.On the customers request we produce DPS ceil-ing made of stainless steel.N ...

It is intended to be built into a sus-pended ceiling in operating rooms and intensive care facilities.Description:The basis of the ceiling is a standard DPS perforated ventilation ceiling whosepanels are replaced with synthetic textile affixed to aluminum or stainless steelframes. The ceiling and filter housing may be either stainless steel or paintedzinc-plated panels.The synthetic textile allows laminar flow, because the tight weave of the fibersprevents turbulent flow from forming on the surface. The polyester textileadheres to DIN 4799 standards for the hygienic minimum for operating rooms.It has also all the necessary certificates for use in operating rooms, and it hashigh resistance to aggressive disinfectants. The synthetic textile may be single-layer or double-layer. The second layer allows the air to be evenly distributedacross the entire surface before it enters the room.Ceilings are made of one, two or four parts, depending on size. All elementsare screwed together at the installation site. Joints are additionally sealed withacrylic lute.At the customers request, the ceiling might be worked out with a transition foran operation lamp with dimensions of 300 x 300 mm. In this case a plate witha round opening for the lamp is attached.Fastening of the synthetic mask is done by special screws that are fixedmanually, without special tools.Class H13 and H14 Hepa filters, sized 610x305x292, belonging to and testedaccording to DIN 24-185 (meaning that particles with a diameter of 0.3m areremoved at 99.95% and 99.995% rates respectively) are built into the ceiling.They are built in the connections from the side or from the top. Dimensions ofthe connecting channels and the number of filters are given in the table.Connection is possible from the side or from the top, depending on thecustomers requirements. Inside the ceiling, connectors are built for measuringthe pressure drop on filters (the difference between the pressure before andafter the filter, indicating how dirty the filter is), as well as a connection forDOP (PAO) test.When filters are loaded with flow volumes greater or lower than nominal, thepressure drop increases or decreases as shown on the diagram.

Loosen the grille facescrew and simply withdraw the grille face from theinstallation frame.With the LN-2/Filter variant, withdraw the filterinsert from the frame and replace it by a newinsert.Nominal Filter Recom. dimension dimension flow rateB H B x H Q325 225 282 x 182 270425 225 382 x 182 380525 225 482 x 182 500425 325 382 x 282 600525 325 482 x 282 750625 325 582 x 282 900Nominal Free Recom. dimension area flow rateB H B1 H1 B2 H2 Q325 225 285 185 377 277 270425 225 385 185 477 277 380525 225 485 185 577 277 500425 325 385 285 477 377 600525 325 485 285 577 377 750625 325 585 285 677 377 900filter quality (G4 or F5)adjustment insertvisible screw fixinghidden screw fixingOrdering key:G4FVSInstallation:FLUFF SEPARATOR LN-2440B2/H235,532B/HB1/H1 333233 33 H13333B1B/HB1/H1 3332FR / V / F5 B x HF...InoxRAL9010Filter grilleApplication:Grilles with a filter are intended to be built in thewalls of rooms which require cleaner air (computercentres, libraries, clean rooms, etc,). Primarily usedfor exhaust air from the room.Description:Grilles are made of stainless (polish) sheet metal.The installed filter is of G2, G3, G4 or of F5quality.Dimensions:Standard dimensions of louvres are 225 x 75 mmto 1125 x 525. The depth of the grilles is 35 mm.Installation:Grilles may be fixed with visible screws (Vmarking, screws on the grille frame) or hiddeninto the installation frame (marking 2, grille isfastened on the installation frame with the lock onthe internal side of the grille. Installation frameshall be fixed on the wall before the installation ofthe grille.)Filter replacement:Due to the dirtiness of a filter, the pressure drop ona louvre gradually increases, therefore it isnecessary to replace the filter. The replacement of afilter is quick and simple. Lock may be used toopen the grille and replace dirty filter with the newone. The mask is then closed by means of a lock.Ordering key:filter quality (G2, G3, G4 or F5)visible screw fixinghidden attachmentB H B1 B2 H1 H2225 198 222325 298 322425 225 398 422 198 222525 498 522625 598 622325 298 322425 325 398 422 298 322525 498 522625 598 622425 398 422525 425 498 522 398 422625 598 622525 525 498 522 498 522625 598 622625 625 598 622 598 622Installation:1. by screws (designation V)2. onto the installation frame (designation 2)Dimensions:F5V2Nominal Filter Recom. dimension dimension flow rateB H B x H A Q325 225 283 x 183 0.05178 450425 225 383 x 183 0.07009 650525 225 483 x 183 0.08839 800425 325 383 x 283 0.10839 1000525 325 483 x 283 0.13669 1200625 325 583 x 283 0.16499 1500FILTER GRILLE FR441Example:Q=200 m3/hFilter G4FR/298x198Calculation of air flow per m2 of filter:2.
