Rigid HEPA Filter With Aluminum Separator Galvanized Steel Frame Clean Room

The Rigid surface HEPA filter are special design for clean rooms,

Aluminum alloy separator can be used in high moist and high temp situations;

Paper separator can be used in low moist environments;

Descriptions of extended rigid surface HEPA filter with separator;

1. Folded extended filter media, provide large filter area increase air flow rate at the same time reduce air pressure drop;

2. Specially design filter media, can capture fine dust with very good dust holding capability;

3. HEPA filter efficiency reach to 95%, 99.5%, 99.99% @ 0.3um ( MPPS );

4. Filter efficiency range H10, H11, H12, H13, H14 ( EN:1822 Standard ); or F7, F8, F9 ( EN:779 )

5. Aluminum alloy separator can live longer in moist, strong acid, alkali situations;

6. Polyurethane sealant be installed in every slot, make sure no air leakage;

7. Neoprene gasket, endless design thickness 5mm, prevent air bypass;

8. Metal face guard to be added in both air inlet and outlet side, protect filter media from damage when handle the HEPA filters;

9. Filter frame option: galvanized steel sheet, SUS201, SUS304, aluminum board available;

SUS304 frame can be used in particular situations like High Temp and High Corrosion.

10. Various construction design, box, flange, double flange for your choice;

The relationship between air velocity with filter efficiency;

HEPA filter is the most important of cleanroom, the main function for HEPA filter is to capture fine dust size from 0.3 to 0.5 um; Normally, when air velocity raised, the efficiency declined; because the fine dust spend less time to stay at the filter media, so there are less risk to be captured; As experience said, when air velocity become half, the efficiency raise to order of magnitudes;

How to choose HEPA filters ? At first you must understand the air flow rate of HEPA filter,

For examples, 610*610*292 HEPA filter with separator, it`s 2000 CBM per hour for standard design; 3000 CBM per hour for high air flow design;

Quality control for rigid HEPA filters
