High Efficiency Filter Without Separator (or HEPA Filter Without Separator)

Product features

Compact structure, easy installation and replacement The Puricel II frame is made of aluminum extruded profile, and the imported phosphorus-free polyurethane adhesive is used to seal the waterproof and flame-retardant fiberglass filter element which is spaced by hot melt adhesive, supplemented by the surface protective mesh, sealing gasket and other components. It features a compact structure, small and light, easy installation and replacement. Comprehensive leak testing to ensure no leaks The industry's advanced environmental-friendly water-based aerosol leak detection platform is used for testing without secondary pollution, to ensure that each piece of filter is leak-free. Testing efficiency according to EN1822 According to EN1822 standard, the United States PMS laser particle counter and PSL test particles are used to test the efficiency of the filter using the most penetrating particle size (MPPS) method to ensure that the filter efficiency meets requirements.

Separator-free structure, with low resistance and good energy saving

The specially designed hot melt adhesive is used to separate the HEPA filter paper to ensure the same and reasonable spacing between the filter paper, which can make full use of the filter paper to achieve uniform air speed and low resistance.

Strictly selected materials, with very low chemical volatilization

All components are made of very low chemical volatile materials to meet the requirements of conventional cleanrooms for air filtration equipment.

Non-continuous spraying technology with low resistance; "V" shaped channel, with low resistance and long service life;

automatic staging to flexibly adjust pleat height and width for demand.

Specifications

Leak test - To ensure that there are no leaks on the filter, it must be scanned and tested. Filters that have passed the general leak test may still have some leaks, which can be found by scan test and repaired before leaving the factory. A multi-functional ethanol aerosol that does not remain on the filter material is used for testing.

Wedge-shaped pleated layer design to prevent damage to the filter media

PuriCel I separator box HEPA filter folds the filter media on both sides and forms two indentations at the bends, which can make the filter media form wedge-shaped box pleated layers at the end of the separator, thus preventing the filter media from breaking and prolonging the service life of the filter. The corrugated aluminum separators precisely maintain the distance between pleated layers, and the edges of the separators roll over to prevent damage to the filter media, maximizing the use of the filter media with minimal resistance.

Ultra-fine fiberglass high-density filter paper, featuring water resistance and flame retardancy

Selected high-quality ultra-fine fiberglass filter media is used, with high density. The filter media is waterproof and flame retardant.

100% leak-free

The polyurethane adhesive completely seals the filter media within the frame and penetrates between the filter media to prevent voids and completely seal the channels where side leaks may occur, such as the edges of the filter media and the separator.
