Research Focus Low Pressure Resistance and High Efficiency

HEPA Filters

ASHRAE Standard 52.2 – MERV (Minimum Efficiency Reporting Value) 17.

Minimum 99.97% efficiency at 0.30 microns particle size.

Clean Rooms, Hospitals and Hazardous Material Areas.

Commercial Office Facilities and Institutional Buildings.

LEAF(Low Energy Air Filtration)

New super-high-surface-area winged fiber media.

Bicomponent - polypropylene and polylactic acid spunbond nonwoven fabric with charge stabilizers.

Patents have been approved and issued.

65% less pressure resistance and 50% greater dust holding capacity.

Important Considerations

Capture EfficiencyInitial Pressure Drop (and Final Pressure

Drop)Dust Holding Capacity

– Indicates the amount of debris the filter media will trap and hold before the flow is restricted such that media must be changed out in the filter press.
