Category: HEPA Filter

HEPA Filters (High Efficiency Particulate Air) are used either as stand alone when the dust loading is very low, or preferably on the exhaust side of a bagfilter, cartridge filter or cyclone where the gas stream has already been filtered. They can be used as an inlet or outlet guard filter.

The HEPA element can be single stage or multi-staged design so that the correct collection efficiency at each stage is achieved. The materials of construction range from aluminium through to mild steel and stainless steel. They can also be supplied with a safe change option which reduces operator exposure when the HEPA elements are being replaced.

The range of HEPA elements are vast and are selected by Pennaire to suit the application. The efficiencies range from a roughing pre-filter (G3-G5) to a high efficiency filter (H10-H14), or a combination of both in multi-stage arrangements.
