The Bag Prefilter is a disposable filter element specifically designed to reduce dust loading on the M98 HEPA filter. It is constructed of a two-ply, non-woven fabric for high dust capacities at low-pressure drops.
The Bag Prefilter installs securely inside the CBR filter housing without tools or clamps and is available in five (5) lengths. The prefilter does not require a critical seal and can be replaced quickly and easily without testing.
Typical service life of the Bag Prefilter is six months. It is compatible with the OpenAire™ Flow Regulator for dust removal during ventilation startup and balancing.
