Bag Prefilter
|
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.
