After Filter Assembly From Below - ABS Blast

ABS Blast offers several dust collector accessories as optional equipment including an after-filter assembly.

The primary intent of the after-filter is to protect against dust being blown into the environment in the event of a leakage of the primary filters. The ASHRAE-95 (i.e. – 95% efficient) filter is the most commonly used after-filter for this type of protection.

In applications dealing with hazardous dust conditions or when particles must be kept to a minimum, a more efficient filter may be used.  A HEPA after filter is used when the filtration of the dust must be 99.97% down to a particle size of .3 microns.
