BOFA Replacement Bag Filter for Suction Unit

This Bag Filter is for the BOFA DustPRO Universal Extraction System

The pre-filter is designed as a barrier, to help capture the larger dust and particulate, helping to protect the HEPA filter from premature blocking.

BOFA offer a range of pre-filters, all designed for different applications and processes, depending on the amount of dust being extracted.

The efficiency of the pre-filter is directly related to the life of the HEPA in that the more particulates captured in it, the less can pass through and prematurely block the HEPA. Most pre-filters have an efficiency grading of F5 – F7*.
