Leading the world with innovative products

Control Factors Inc has been a Legacy distributor of FSI products since 1984 and provides quality filter products from Filter Specialists, Inc. (FSI.)  Since the announcement by PALL that they are no longer supporting and have discontinued the entire FSI product line. We have been working with our suppliers to provide our customers with an EXACT replacement of the popular FSPN-40 & FSPN-85 bag filter housings, including an In-Line (Style#1) configuration option. We are still able to support and provide spare parts for your existing housings and filter bags with the Poly Snap fit Top with standard felt and extended life nominal media and absolute rated bag filters as well.

Please inquire about our current inventory of FSI replacement Filter Housings. You can find our current updated drawings for direct replacement of FSPN style housings.
