SUNDSTROM SR221 - Pre Filter Pack of 5

The Sundstrom SR221 Pre-Filter is designed to protect main filters against early clogging from coarse particles, helping extend the service life of Sundstrom gas and particle filters. This pre-filter is easy to use, fits securely into the pre-filter holder, and is then snapped onto the main filter.

The SR221 Pre-Filter is designed to extend the life of your main filters by capturing coarse particles before they reach the primary layer. It is fully compatible with the SR 510 P3 R and SR 710 P3 R particle filters, as well as the SR 299-2 ABEK1-Hg-P3 R and SR 599 A1BE2K1-Hg-P3 R combined filters. For maximum versatility, the SR221 can be used with all Sundstrom non-threaded gas and particle filters, making it a universal pre-filter solution across the entire Sundstrom system.
