3M™ Versaflo™ Pre-filter, TR-6600 (Pack of 10)

Pre-filter can extend the service life of the particulate element of TR-600 series filters by capturing large particles that may otherwise clog the filter. Frequent pre-filter changeout may help optimise system performance.

The TR-6600 prefilter can extend the service life of the particulate (HE) element of TR-600 series filters and cartridges by capturing large particles that may otherwise clog the HE filter. Frequent prefilter changeout may help optimize PAPR system performance. The TR-6600 prefilter must be installed and used according the the User Instructions. Use of the TR-6600 may reduce PAPR operating costs by extending the service life of the main filter/cartridge. The TR-6600 is maintenance free and should be discarded when loaded or damaged.
