3M 37354 Versaflo Particulate Pre-Filter for TR-600 Series Purifying Respirator

The TR 6600 pre-filter 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 pre-filter change out may help optimize PAPR system performance. The TR 6600 pre-filter must be installed and used according 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.

Features:

• May reduce operating costs by extending the life of TR-6000 Series filters and cartridges
• Easy-to-use due to simple maintenance-free design
• Flexible application because TR-6600 may be used with TR-662 spark arrestor
