The device is configured for lateral reinstatement with the Bowman 0.8 hp or 1.2 hp crossflow air motor. Optimum performance is reached with the 2.5 hp geared air motor, which reduces reinstatement time by 80 percent. The cutter can be disassembled and reassembled in 30 minutes and has only eight moving parts. All electric motors are isolated at the end of the cutter in a watertight chamber, eliminating water damage and allowing for easy access. The cutter is manufactured from temper-hardened stainless steel and bronze to cut tough liners, including UV-cured liners. 717/432-1403; www.bowmantool.com.

 

Joint seals
