PneuLuber air-operated grease gun is fully automatic and dispenses one tube of grease in less than 1 min. It operates in pressures to 6000 psi and works on small portable compressors by using 40 to 60 psi at 3.5 cfm. Dual-piston gear motor provides constant torque. Variable speed trigger controls flow and eliminates waste and contamination. Pressure relief valve identifies blocked bearings, lubrication line, or fittings, and lets excess grease flow back into barrel.
