Wob-L Piston Pressure Vacuum Pumps
Welch Wob-L Piston Pressure Vacuum Pumps offer piston performance and are ideally suited for vacuum/pressure filtration. They are durable and built for continuous duty producing pressure to 100 psig and vacuum to 27.3 in Hg.
Service life is extended with the use of treated aluminum and stainless steel wetted parts for corrosion resistance. A moisture trap keeps water from accidentally being drawn into the unit. A muffler suppresses running noise.
The motor is thermally protected. Regulators and gauges make it easy to meet your vacuum and pressure requirements. The oil-free system delivers clean air. A carrying handle, suction cup feet, line cord and on/off switch are included.
