Rocker Vacuum Pumps

Oil-free vacuum pumps are piston powered, so they do not pollute the air and require minimal maintenance.
Quiet, low-vibration units keep disturbances to a minimum.
Built-in thermal protector automatically shuts off pump if it overheats and then restarts it once the unit is cool.
Inlet filter traps particles and removes moisture, prolonging pump life.
International CE and CSA certification.
Applications include filtration for air sampling, microbiology, suspended solid test, vacuum oven, thermal desorption (TD) tubes, sampling bags (regulator recommended for TD tubes and sampling bags), and general use. (Not intended to evacuate air canisters.)
Two-year pump warranty.
