ROCKER 400 Vacuum Pump Zero air pollution, no costly maintenance: Rocker series vacuum pumps
work with a piston without the need for lubrication.
 
Prote™ overflow protection: Rocker series pumps have Prote™ filter cartridges that prevent the pump from negligently absorbing large amounts of liquid. These filters also filter out moisture and particulates, prolonging the life of the device.
 
Thermal protection device: All motors in the Rocker series pumps have a built-in thermal protection device that turns off the device when overheating and keeps it running when it cools down.
 
Applications: Filtration for microbiology, air sampling, vacuum filtration, suspended solids testing
