The Rocker Models 300, 300DC, 400, 410, 430, 800, 810, 801, 811 and Lafil 400 oil free laboratory vacuum pumps use piston pumps that require no lubricant, regular oil changes or other routine maintenance. The oil free design means that the pumps are cleaner in operation.
Rocker series pumps are equipped with the Prote™ filter cartridge that can prevent a large amount of liquid from being
sucked into the pump through negligence. The Prote™ cartridge can also filter particle and moisture to prolong the service life of the pump.
A direct drive motor eliminates the noise and complications of a belt drive and together with careful vibration lowering assembly results in a lower noise levels. The motor used in the Rocker series of pumps has a built-in thermal protection device that shuts off the pump automatically when overheated and then resumes working after it cools down.
Whatever the laboratory application, be it filtration, air sampling, suspended solids or another process in which a vacuum is required, the Rocker oil free vacuum pumps are ready to give dependable long term service.
