With precise construction and quality moving parts, the noise level is only ~ 50 dB - the lowest among equivalent products! The pump not only keeps the laboratory quiet, but also protects the operator from noise disturbances. 

The Rocker 300 is next to maintenance-free because of the oil-free design. The Rocker 300 comes with guaranteed operation of two-years or 3000 working hours of free service parts (excluding the moisture filter)! 

APPLICATIONS:

• Liquid filtration
• Microbiology
• Suspended solid
• Air sampling
• Stack gas
• Ambient air
• Vacuum oven
• Fume suction

The Rocker 300 is equipped with a 1/8 hp motor and provides a maximum 20 lpm (110V/60Hz)... 17 lpm (220V/50Hz) of free air displacement and 650 mm Hg of maximum vacuum. It also contains one moisture trap/vacuum regulator for filtrating particles and moisture from the inlet air and features adjustment of the vacuum level. 

With its light weight, the Rocker 300 is not only suitable for laboratory liquid filtration, but also perfect for stack or ambient gas sampling. 

To enable the pressure function, a Conversion Kit (P/N 167320-30) is required for the simple, time-minimal conversion from a vacuum pump to a compressor.

• No air pollution, maintenance free
  Rocker series pumps are driven by Piston, no need for lubricant, regular oil changes and maintenance; with no oil pollution.
• Quiet and low vibration
  Driven direct by motor with no additional belt-driven transmission; the quality vibration-proof assembly makes Rokcer series run at the lowest noise level among all other equivalent pumps.
• Prote™ overflow protection
  Rocker series pumps are equipped with Prote™ filter cartridge which can prevent a large amount of liquid from being sucked into the pump by negligence. It can also lter particle and moisture to prolong the service life of pump.
• Thermal protection device
  Every motor of Rocker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
• Two-Year Warranty
