Vacuum Pump, Piston-Powered, 37 L/pm, 110V/1PH/60Hz

91-3970-07Vacuum/Pressure Pump, Piston-Powered, Oil-Free, maximum 37 L/min



Rocker 400 Laboratory Vacuum Pump 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 400 is next to maintenance-free because of the oil-free design. The Rocker 400 comes with guaranteed operation of two-years or 3000 working hours of free service parts (excluding the moisture filter)!

The Rocker 400 is equipped with a 1/6 hp motor and provides maximum 37 lpm (110V/60Hz)... 34 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 400 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 167420-30) is required for the simple, time-minimal conversion from a vacuum pump to a compressor.
