Low Noise Laboratory Vacuum Pump

摘要

New Star Environmental (USA) introduces their piston-powered oil-free Rocker 300 Laboratory Vacuum Pump that can provide vacuum and pressure in just one unit. 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. It comes with a guaranteed operation of two years or 3000 working hours of free service parts (excluding the moisture filter). 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.
