ULVAC Single-phase 100V Diaphragm type dry vacuum pump Overall width 181mm DA-81S 1 unit

Catalogue number: DA-81S Features: *A vacuum pump that uses the reciprocating motion of a thin rubber membrane (diaphragm) to evacuate air. *A dry vacuum pump that does not use oil or water in the gas contact parts. A thermal protector is built in for safety. *Simple structure makes maintenance easy. Applications: *Suction transport, suction fixation, vacuum tweezers. *Analytical equipment, physicochemical equipment. *Semiconductor inspection equipment. *Device assembly. *Automatic machinery, packaging machines. Specifications: ●Exhaust speed (L/min) 50/60Hz: 75/85 ●Attained pressure (Pa): 13.3 x 10 [to the power of 3] ●Intake port diameter (mm): 12 ●Power supply (V): Single phase 100 ●Overall width (mm): 181 ●Overall length (mm): 336.5 ●Overall height (mm): 217 ●Power cord length (m): 1.8 ●Can be customized to accommodate different voltages from a single unit (excluding DAL-181D/DAL-361S) ●For low speed and low pressure Caution: ●When restarting the pump after it has stopped, it may not restart if there is a vacuum inside the pump. The pump will restart if the pressure inside the pump is returned to atmospheric pressure. ●The "DA-41D" and "DA-81S" are equipped with a balance port. This balances the pressure on the first and second stages of the pump chamber, enabling it to start up under vacuum.
