The power supply is 12 Vdc and the engine develops a strength of 65 W, guaranteeing a capacity of 53 L/min with a maximum of 2.5 bar. It reaches a vacuum of -760 mm Hg [-29.92 in Hg]. These features render it suitable for achieving a very powerful vacuum system, comparable to those of hospitals. It has a reliable and robust construction. On the skeleton of the pump there are M 6 threaded holes for the attaching of the pump. No maintenance required. Threaded outlet fittings.
