All parts in contact with pumped media are made of aluminum and selected plastics (PTFE diaphragms and valves). They enable a wide range of applications for non-corrosive gases. The inlet and outlet connections of the ME 4R NT are equipped with regulator valves for vacuum and overpressure, respectively. Both the compression pressure and vacuum level can be adjusted. Inlet vacuum level and outlet pressure are indicated by manometers. This one-stage diaphragm pump is an excellent choice for continuous, oil-free pumping and evacuation of non-corrosive gases and also for compression. Typical applications are vacuum ovens, pressure and vacuum filtrations and generation of compressed, absolutely oil-free air. Inlet- and outlet pressure can be adjusted continuously using the regulator valves. The manometers on inlet- and outlet side enable easy setting of the desired vacuum and pressure levels.INCLUDED: The VACUUBRAND ME 4R NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
