Oliefri membranpumpe/kompressor. Pumpemodel FT har pumpehus og membraner i PTFE og er derfor meget kemisk resistent. 100 mbar benyttes bl.a. til filtreringsopgaver og 8 mbar benyttes til evaporatorer, rotationsfordampere, geltørring, vakuumskabe m.m.

PTFE diaphragm pumps for evacuating and pumping corrosive gases and vapours. Maintenance and oil free. Pumpheads and valves are made of chemically resistant materials. Freely moving, stress resistance-optimised, structured diaphragm achieves maximum vacuum performance from even the smallest dimensions. A sealed PTFE coating on the diaphragm and a special sealing zone on the outer rim of the diaphragm make these pumps exceptionally gas-tight. High vapour and condensate compatibility is afforded by a new valve system. Compact, space-saving design. Built-in foldaway handle.

Supply requirements: 230V, 50Hz.
