Oljefri membranpump/kompressor. Modell FT har hölje och membran i PTFE och är därför mycket kemiskt resistenta. 100 mbar används till filtrering och 8 mbar används till förångare, rotationsindunstare, geltorkning, vakuumskåp mm

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.
