Vacuum pumps Oil lubricated vacuum pumps offer the following advantages: • Air-cooled, therefore do not require coolant • Highly reliable • Low operating costs • Good resistance to condensation • Integrated oil mist separator, oil filter, check valve on suction side with sieve Vacuum pump220-240 V working voltage, dry lubricated Nr. Volt All vacuum pumps can be used with 60 Hz

Vacuum pumps 11 Vacuum pump 230/400 V working voltage, oil lubricated ) All vacuum pumps can be used with 60 Hz

Witte vacuum units feature the following: • Oil lubricated vacuum pumps with an end vacuum rate of 20mbar absolute at full suction capability of i.e. 10m3 upto 250m3 per hour • Integrated pressure difference switch, which automatically switches the vacuum pump on or off thereby ensuring vacuum during machining but avoiding unnecessary idle running • Protection switch which protects electric motor from overheating • Air filter which protects pump from dirt (made of acrylic glass with exchangeable air filter cartridge) • Careful assembly of compatible components guarantee trouble-free and...
