Trivac D 2.5 E

The TRIVAC E pump is an oil sealed vacuum pump operating according to the rotary vane principle . Oil which is injected into the pump chamber is used for sealing, lubrication and cool- ing purposes



Highly reliable

Small and compact

Quiet operation

Environmentally compatible (low oil consumption, EMI compatible, IP 54 protection)

Process quality (low backstreaming of oil)

Motor for all standard supply voltages and frequencies

Safe and intelligent vacuum protection (hermetically sealed)

Free of yellow metals

Compliance with international stand- ards (CE)

Suitable for continuous operation at 1000 mbar (750 Torr)

Low power consumption

Better individual performance given by 3 stage gas ballast device

High water vapor tolerance

Simplified customizing ability
