HFV series Vacuum pump oil

Performance

※ HFV-100# conforms to the Standard SH 0528,while HFV-100a is an ideal substitute of HFV-100 vacuum pump oil.

※ Good viscosity-temperature characteristic to ensure better vacuum degree than HFV-100 vacuum pump oil at same condition.

※ Superior anti-oxidation property of HFV-100a,it is available for the situations if needed.

※ Better demulsibility compared with HFV-100 to separate oil from water rapidly.

 

Application

※ Applicable to all kinds of sliding-vane,piston vacuum pumps at rough vacuum conditions.
