VPS - Model C450 -Booster / Dry Screw vacuum Pumps
Excellent corrosive gas and entrain liquid handling capabilities and realizes 10-3 torr vacuum degree (VPS dry vacuum pump includes the standard advantage of the P Series(Single Pitch) model ad following details), (Low ultimate pressure, corrosion resistance, cooling effect, etc.) Low Ultimate Pressure The dry vacuum pumps can operate continuously in all the ranges of pressure from the atmosphere to the ultimate pressure, and it can reach 0.0075Torr(1Pa) by itself and has high efficiency. Corrosion Resistance Design - Suitable for pumping Toxic, Corrosive, and condensable gas by special coating (PTFE, PFA, Ni, NIFA). - Prevents condensation of corrosive gas through lowering vapor pressure by the gas ballast.- Casing: Ductile Iron(Teflon Coated, PTFE)
- Screw: Ductile Iron(Teflon Coated, PTFE)
