1.0 The QS5’s High Performance Features

 High vacuum, high speed pump

Two-stage rotary-vane design provides deep, 15 micron ultimate
vacuum and reduces evacuation time.

 Internal oil pumping design

Internal oil pump lubricates the pump chamber and bearings.

 Anti-backflow design

Anti-backflow on the inlet prevents oil from re-entering the system in
the event of a power failure, maintaining system purity.

 Gas ballast

Gas ballast exhausts moisture and condensation from inside the
pump, helping to keep the oil cleaner and preserving pump life.

 Innovative oil exhaust/demister

The exhaust demister dissipates oil vapor and keeps oil from getting
on the pump housing.

 Rugged and comfortable handle

Handle design makes it easy to carry the pump while the “no slip”
rubber grip stays cool.

 High quality design and material

Aluminum oil housing, base and motor cover makes the pump light
while ensuring durability.

 Thermal protection

The thermally-protected motor ensures safe operation.
