Description"BOTH" VRD series pumps are designed for reliable long
time continuous operation, they will take your equipment's vacuum
down to 0.3 micron in minutes. Comes standard with all necessary
fittings and a high capacity exhaust oil mist filter which also
returns trapped pump oil back to the pump and makes the pump
quieter to run. Multi-level gas ballast is designed to allow
purposefully pull a less deep and slower vacuum by opening the gas
ballast, allowing dry air to go directly into the pump and diluting
the vacuum pull, and it also helps keep moisture, solvent, and
other contaminants from getting stuck in the pump, and instead
passing through to the exhaust. It is important to note that pumps
should always be ran in a well ventilated area· Tow-Shift
adjustable gas ballast valve satisfies different requirements of
condensable vapor(such as water vapor) to be exhausted· Out of pump
in different processes. Dual protection of oil anti-sucking back
ensures vacuum system from oil pollution when pump· Stops running
and needs to be easily restarted. Forced oil circulation system
consisted of oil pump and constant pressure oil supply mechanism
ensures stable running of the pump.· Less components are used, easy
to maintain and repairApplication· Rotary Vane Vacuum Pump
corollary use with freezer dryer to reach vacuum state, it's an
essential corollary equipment in medicine freeze drying, biology,
food industry and agricultural products deep processing· Rotary
Vane Vacuum Pump corollary use with vacuum drying oven for
maintaining vacuum state inside the oven, they mainly applies in
powder drying and baking in vacuum conditionCompany
