Robust technology
The GVS 20-300 series operates according to the proven
oil-sealed rotary vane principle that has been successfully used
for many years in all general vacuum applications of industry.
The GVS 20-300 series is a robust and highly regarded product
coming from a technologically advanced market leading design.
Innovative features
Atlas Copco has packed the GVS 20-300 range with innovative
features that ensure the highest possible performance at the
lowest possible lifecycle cost. The built-in gas ballast is fitted as
standard to assist in water handling capability. Other integrated
functions include the lubricant retention and return mechanism
which means that these machines are suitable for continuous
operation between 400 mbar(a) and their ultimate pressure.
Clean and efficient
The oil separation circuit of the GVS 20-300 has been optimized
to minimize oil vapors in the exhaust gas. The inlet non-return
valve protects the vacuum pump against counter rotation in the
event of stopping without venting. This device also protects the
point of use against back sucking of oil.
