Parameter
Number of compression stages
Ultimate pressure
Maximum exhaust back pressure
Temperature of the air leaving the discharge (approximate)
The pump is developed to work constantly at inlet pressures from ultimate vacuum up to
atmospheric pressure. The maximum allowed inlet pressure is 200 mbar(g). In case of
even higher inlet pressure, please contact your pump manufacturer.
