Vaccum Pump System
From Manufacturer: Simplicity of design, operational reliability and high quality are all key features of the rotary vane principle. The consistently high vacuum level in continuous operation is made possible with circulating oil lubrication, well-coordinated materials, and state-ofthe- art precise manufacturing. The standard oil separator ensures clean and oil-free exhaust due to its sophisticated extractor system with a large filter surface and integrated oil return.
When fitted with a gas ballast valve (optional), even large amounts of vapor can be processed. A non-return valve in the inlet flange prevents air from flowing back into the vacuum chamber when the vacuum pump is switched off. The pump is driven by a directly flange-mounted standard electric motor.
