DRV40 (40m3/h) Double Stage Oil Sealed Rotary Vane Vacuum Pump
When the ambient temperature range is under 40 ℃, the air inlet pressure is less than 1300 Pa. It's allowed for long-term continuous operation. However, when the pumped gas relative humidity is above 90%, the gas ballast valve should be opened.
