Can a screw air compressor be used as a vacuum pump?
Thread Content
Is there a skilled worker here? Can a screw air compressor be used as a vacuum pump, and will its lubrication system still function properly?
To represent a vacuum, a numerical value is also required. The inlet of a air compressor is usually at a pressure lower than atmospheric pressure, and any pressure lower than atmospheric pressure can be referred to as vacuum or negative pressure. Everything must comply with the scope of application indicated on the equipment label; anything within that scope can be used. It’s not allowed to go beyond the limits. For reference.
The rotor structure is different; the compressor has a high exhaust pressure, while the vacuum pump has a very low exhaust pressure.
It’s possible, but the vacuum level isn’t high enough
