Product Description

Product Description

Oilless Variable Speed Rotary Screw Air Compressor RDO-315A/W

What is dry oil-free?
Level 0 oil-free, that is, the total oil content (oil brought in during compression + oil vapor in the air) index reaches ≤0.01mg/m³
"Oil-free" means that the gas is not in contact with oil at all during the compression process, that is, there is no oil lubrication between the compression chamber or the rotor of the compressor, but the bearings, gears and other parts in the compressor are still lubricated with ordinary lubricants. Lubricated in the same way, but between these lubricating parts and the compression chamber, an effective isolation shaft seal is adopted.
