Oil-free screw compressors
Much like the oil-lubricated variant, oil-free screw compressors also have other names. Users will most often refer to them as oilless compressors or no oil compressors. The names, however, can be somewhat misleading. The naming convention for these compressors comes from the presence (or absence, in our case) of oil in the compression process.
An oil-free compressor will still use lubricant for its other processes, such as motor cooling or removing heat from the rotors. Some variants will use water as an alternative lubricant. Our AQ water-injected compressors are such an example. Other variants rely on a special coating applied to the rotor elements, which eliminates the need for lubricants.
