FILTERS FOR COMPRESSORS
Spin-on oil filters
Thanks to its experience in the hydraulic sector, SOTRAS has developed a range of oil filters, especially suitable for screw and vane compressors and vacuum pumps applications, bearing in mind that these filters will have to endure sudden changes and extreme limits in pressure and temperature.
The oil filters that SOTRAS offers are usually of the spin-on type and can be provided with a by-pass valve, if it is not already to be found on the heads or in the lubrication circuit.
Generally the most commonly used filtering media is made of cellulose, however fiber glass and metallic mesh versions are available on request.
Every batch undergoes stringent laboratory performance tests in terms of resistance to cyclic and maximum working pressure.
