CBS UFI
CBS UFI Filters are spin-on cartridge air breathers designed for the protection of hydraulic reservoirs. Featuring a steel body and fine 3 µm filtration capability, they offer a maximum flow rate of up to 2,800 l/min. Available with weld-on or flanged connections, they ensure quick element replacement and full compatibility with a wide range of ISO-class hydraulic fluids. Ideal for operation between -25°C and +110°C.
The CBS series offers an effective and practical solution for filtering incoming air in hydraulic reservoirs. Designed as air breathers with a replaceable spin-on cartridge element, CBS UFI Filters combine high filtration efficiency with maximum maintenance simplicity, making them ideal for industrial applications that require reliability and fast service operations.
The construction of the CBS filters is engineered to ensure robustness and long service life:
These filters are designed to handle significant airflow, with a maximum flow rate (Qmax) reaching 2,800 l/min in the larger models (Series 21 and 22). The operating temperature range is very wide, from -25°C to +110°C, allowing use in varied environmental conditions.
CBS filters also offer full compatibility with hydraulic fluids HH, HL, HM, HR, HV and HG (according to ISO 6743/4).
The CBS range offers installation flexibility with two types of tank connections:
No pressurization valve is provided (option W is standard for all models).
