GB Oil tank ST 250 Stainless steel Aluminium Sunfab offers its own range of hydraulic oil tanks ST 250 with a number of functional improvements necessary for high performance hydraulic systems. Sunfab ST 250 features an external breathing filter, which is fitted in a protected position to reduce the risk of clogging. The filter is connected to the tank via a hose. Sunfab ST 250 radically reduces the air mixture in the hydraulic oil with an oil pipe around the return filter and a tried and tested baffle plate design. Air mixture is the main reason behind noise and cavitation of the pump. Sunfab ST 250 is supplied with filter and brackets. The tank has recommended dimensions for inlet and outlet ports and is available in two different materials: ST 250 A in aluminium ST 250 S in stainless steel.
