Hydax hydraulics offers filler breather assemble [model fb-700-tt-40] a combination unit for filtering air displacement from reservoir and for straining oil while filling. Mounting options include tank top and side mounting. Displacement capacity is 250 & 700 lpm and filtration is to 40 microns. Air displacement from underneath cap assembly improved performance. Nickel chrome or powder coated finish ensures corrosion resistance. These units come completely assembled with internal safety chain and fasteners. The mounting surface prepared as outlined in the sketch along unbroken line should be free of burrs, flat and clean to provide good sealing surface for flange. For use with hydraulic/lubrication oil reservoirs applications include machine tools, mobile equipment, industrial machinery, etc. The filler breather assembly is a must for hydraulic systems ensuring clean air passing into the reservoir, thus prolonging the life of the system components. When used as a crankcase ventilator, it helps to prolong the life of the engine oil and the oil filter. They are designed for use in machine tool construction, mining, marine and agricultural application.
