Function and model selection
YFB breathers cover the reservoir filler opening and filter incoming air. Select mounting arrangement and air-flow size independently from the hydraulic system's oil-flow requirement.
The 150 and 700 figures identify air flow in L/min, not hydraulic oil flow. Use the applicable TT, TM or SM drawing to confirm mounting dimensions.
Use the catalogue alongside the details below, then send the complete model and application requirements for selection support.
