This Hydraulic Tank Air Breather Filter & Filler Cap (PN 803165591 / Model QUQ2-10×0.63) is a dual-function reservoir accessory for XCMG hydraulic systems—serving simultaneously as the tank's pressure-equalization vent and as the filtered fill port for new oil. Decoded from the QUQ2 model: 10 = 10 μm air filtration accuracy; 0.63 = 0.63 m³/min air flow @ ΔP=0.02 MPa (suitable for mid-size reservoir breathing cycles). The unit also integrates a 0.5 mm oil-fill mesh behind the air filter element, so fresh hydraulic oil poured through the cap gets screened before entering the tank—preventing contaminant ingress at both the "breathing" and "refill" entry points. Housing is cast aluminum alloy with a removable/replaceable element (wire mesh or sintered type) and nitrile sealing ring, operating from -20°C to +100°C under atmospheric differential. Threaded mount matches OEM tank boss—no adapter needed. Each unit is visually inspected for thread integrity and element seating before shipment.
