Air Compressor Oil Filter Element 47710806001 – Reliable Lubrication Protection for Screw Compressor Main Units
Product Definition
The oil filter element 47710806001 is installed within the oil circulation loop of screw air compressors, tasked with continuously removing suspended contaminants from the lubricating oil. Over time, the oil accumulates degradation by‑products from thermal cracking, fine metallic debris from friction pairs, and airborne dust particles that have entered the system. If not effectively filtered, these impurities accelerate bearing wear, damage rotor coatings, and shorten the interval between compressor overhauls. This filter element is specifically engineered to address these contamination challenges.
Construction and Functional Logic
The element adopts a cylindrical pleated configuration, with filter media made of surface‑modified glass fiber composite felt. Under system pressure, oil flows from the outer surface inward through the media and into the central collection tube, where contaminants are trapped within the media depth – this depth‑loading mode ensures that multiple layers participate in particle capture, delaying surface blinding.
A bypass valve is integrated into the filter base. When the retained contaminant load raises the pressure differential to the preset range, the bypass valve mechanically opens, allowing oil to travel around the filter media and directly reach the compressor lubrication points. The core value of this design is that even when the element has reached its replacement threshold, the compressor continues to receive adequate oil flow, preventing bearing seizure or rotor locking caused by oil supply interruption.
Product Features
Graded density along media thickness – Fiber packing density increases progressively from outer to inner layers, with coarse particles captured on the outer zones and fine impurities retained deeper within, achieving balanced contaminant distribution across the entire media depth.
Oleophobic surface treatment – Media surfaces are chemically modified to reduce oil adhesion resistance, keeping the impact on oil pump load consistently minimal.
Mechanically robust bypass valve – The valve assembly employs fatigue‑resistant metal springs and precision‑ground poppets, delivering stable activation thresholds with crisp open/close responses – no calibration or adjustment required.
Integrated end cap and center tube forming – End caps and center tubes are assembled through a single‑step press‑fit process, minimizing weld‑induced distortion and ensuring accurate axial and radial positioning within the filter housing.
Comprehensive sealing system – Nitrile rubber seals, selected for oil and temperature resistance, are designed with optimized compression ratios to create reliable static seals upon installation, eliminating internal bypass leakage.
Straightforward disassembly for disposal – Metal end caps can be readily separated from the filter media, simplifying material sorting and reducing waste handling costs.
Manufacturing Standards and Process Control
XINXIANG MENGMA FILTER CO.,LTD. leverages the mature filtration industry infrastructure in Xinxiang to operate a complete production flow – from media slitting, pleating and forming, end cap bonding, to final air‑tightness testing. Media permeability and crush resistance are verified through sample testing for each production batch. External dimensions of finished elements are 100% inspected using go/no‑go gauges to ensure consistent mounting interface accuracy on every unit shipped. We place strong emphasis on recording and traceability of process data, supporting our customers' expectations for parts uniformity and reliability.
