Product Introduction
The Gardner Denver 89559379 oil filter element is designed specifically for Gardner Denver rotary screw air compressors (such as the ES 11/15/18/22/30/37 and VS 20/25/40 series). It removes impurities from the compressor's oil circuit during operation, ensuring clean and stable operation of the equipment's lubrication system. This filter element utilizes paper filter media and a steel/plastic composite structure. It has an outer diameter of 93mm, an overall height of 172mm, a standard thread size of G3/4"-14, a net weight of 0.5kg, and a lifespan of approximately 3000 hours. Both OEM parts and compatible replacements from multiple brands (such as MAKO AIRTEK and Industrial Air Power) are available to meet different budgets and maintenance needs.

Product features
1.High-efficiency impurity interception: 5-layer gradient density filter paper design, dirt holding capacity increased by 40%, extending the oil replacement cycle.
Pressure-resistant and leak-proof structure: The end cover adopts laser-welded steel mesh + engineering plastics to withstand pressure fluctuations and avoid the risk of filter shell rupture.
2.Low flow resistance optimization: Diamond pleat layout increases the filtration area, maintains a stable oil flow, and reduces compressor energy consumption.
In line with ISO 14001 environmental standards, the filter material can be incinerated to reduce industrial waste pollution.
3.Why choose the original filter element?
Third-party alternatives (such as MAKO AIRTEK) are 15-20% cheaper, but the measured impurity interception rate is only 82% (original ≥95%), and long-term use may accelerate bearing wear.

Product application areas
This gardner denver filter element serves the following high-load industrial scenarios:
1.Manufacturing: Automotive spraying lines, cnc machine tool pneumatic systems, to ensure oil-free air output.
2.Energy field: Natural gas pipeline booster stations, power plant instrument air source guarantee.
3.Medical and food: Medical ventilators, food packaging inflation equipment, ISO 8573-1 class 0 certified.
4.Engineering machinery: Mining drills, shield machine hydraulic oil circulation filtration.

Product details
1.Anti-counterfeiting traceability: The original packaging is printed with Gardner Denver laser anti-counterfeiting code and batch label, and supports official website verification.
2.Installation compatibility: The threaded interface is compatible with G3/4"-14 and 1/8 NPT, and is suitable for mainstream models around the world.
3.Failure warning mechanism: When the filter paper is saturated, it will automatically trigger a pressure difference alarm (≥0.5 bar), reminding you to replace it in time.

Product Proof
1.Authoritative distribution endorsement: John Bouchard & Sons, as an authorized distributor of Gardner Denver, confirms that 89559379 is directly supplied by the original supply chain.
2.Terminal verification: US industrial users report that the overhaul cycle of Gardner Denver compressors using this filter element is extended to 8,000 hours (the industry average is 5,000 hours).
3.International alternative certification: The filter element with the same parameters (P550268) made in China has passed CE/PED certification, and its performance is comparable to that of the original factory.
Intimate service
1.Global logistics: Support dhl/fedex direct delivery, south China warehouse delivers to asia pacific in 3 days, and europe and the united states in 7 days.
2.Technical response: Provide compressor model identification service, send the host nameplate photo to confirm the filter element compatibility.
3.After-sales guarantee: Provide 12-month warranty, unconditional replacement for non-human damage.
FAQ
Q1: The third-party filter element is nominally compatible with 89559379. Can it replace the original one?
A:It can be used in an emergency, but it may damage the main engine in the long run. For example, after a paper mill used non-original filter elements, the annual failure rate of the compressor increased by 27%.
Q2: Is the 3000-hour filter element life applicable to high temperature environments?
A:3000 hours is based on a 25°C environmental test. If the oil temperature is >80°C for a long time, it is recommended to shorten it to 2000 hours for replacement.
Q3: How to verify the authenticity of the original factory purchased?
A:Three-step confirmation: ① Scan the packaging anti-counterfeiting code; ② Check whether the filter paper folds are uniform and have no burrs; ③ Request a Gardner Denver shipping order.
Q4: Do you provide customized parameter filter elements?
A:Support OEM, and batch customization can be provided after providing pressure and interface drawings.
