Precision Filter Element for Refrigeration Compressor Oil

　　Superior Performance and Core Specifications

　　Our air compressor oil precision filter is specifically designed for aftercooler oil lines, achieving a filtration accuracy of up to 5μm (compliant with ISO 16889 standards). It captures 99.98% of particles ≥5μm and 100% of particles ≥10μm, effectively removing metal debris, carbon deposits, and colloids from the cooling oil. This eliminates pipe blockage and compressor wear—common problems that can lead to downtime and lost profits. The filter is made of imported high-toughness glass fiber, offering excellent oil and high-temperature resistance without shedding fibers, preventing secondary contamination of the oil and equipment. All performance indicators are based on our independent testing and do not infringe on any third-party intellectual property rights.

　　This universal filter uses a standard size of 450mm (length) × 69mm (outer diameter) and can directly replace filters from over 90% of mainstream air compressor brands on the market. It is suitable for most common models on the market without any pipeline modifications. Installation and replacement are quick and easy, saving you time and labor costs. Its 1.8㎡ filter area (40% larger than standard filters) ensures smooth oil flow in the aftercooler lines, reducing blockages and maintaining stable compressor oil pressure even under high loads. Note: This product is a third-party compatible accessory and is not officially affiliated with any air compressor brand.

　　We have optimized every detail to improve efficiency and durability. An initial pressure drop of ≤0.18MPa reduces the load on the compressor oil pump, lowers energy consumption, and prevents excessive pressure loss in the aftercooler lines. Its 120g dust holding capacity is 35% higher than similar products, allowing it to hold more impurities from the cooling oil, thus extending its service life and reducing replacement frequency and maintenance costs. It operates reliably in a temperature range of -30℃ to +110℃ and can adapt to changes in cooling line temperature. The fluororubber seals offer excellent oil resistance and sealing performance, undergoing 100% leak testing before leaving the factory (≥99.9% sealing rate), effectively preventing oil leakage and waste.

　　Why choose our precision oil filter?

　　Reduce air compressor failure rate by 72%: Tested in real industrial environments, our filters maintain a filtration efficiency of over 98.5% after 800 hours of continuous use. Its multi-layer progressive filtration (coarse + fine + ultrafine) progressively captures impurities, eliminating compressor wear, oil contamination, and pipe blockage—say goodbye to costly downtime. All test data comes from our internal testing and does not infringe on any third-party test results or technical data.

　　Save 35% on maintenance and downtime: This filter cartridge has a 120-gram dust holding capacity and an average lifespan of up to 6 months (16 hours of operation per day), 35% longer than standard cartridges. Even in harsh industrial environments, it can last up to 3 months, reducing replacement frequency. Each cartridge reduces oil purification cycles by 3 per year, saving over $40 in maintenance costs per compressor. Say goodbye to expensive downtime caused by frequent filter replacements, improve productivity, and enhance your profitability.

　　Save 8% on energy and reduce operating costs: The low initial pressure drop (≤0.18MPa) reduces oil pump load, resulting in an 8% reduction in energy consumption. For a 15kW compressor, this translates to an annual saving of 1050kWh, equivalent to approximately $84 in electricity costs (at $0.08/kWh). These savings are substantial in the long term.

　　Easy installation – tool-free: The built-in handle allows one person to easily change the filter in under 5 minutes, without any special tools. The universal interface is compatible with most compressor models, eliminating the need for piping modifications and reducing maintenance and downtime. The hot-melt welding process leaves no adhesive residue, ensuring a clean system.

　　Durable for various industrial environments: Compatible with all common air compressor oils (anti-wear oil, flame-retardant oil, phosphate oil), it operates reliably in extreme temperatures (-30°C to +110°C) and is resistant to dust, moisture, and harsh environments. Whether in a small workshop or a large industrial facility, it performs perfectly—durable and consistently reliable.

　　Broadly compatible with all air compressor applications

　　Our air compressor oil precision filter is designed specifically for cooled oil lines, making it ideal for any industry or application that relies on air compressors. It is perfect for manufacturing plants, workshops, construction sites, chemical plants, pharmaceutical laboratories, food processing plants, and any other location requiring compressor-driven operation. Whether you use small portable devices or large industrial compressors, our filters meet your system's needs for optimal performance and protection. This product is independently designed and manufactured without using any unauthorized third-party copyrighted content, trademarks, or patented technology.

　　Quality assurance and reliable after-sales support

　　We always insist ontrict quality standards, with filtration performance and product quality meeting ISO 16889 and ISO 12500 requirements. Every filter undergoes 100% pre-delivery testing (sealing, pressure drop, filtration efficiency) for a ≥99.8% qualification rate. We offer a 12-month warranty—7-day no-questions-asked return/exchange for non-human damage. Our team provides free technical support: product selection, installation guidance, and troubleshooting. Rest assured, our product design, materials, and performance metrics are independently developed, with no infringement on third-party patents, trademarks, or intellectual property.
