Key Features & Advantages

• How the Oil Separation Actually Works: We use a three-step separation setup here, not just a single filter layer. First, the inlet baffle slows the oil-air mix right down, so the bigger oil droplets settle out on their own. Then, the middle high-density glass fiber media catches the tiny oil mist — down to 0.1μm — that’s where that 99.99% separation efficiency comes from. Finally, the inner coalescing layer groups small oil droplets into bigger ones, which drain back to the compressor’s oil sump automatically. This multi-step setup means way less oil getting carried over, cleaner compressed air, and you won’t have to change the element nearly as often as single-stage separators.
• ISO 9001 Certified (No Shortcuts on Quality): Every  oil separator we make at our Jiangxi factory goes through hard tests before we ship it out: checks to make sure it separates oil right, holds pressure properly, resists corrosion, and doesn’t leak. We meet every ISO 9001:2015 standard, so you won’t get a dud that causes oil leaks or dirty air. This certification means our part lines up with industrial rules in Europe, North America, and most global markets — no hassle with site compliance or procurement risks.
• Built Tough for Hard, Daily Use: The separator has a 1.5mm thick carbon steel housing — we powder-coat it for extra rust protection, and it’s thicker than the 1.0mm steel most other suppliers use for this model. It holds up to 1.6MPa of pressure and handles temp swings from -20℃ to 120℃ without warping, no cracking. The filter element uses imported synthetic glass fiber media that holds up against oil breakdown, so it lasts 3000 to 4000 operating hours (depends on your compressor’s oil type and how you use it). That’s about 25% longer than most other 2901077901 separators out there — saves you time on maintenance and money on replacement parts.
• Fits Like the OEM Part, No Fuss Installation: We built this 2901077901 separator to match the original OEM part’s exact size, flange, and mounting spots. We cut the sealing gaskets in-house from oil-resistant rubber, so they fit tight — no air or oil leaks. You don’t have to drill new holes, adjust brackets, or mess with your compressor’s oil system at all. Just take out the old separator and bolt this one on. Most guys get it installed in under 30 minutes, so your compressor isn’t down any longer than it needs to be.
• Factory Prices, Steady Stock (We Make It Ourselves): We’re the direct manufacturer — no middlemen adding extra cost, so you get wholesale prices without skimping on quality. Our factory makes over 5,000 of these 2901077901 separators a month, so we can handle bulk orders (200+ units easy) and keep stock on hand for your regular maintenance. If you’ve got questions about whether it fits your compressor brand (like Atlas Copco, Ingersoll Rand, or Sullair), need help with installation, or want a small custom tweak, our tech team’s here — no passing you around, just straight answers.

• Manufacturing & Automotive: Go-to for air compressors in auto body shops (painting lines can’t have oil — it ruins the finish), electronic part factories (oil wrecks circuit boards fast), and precision machine shops. It keeps compressed air clean, so your end products hit quality marks and downstream gear doesn’t wear out sooner than it should.
• Construction & Mining: Great for mobile air compressors on job sites, mines, or road work. The tough powder-coated housing stands up to dust, dampness, and rough use on site — even in dusty mine shafts or rainy construction zones — so the separator keeps working reliably, no leaks to mess up your project.
• Power Generation: Fits air compressors at thermal plants, hydropower stations, and solar/wind setups. These sites run compressors 24/7 at full blast, and our separator keeps oil separation on point — so those control systems and pneumatic tools get clean air, and power generation stays steady without hiccups.
• Food & Beverage Processing: Works for air compressors in food packaging plants, bottling facilities, and dairy operations. Food-grade jobs need oil-free air to meet hygiene rules (FDA, EU 10/2011) — our separator’s 99.99% efficiency keeps oil out of the air stream, so you don’t have to worry about oil contaminating your products.
• Logistics & Warehousing: Good for air compressors powering pneumatic conveyors, packaging machines, and warehouse forklifts. Clean compressed air keeps these systems running smooth — no oil gumming up valves or cylinders — so you don’t get surprise breakdowns that slow down order packing or shipping.
