If you’ve ever spent hours fighting to align a mismatched flange on an air oil separator, only to end up with a slow oil leak that drips onto your factory floor for weeks, you know how frustrating poorly designed replacement parts can be. Generic flange-type separators always have dimensional inconsistencies that turn a simple maintenance job into a full-day headache.Their thin stamped metal flanges warp easily under high pressure, leading to persistent leaks and thousands of dollars in wasted oil. Our company product OS-1010 air oil separator is engineered specifically to eliminate this common pain point, serving as a perfect direct replacement for OS2101, 10012674, 3241501200, 4930152121 and 4930152401.It is built entirely from heavy-duty stainless steel with an integrated built-in flange design, every unit arrives brand new and precision-machined to exact OEM specifications. There are no extra adapters and no custom gaskets, no tedious trial-and-error alignment—just bolt it directly to your compressor housing. It delivers industry-leading oil removal performance, trapping 99.99% of fine oil mist from compressed air and protecting your downstream pneumatic tools, production lines and finished products from costly contamination.
What sets this separator apart from every other option on the market is its one-piece built-in flange construction, which eliminates the weak point where separate flanges are welded or bolted to the separator body. This seamless design creates a permanent, leak-proof seal that will never fail under normal operating conditions, even when your compressor runs 24/7 at full load. The all-stainless steel build resists rust and corrosion far better than carbon steel alternatives, making it ideal for high-humidity environments and facilities that use water-based cooling systems. We use premium imported micro-glass fiber media that maintains consistent separation efficiency throughout its entire service life, with minimal pressure drop to keep your compressor running efficiently and keep your energy bills low. This separator is trusted by facilities across all industries that demand clean, oil-free compressed air, including automotive manufacturing, food and beverage processing, pharmaceutical production, electronics assembly and general industrial operations.
Before installing your new separator, take a few minutes to thoroughly clean the mating flange surface on your compressor to remove any old gasket material, oil residue or debris that could prevent a proper seal. Never use liquid sealant on the gasket, as it can break down and clog the oil return line, which is the leading cause of premature separator failure. Tighten the flange bolts evenly in a crisscross pattern to ensure uniform pressure across the entire gasket surface, and replace the separator every 3000 to 4000 operating hours, or sooner if you notice increased oil consumption or oil in your air lines. We ship all orders in heavy-duty corrugated boxes measuring 39×39×39cm, with each unit individually wrapped and protected to prevent damage during transit.
