Coalescing filtration works by forcing contaminated airflow through a fiber media element that causes tiny droplets to merge and drain away, protecting downstream tools, pneumatic controls, and instrumentation from fluid carry-over. This unit features a 1\/2 inch port size and includes an integrated sight glass for quick visual inspection of bowl conditions without disassembly. It is typically installed by industrial maintenance technicians, HVAC mechanical contractors, or compressed air system specialists.\u003c\/p\u003e\u003cp\u003eThis filter is suited for use in compressed air distribution systems found in light industrial, commercial HVAC mechanical rooms, manufacturing facilities, and process control environments. The 1\/2 inch port makes it a practical fit for mid-flow branch lines where oil and moisture contamination must be controlled ahead of sensitive equipment such as pneumatic actuators, regulators, solenoid valves, and instrumentation. The sight glass allows service personnel to monitor bowl fill levels during routine walkthroughs without interrupting system operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCoalescing filter element removes oil aerosols and fine water mist from compressed air\u003c\/li\u003e\n\u003cli\u003e1\/2 inch port size suits mid-flow compressed air branch lines\u003c\/li\u003e\n\u003cli\u003eIntegrated sight glass allows visual bowl inspection without disassembly\u003c\/li\u003e\n\u003cli\u003eCompact footprint at 2.87 inches wide and 9.25 inches tall for tight installation spaces\u003c\/li\u003e\n\u003cli\u003eSold individually for single-point replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement coalescing filter element assembly for 1\/2 inch port compressed air filter stations.

Before servicing or replacing the filter, depressurize and isolate the affected line segment at the nearest isolation valve and verify zero pressure with a gauge before loosening any fittings. Follow applicable mechanical codes and the system manufacturer guidelines for thread sealant use on NPT connections. Do not exceed the rated pressure of the filter assembly or use the sight glass bowl as a structural handle during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Coalescing Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Sight Glass\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILKERSON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M28-04-CH00B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKERSON","offers":[{"title":"Default Title","offer_id":51538751717682,"sku":"M28-04-CH00B","price":394.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea190d88005c54ea2ea15b5350ca91fe.jpg?v=1785826100","url":"https:\/\/voomisupply.com\/products\/wilkerson-m28-04-ch00b-coalescing-filter-1-2-inch-port","provider":"Voomi Supply","version":"1.0","type":"link"}
