FOCUSFILTRATION is a professional air compressor filters manufacturer and OEM supplier based in China, focused on high-performance filtration solutions for screw air compressors, centrifugal air compressors, vacuum pumps, and train and subway compressor applications. From single filter elements to complete air compressor filtration systems, we design and manufacture filters that keep compressed air clean, protect rotating equipment and control oil carryover as low as 2 ppm under specified operating conditions.
An air compressor filtration system is the key part of any compressor package. Every stage matters: the intake air filter keeps dust out of the air end, the oil filter protects the lubrication system, the oil separator removes oil from the compressed air, and inline filters polish the air downstream. When each filtration stage performs, the compressor runs cooler, more efficiently and with a longer service life. That is exactly the performance our customers expect from a filter manufacturer, and the reason many compressor brands around the world trust FOCUSFILTRATION as their OEM supplier and aftermarket partner.
Screw Compressor Air Filter — The screw compressor air filter, also known as the air filter element or intake filter, removes dust, moisture and airborne contaminants before they enter the compressor. Our air filters are engineered for high dust-holding capacity and low pressure drop, supporting stable airflow and reliable compressor performance. We supply both original equipment and air compressor air filter replacements for all major compressor brands.
Screw Compressor Oil Filter — The screw compressor oil filter removes impurities from the lubricating oil and protects compressor components during long-term operation. Manufactured with high-quality filtration media, our oil filter elements offer a 10 µm rating to stop particles from the oil circulation, keeping the lubrication system clean and extending the life of the air end and bearings.
Screw Compressor Oil Separator — The air-oil separator is one of the most critical components in a rotary screw air compressor. Our screw compressor oil separators and air-oil separator elements can be designed for up to 8,000 hours of service life, while spin-on separators offer a compact, easy-to-replace option for aftermarket maintenance. With oil carry-over controlled below 2 ppm, our separator elements deliver clean compressed air and lower the operating cost of the compressor system.
Inline Filter — After the air leaves the separator tank, it enters the after-compressor line. Our inline filters and line filters further stop small oil particles and fine contamination downstream, producing clean, dry compressed air for industrial air filtration systems. Inline filtration is essential wherever oil-free compressed air quality is required.
Centrifugal Air Filter — For demanding intake conditions, our centrifugal air filters provide 10 µm primary and 2 µm secondary filtration to block particles before they enter the compressor. This air compressor air filter element supports cleaner intake air, lower maintenance frequency and stable compressor performance.
Vacuum Pump Filters — Screw vacuum pumps need the same protection as screw compressors. FOCUSFILTRATION manufactures a full range of high-performance vacuum pump filters, including vacuum pump air filters, vacuum pump oil filters and vacuum pump oil separators, with oil carryover controlled below 3 ppm. We OEM for many big brand vacuum pumps and support screw vacuum pump systems worldwide.
Train and Subway Compressor Filters — FOCUSFILTRATION is the only filter manufacturer in China able to supply train and subway filtration solutions. Our train compressor filters and air-oil separators are designed for the demanding reliability and long service intervals of railway compressor systems, supporting rail operators and OEMs with dependable filter replacements.
