Product Introduction

Compressed Air Precision Filter is a first-stage filtration device for compressed air containing dust, oil, rust and moisture. It is an auxiliary compressed air equipment that helps remove unnecessary and harmful pollutants, including aerosols (liquid droplets of oil/water), particulates (fine solid particles like dust and metal debris) and vapor (gasified liquid). It is widely used in pneumatic equipment, medical instruments, food and pharmaceutical industries, filtering air particles, oil, rust, moisture and aerosols.

Product Features

  1. leak-proof filter element: Special anti-leakage technology ensures reliable filtration performance.

  2. corrosion-resistant housing: Inner cavity treated with anodic oxidation, outer shell coated with epoxy resin powder.

  3. imported filter material: Filter element made of imported borosilicate glass fiber.

  4. fine fiber structure: Small diameter and smooth surface of fibers in the device.

  5. effective oil mist removal: Efficiently filters solid impurities and oil mist, quickly eliminating oil fog.

Working Principle

  1. Contaminated compressed air enters the first-stage filtration device.

  2. When passing through the first-stage cylindrical mesh filter, particles are captured by coalescence, and moisture condenses into large water droplets.

  3. In the separation chamber, the airflow slows down, causing further particle agglomeration and water mist condensation on the honeycomb water collector.

  4. Water carrying impurities flows to the drainage device and is discharged via automatic or electric drain valve.

  5. Over 95% of water droplets, oil liquid and large particles are removed by the first-stage filter, and the air enters the second-stage filter element.

  6. Passing through the second-stage special fiber filter web, the compressed air generates numerous small vortices, accelerating dozens of times to form a vacuum at the center, gasifying and removing remaining water droplets, and completely capturing particles as small as 5 microns.

  7. After two-stage filtration, clean, dry, dust-free, rust-free and oil-free compressed air is obtained, ensuring normal operation of pneumatic equipment and extending service life.
