KERSAI Three-Stage Compressed Air Precision Filter

The KERSAI series of precision filters employs a multi-stage, progressive purification solution, consisting of a Q primary filter, a P intermediate filter, and an S precision filter. These filters sequentially trap solid particles, liquid condensate, and oil mist aerosols in the compressed air, continuously improving the purity of the air supply. They are widely used in hospital medical compressed air supply systems.

Three-Stage Filtration Roles

• Q Filter (Primary Filtration): Intercepts rust, dust, and large solid particles at 3 μm, providing initial purification of the airflow and protecting downstream filter elements.

• P Filter (Intermediate Filtration): Separates liquid water droplets and condensed water from compressed air at 1 μm, removing most liquid contaminants.

• S Filter (Ultra-Precision Filtration): Captures suspended oil mist and microscopic water vapor at 0.01 μm, achieving deep purification of the air supply.

Core Product Advantages

• Multi-stage purification extends filter element lifespan by intercepting contaminants at each stage, preventing rapid clogging of high-precision filter elements and reducing long-term operational and maintenance costs.

• High-strength aluminum alloy housing: The housing offers excellent corrosion resistance and stable pressure tolerance, suitable for the standard operating pressure of air compressor systems.

• Standard manual drain ball valve: Facilitates periodic drainage of accumulated water from the filter; supports upgrading to an automatic drain valve for unattended operation.

• Modular series configuration: Can be purchased as a complete set for series use or individually selected as single-stage filters, flexibly meeting various compressed air purification needs.

• The system offers strong adaptability and can be paired with refrigerated dryers and heatless adsorption dryers to build a complete compressed air purification system.
