Import Air Breather Filter Pqa Pqb Series — Buy in Bulk from Supplier in China

The Air Breather Filter PQA/PQB Series is engineered to protect hydraulic reservoirs from airborne particulate and moisture ingress during system breathing. It features a high-efficiency filtration medium that captures contaminants down to sub-micron levels, with a robust housing designed for industrial environments. The series supports flow rates compatible with hydraulic systems of varying capacities, ensuring consistent performance under fluctuating pressure conditions.

Constructed from corrosion-resistant materials, the filter integrates a moisture-absorbing desiccant to prevent condensation inside the reservoir. Typical industry builds for such filters use synthetic media with efficiency ratings of 98% or higher at 3 microns, and housings rated for pressures up to 10 bar. The design includes a replaceable element, and standard configurations often feature a 1/2" NPT or BSP thread for mounting, with optional adapters for custom installations.

These filters are deployed in sectors like manufacturing, construction, and mobile hydraulics where equipment uptime is critical. Buyers typically specify models based on reservoir volume and environmental exposure, with common trade terms including FOB Shanghai or CIF to major ports. Confirm compatibility with your system’s breather valve and reservoir size, as well as the filter’s pressure drop at your operating flow rate before ordering.
