High Pressure Filter is purpose-built to handle the most demanding filtration applications. Designed to withstand input pressures up to 6000 psi, this rugged filter is ideal for use in high-pressure pneumatic systems, including pipelines, offshore platforms, and sour gas operations. Available in ¼” NPT inline mounting configurations—with or without an additional outlet port in the cap—the AFH-316 provides maximum flexibility for system integration.

Huilong medium pressure filters are suitable for fluid filtration in medium pressure hydraulic systems. Aluminum alloy is used to construct the filter cap and base. Other materials can also be adopted according to application requirements, assuring the efficiency of contaminant removal. The differential pressure indicator and bypass valve are optional upon request.

Huilong suction filter is mounted on the oil inlet port of the oil pump for protection of the oil pump and downstream hydraulic unit against contamination, improving cleanliness of the hydraulic system.

The return filters are designed for fine filtration of the return oil in hydraulic systems. They can keep the return oil clean by removing the outside contaminants or progressive contamination caused by the wear of components, such as fibers, slag, rubber particles of sealing wear and metal particles of parts wear.
