HC9021FDP8H Replacement PALL Hydraulic Glass Fiber Filter Element

HC9021FDP8H is a highprecision domestic replacement filter element for PALL hydraulic filters, constructed with multilayer composite glass fiber media and depthtype filtration structure. It is applied for highprecision oil purification in hydraulic systems, effectively trapping fine solid particles, oil sludge and oxidation contaminants to improve oil cleanliness level. It reliably protects precision components such as servo valves, proportional valves, cylinders and hydraulic pumps, and serves as a full drop-in replacement for original PALL filter elements.

Product Advantages

1. Depthtype glass fiber filtration delivers high precision and large dirtholding capacity with long clogging cycle, longer service life than ordinary filter elements.

2. High-strength support structure resists high pressure and flow impact; no deformation or delamination under highpressure pipeline conditions.

3. Precise dimensional compliance with original specifications, direct interchange without equipment modification.

4. Consistent and stable filtration performance reduces malfunctions including hydraulic valve sticking, abnormal noise and internal leakage, improving overall equipment reliability.
