The 451-220 Hydraulic Filter is a genuine OEM replacement filter designed for hydraulic systems in PowrBeast, PowrLiner, PowrTex, and PowrTwin series airless sprayers and related equipment. It removes particulate contamination from hydraulic fluid, protecting sensitive components such as hydraulic pumps, motors, control valves, and cylinders from abrasive wear and premature failure.
This filter incorporates high-efficiency filter media with a specific micron rating to balance filtration performance with flow capacity. It includes an integral bypass valve that allows fluid flow to continue if the filter becomes restricted, preventing starvation of the hydraulic system. The filter housing is designed for easy replacement during routine maintenance intervals.
Regular filter changes are essential for hydraulic system health. Contaminated fluid can cause valve sticking, pump wear, reduced performance, and complete system failure. Using this genuine replacement filter ensures proper fit, correct bypass valve setting, and reliable contamination control.
| Contaminant removal | Removes particles, sludge, and debris from hydraulic fluid |
|---|---|
| Component protection | Prevents abrasive wear to pumps, motors, valves, and cylinders |
| Fluid cleanliness | Maintains hydraulic fluid within specified cleanliness levels |
| Bypass protection | Integral bypass valve allows flow if filter becomes restricted |
| Scheduled maintenance | Follow manufacturer interval (typically every 200-500 hours) |
|---|---|
| Slow / sluggish operation | Hydraulic functions respond slowly or erratically |
| Unusual noise | Pump whine or knocking indicates possible contamination |
| Visual contamination | Fluid appears dark, milky, or contains visible particles |

When replacing the hydraulic filter, it's good practice to inspect these related components, as they are often serviced during routine maintenance.
Always use fresh, clean hydraulic fluid of the correct specification when changing the filter. Contaminated fluid will quickly clog a new filter.
Some filter assemblies include a sealing gasket or O-ring that should be replaced with the filter to prevent leaks.
In some systems, a coarse suction strainer protects the pump. Inspect and clean if necessary during filter service.
