The Airless Sprayer / Performer / PowrTex 800-901 filter base housing is the main structural component of the fluid filter assembly. It contains the filter screen cavity, inlet and outlet fluid passages, and mounting points for the filter bowl, pressure control knob, and other components. All filtered fluid passes through this housing.
The filter base housing is subjected to high pressure, thermal cycling, and mechanical stress. Over time, it can develop cracks, threads can strip, or sealing surfaces can become damaged. A compromised housing can cause leaks, pressure loss, and contamination of the spray fluid. Replacing the filter base housing restores proper filtration and ensures reliable fluid delivery.
