The 800-322 Lower Cage is a structural and protective component used in a wide range of Airless Sprayer, Advantage, Impact, Performer, and PowrTex models. It encloses the lower section of the pump or motor, shielding internal parts from physical damage, debris, and environmental contaminants while also providing mounting points for associated components.
Constructed from heavy‑gauge steel, this cage is designed to withstand the rigors of job site use. It helps maintain proper alignment of the pump and motor, and its open design allows for cooling airflow. Over time, the cage can become bent from impacts, cracked from stress, or corroded from chemical exposure, compromising its protective function. Replacing a damaged lower cage restores equipment safety, prevents further damage to internal parts, and ensures reliable operation.
