Titan OEM Air Motor Piston
The Titan 0533394 is an OEM piston designed for the AirCoat 620 and PowrCoat 630 sprayers. This piston is the primary moving component of the air motor assembly, where it is driven by compressed air to create the reciprocating motion that powers the fluid pump. Replacing a damaged or worn piston is essential for maintaining proper air motor performance, preventing power loss, and ensuring reliable sprayer operation. Note: The AirCoat 423 uses a different piston (part 0533382).
