Titan part 0533591 is a suction set filter used to remove debris and contaminants from coating materials as they enter the pump on the AirCoat 423 spray system. When the original filter becomes clogged or damaged, it can cause restricted flow, pressure loss, and inconsistent spray performance. This filter restores proper filtration and ensures reliable fluid delivery.
The Titan part 0533591 Suction Set Filter is a filtration component designed specifically for the AirCoat 423 spray system. This filter attaches to the end of the siphon tube and removes debris and contaminants from coating materials before they enter the pump, protecting internal components and ensuring consistent spray quality.
A clogged or damaged suction filter can lead to restricted flow, pressure fluctuations, pump cavitation, and tip clogging. Replacing with this genuine component ensures proper filtration, protects pump packings and valves, and maintains reliable performance in professional finishing applications.
Filtration Insight: The suction filter is your first line of defense against debris contamination. Regular inspection and cleaning of this filter dramatically extends pump life and maintains consistent material flow—a small maintenance step that prevents costly repairs.

Frequently Asked Questions
The 0533591 suction filter is manufactured to the original equipment specifications for the AirCoat 423 system, providing the appropriate mesh size for effective filtration of typical coating materials. The filter is designed to capture particles that could damage pump components or affect finish quality while maintaining adequate flow rates for production spraying.
Routine cleaning with appropriate solvent and a soft brush is recommended for maintenance. However, filters have a finite service life—repeated cleaning can degrade the mesh, and abrasive materials can erode the filtering surface. If the filter shows visible damage, cannot be thoroughly cleaned, or if you're experiencing persistent contamination issues, replacement is the best course of action.
A clogged suction filter restricts material flow to the pump, causing cavitation, pressure fluctuations, and reduced maximum output. This can lead to inconsistent spray patterns, difficulty maintaining prime, and increased wear on pump components. In severe cases, debris may bypass a damaged filter and cause tip clogging or damage to pump packings and valves.
Installation typically involves: 1) Removing the old filter from the siphon tube, 2) Cleaning the tube end, 3) Pushing the new filter securely onto the tube, ensuring it's fully seated, 4) Positioning the filter so it rests near the bottom of the material container without blocking flow, and 5) Testing prime before operation. The filter should fit snugly to prevent debris from bypassing.
