Every poly spray rig depends on clean, unrestricted material flow to deliver consistent spray performance. While major components like proportioners and heated hoses receive most of the attention, smaller components such as inline filters often make the difference between productive spray days and costly downtime.
One simple upgrade contractors can make is installing an A-Side Inline Filter between the heated hose and whip hose. This small component helps protect spray equipment by capturing debris before it reaches the spray gun, reducing the risk of clogs and helping maintain consistent spray performance.
When an A-Side Inline Filter Can Save You Time and Equipment
If you’ve ever dealt with crystallization in the A-side hose or continued finding debris after flushing the system, you know how frustrating it can be. Even after cleaning the hose, remaining contaminants can continue traveling through the material line and eventually reach the spray gun.
That’s where an A-Side Inline Filter becomes valuable. Installed between the heated hose and whip hose, it helps capture remaining debris before it reaches downstream components, making it an excellent upgrade for contractors troubleshooting contamination issues on a poly spray rig.

When Should You Inspect the Filter?
Like any filtration component, the A-Side Inline Filter should be inspected regularly. Contractors should consider checking the filter more frequently when:
- Starting a new drum of material
- Experiencing reduced spray performance
- Performing routine equipment maintenance
- Working in dusty jobsite conditions
- Troubleshooting inconsistent spray patterns
Routine inspections can help identify buildup before it affects the performance of your poly spray rig.
Preventive Maintenance Helps Reduce Downtime
Unexpected downtime often starts with small maintenance items that are easy to overlook. Keeping filters clean and replacing worn components when necessary helps contractors avoid unnecessary interruptions.
A good preventive maintenance routine also includes:
- Inspecting transfer pumps
- Checking heated hose connections
- Cleaning spray gun screens
- Verifying proper material temperatures
- Inspecting inline filters for contamination
Together, these maintenance practices help keep your poly spray rig operating efficiently throughout the job.
