What types of spray gun washers are available, and what are their primary differences?

Spray gun washers range from manual solvent tanks to automated cleaning systems. Manual solvent tanks, like some Uni-Ram models, typically involve hand-washing parts in a solvent bath. Automated washers, such as those from Herkules, use pumps and spray nozzles to clean guns internally and externally, often with a timer for consistent cleaning cycles. Some units are designed for solvent-based paints, while others are optimized for waterborne paints, requiring different cleaning solutions and sometimes incorporating a drying cycle.

What type of cleaner should I use in my spray gun washer?

The correct cleaner depends on the type of paint you're using. For solvent-based paints, use a compatible gun wash solvent. For waterborne paints, you'll need a waterborne-specific cleaner like Uni-Ram's Aqua-Kleen PGC. Using the wrong cleaner can lead to ineffective cleaning or even damage to your spray gun. Always consult your paint and spray gun manufacturer's recommendations for approved cleaning solutions.

How often should I change the solvent or cleaning solution in my spray gun washer?

The frequency of changing the solvent or cleaning solution depends on usage and the type of paint being used. Regularly inspect the cleanliness of the solution. If it becomes heavily contaminated with paint residue, it's time for a change. Some washers use filtration systems, like the Uni-Ram Coag-Kleen FP Secondary Filter Bag, which can extend the life of the cleaning solution by removing solid contaminants. Always follow the spray gun washer manufacturer's guidelines for solvent/solution replacement.

What maintenance is required for a spray gun washer?

Regular maintenance ensures optimal performance and longevity. This includes regularly changing the cleaning solution or solvent, cleaning or replacing filters, and inspecting hoses and connections for leaks or damage. For automated washers, check the pump for proper function, perhaps using a replacement pump like the AES Industries 39760-1 if needed. Also, ensure the spray nozzles are clear and unobstructed. Refer to your specific washer's manual for detailed maintenance schedules.

Are there any safety precautions I should take when using a spray gun washer?

Yes, safety is paramount. Always wear appropriate personal protective equipment (PPE), including gloves and eye protection, when handling solvents or cleaning solutions. Ensure the washer is located in a well-ventilated area to avoid inhaling fumes. Properly dispose of used solvents and cleaning solutions according to local regulations. Never use flammable solvents near open flames or sources of ignition. If using an automated washer, ensure it's properly grounded.

Can I use a spray gun washer designed for solvent-based paints with waterborne paints, or vice versa?

It's generally not recommended to use a solvent-based washer for waterborne paints, or a waterborne washer for solvent-based paints, without thoroughly cleaning and converting the system. The cleaning solutions are different, and cross-contamination can lead to issues like paint defects. Dedicated waterborne washers often have features like air lines for drying that solvent washers lack. Always check the manufacturer's recommendations for your specific washer model.

What are liner bags used for in spray gun washers, and are they necessary?

Liner bags, like the Uni-Ram LB900C-10, are used to line the waste containers of spray gun washers. They simplify the disposal of paint sludge and contaminated solvent, preventing mess and making cleanup easier. While not strictly necessary, they significantly reduce the time and effort required for maintenance and help keep the washer clean. They also aid in proper disposal of hazardous waste.

How do filtration systems in gun washers work, and why are they important?

Filtration systems, such as those using the Uni-Ram Coag-Kleen FP filter bags, remove solid contaminants from the cleaning solution in a gun washer. This extends the life of the solvent or cleaner, reduces the frequency of changes, and ensures that the cleaning solution remains effective. By removing paint particles, filtration also helps prevent clogs in the washer's pump and spray nozzles, maintaining optimal performance.
