FAQ

What types of fluids are compatible with the AJR-0511?

The AJR-0511 is constructed from chrome-plated brass and stainless steel components, making it compatible with a wide range of fluids, including water-based paints, inks, dyes, light oils, and some low-viscosity adhesives. Always check fluid compatibility with the wetted parts before use.

What is the difference between the cylinder air input and the atomization air input?

The cylinder air input (10-32 thread) controls the internal piston that opens and closes the fluid needle. This triggers the spray on and off. The atomization air input (1/8 inch NPT) provides the air that mixes with the fluid at the nozzle to create the fine spray pattern. They are controlled independently for precise timing and spray quality.

How do I adjust the spray pattern and fluid flow on this model?

Fluid flow is adjusted by turning the knurled knob at the rear of the gun, which limits the travel of the fluid needle. The spray pattern’s fineness is controlled by adjusting the atomizing air pressure; higher pressure typically results in a finer mist.
