Spray Gun Reducers

Spray gun reducer is an essential device for setting, lowering, and stabilising the pressure of compressed air from 0.7 to 3.5 bar before it is delivered to the pneumatic paint spraying gun. Typically, an air pressure regulator with a gauge is sold in a set for spray guns.

Which reducer to buy for a paint gun

On the handle

We recommend paying attention to the SA-RM10-08 model (thread ¼ inch). This is an inexpensive and small device with low weight and comes with a gauge, which meets the needs of all paint sprayers with consumption rates up to 700 litres of air per minute.

Most pneumatic tools are equipped with 'male' quick-fittings, so for connecting devices and hoses, we recommend purchasing an additional bronze 'female' coupling and a threaded nipple SF-Z2500 1/4. For example, this way you can connect the reducer to a 1/4 intertool pt-1422 paint gun.

The best choice of regulator for professional painting

If you have a low-output compressor, small receiver, or many consumers, working in a pneumatic system will experience significant pressure fluctuations at the inlet, which a regular regulator cannot smooth out. We recommend considering the purchase of a precision model SA-RP 1/4, which will help to set the pressure very accurately. We wrote about the impact of pressure regulation on painting quality in the article.

What air pressure is required for spray guns?

Depending on the type, pneumatic guns operate at an air pressure of 0.7 to 5 atmospheres. Most spray guns on the market belong to the LVLP or HVLP types. The 'LP' in these abbreviations stands for “low pressure”, meaning low pressure up to 3.5 bar — such pneumatic tools are universal, providing uniformity and fine disperson for applying low-viscosity paints, paint from the nozzle hits a short distance and does not create a 'mist', making them safer. The recommended working pressure is indicated by manufacturers in the instructions and often on the handle.
