The GM 3000 AC AirCoat gun (air-assisted airless) is built to deliver optimal finishing results while being user friendly. For optimal finishing results, a choice of two air caps matches the gun to the material being sprayed. There is a blue air cap for water based materials and a red air cap for solvent based materials. Additionally, the AirCoat nozzles are manufactured to the highest precision. Improved geometry of the nozzle core helps to reduce nozzle and pump wear. For ease of use, the filter housing of the GM 3000 AC can be opened without the use of tools. There is also a version available without a filter. Additionally, when a nozzle becomes plugged, it can simply be reversed and blown through to clear the obstruction.
