Spray Gun Terms
FEED – Method used to bring material into the gun for spraying.
PRESSURE FEED – Method of material feed where a canister or paint tank is pressurized to force material to the gun. Either internal or external mix air caps are used with this method. Pressure feed is generally used for
spraying heavy bodied materials or for large size projects.
SIPHON FEED – Method of material feed where atmospheric pressure creates a partial vacuum to siphon material to the gun. Only external mix air caps are used with this method. Siphon feed is used with light bodied materials.
GRAVITY FEED – Method of material feed similar to the siphon feed method. However, the cup is inverted to create a positive fluid pressure at the nozzle.
MIX – The mixing of material and air when spraying.
INTERNAL MIX – Process where the air and material are mixed inside the air cap just before being sprayed. This method is best for heavy bodied, slow drying materials and can only be used with the pressure feed method. Do not use fast drying materials with internal mix. The material will dry inside and quickly clog the air cap.
EXTERNAL MIX – Process where the air and material are mixed just after leaving the nozzle. This type of mix should be used for fast drying materials and when a high quality finish is needed.
BLEEDER – In this mode, air passes continuously through the gun whether spraying or not. This mode is generally used when the air is supplied by a continuously running compressor that does not have a tank.
