The invention is concentrated at the front end of such an air spray or HVLP gun and in particular details the relationship between the exterior of the fluid nozzle and the inside of the air cap. In particular, the fluid nozzle has a generally frustoconical outer surface which forms an included angle of about 50.degree.. The inside of the air passage at its rearward end has an included angle of about 20.degree. and then curves gently to the point where it is adjacent to the front of the air cap to form a domed inner surface.

Domed air cap

A spray gun is easily convertible between a number of configurations. A removable fluid insert may be placed in interchangeable (airspray and HVLP) spray heads with the fluid insert being either a pressure fed device which depends downwardly from the front end of the gun into a pressurized cup or via a connection to a pressurized fluid source or may have an upwardly directed insert which will take fluid from a gravity cup. A simple air swivel also adds ergonomic benefits.
