Air Mic System For Liquid Paint - How an Air Mic System Works 1. Paint Delivery - The paint is delivered to the spray gun under high pressure (typically between 500 and 2000 psi) by a pump. - This high-pressure paint is forced through a small orifice in the spray tip, creating a fine spray. 2. Air Assistance - Compressed air is introduced at the spray gun tip to shape and further atomize the paint particles. - The combination of high-pressure paint and air assistance produces a fine, controllable spray pattern. 3. Spray Gun Configuration - The spray gun is equipped with an air cap and fluid tip designed for precise control over the spray pattern. - Adjustments can be made to control the width and density of the spray.
