This airbrush system is designed for heavy-duty use by cake decorators, to add finishing touches to cakes or create airbrushed masterpieces. The compressor is of a constant airflow type, which means the user merely adjusts the flow of colour by a slight backward movement of the airbrush trigger. It has a bleed control valve which allows the user to select the desired airflow from 10 - 30 PSI: from low pressure for very delicate work such as fine lines and delicate shading to higher pressure for a large overall spray pattern. A built-in air accumulator tank eliminates pulsation. The compressor is sturdy, clean, and quiet, and is fully enclosed. The professional quality, single-action, gravity-fed airbrush has a small colour cup to hold your airbrush colour and gravity feed it into the flow of air when you pull back on the trigger. A special crown cap reduces clogging and splattering.
