About Paint Tanks and Pressure Pots
A pressure pot (AKA pressure tank) is a precision painting tool and is typically used for customizing and fine tuning paint spray to meet desired texture results or job specs. The tank holds the paint and the desired spray is achieved by balancing liquid pressure via a liquid regulator, with air pressure via an air regulator. Both regulators sit atop the tank lid. Set fluid pressure, then set air pressure. Increasing air pressure and/or lowering fluid pressure will result in smaller particles of paint for a finer spray. Products differ by capacity, number of regulators and tank composition, among other considerations.
