1/4 In Precision Air Regulator , 14 cfm Max. Flow (Regulators) is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Our paint operation air pressure to gun was flucuating with a standard regulator causing painting problems - Installed this precision air regulator and problem seems to have been eliminated. Can now hold steady air pressure at low psi.
