First-Stage Regulators
First-Stage regulators reduce tank pressure to a lower pressure (usually 10 psig / 0,69 bar) for a Second-Stage regulator. Fisher brand First-Stage regulators are painted
red for easy iden?fi ca? on. Vents are screened with standard orienta? on over the outlet.
Two-PSI Service Regulators
Two-PSI Service regulators serve as an intermediate regulator a? er the First-Stage regulator. These regulators are designed for 2 psig / 0,14 bar LP-Gas regulator
systems. Fisher brand 2-PSI regulators are painted white or are green with white closing caps for easy iden?fi ca? on.
Second-Stage Regulators
Second-Stage Regulators reduce the pressure from a First-Stage unit to 11” w.c. / 27 mbar in domes? c installa? ons. Vents are screened with standard orienta? on over
the inlet; however, other vent orienta? ons are available. Fisher brand Second-Stage Regulators are normally painted palm green for easy iden?fi ca? on.
Integral Two-Stage Regulators

between the building being served and the tank is short. Integral Two-Stage regulators provide all the advantages of Two-Stage regula? on. These units are color
coded gray for easy iden?fi ca? on. Vents are screened with standard orienta? on over the outlet
