Products - Compressed Natural Gas Regulator



The ISF1 is an intrinsically safe, FM approved device that is potted for the direct control of natural gas.

Intrinsically safe means that the electronics or wiring contained within the equipment cannot spark or cannot accumulate enough energy to ignite the gas or vapor at the location. Additionally, the surface temperature of the equipment cannot get high enough to ignite the gas or vapor at the location.

New EPA Rule EPA-HQ-OAR-2010-0505 – Published on August 16th 2012, this rule states that continuous bleed natural gas-driven pneumatic controllers between the wellhead and the gas processing plant must have a bleed rate not greater than 6 SCFH. The gas industry has until October 15, 2013 to comply. The ISF1 complies with a threaded exhaust port than can be routed to and consumed downstream.
