Anti-icing Vent Skirts
American Gas, March 2001
Bennett Regulator Guards Inc. manufactures a line of patented anti-icing vent
skirts designed to reduce the probability of ice formation on the relief vents
of gas pressure regulators.
The new Meter Bar vent skirt protects a wide variety of meter bar regulators
with ¾-inch NPT threads. Meter bar regulators are
positioned with their vents directly above the meter, allowing minimal clearance
and in the 6 o’clock position. Once the vent skirt is installed, the surface
area around the vent increases from 1 square inch to 15 square inches. The shape
of the vent skirt shelters the relief vent opening and prevents precipitation
from accumulating on the vent it self, says the company. The vent skirt al so
shelters surfaces of the meter to pre vent splashes from reaching the vent, the
maker reports.
