MEC FULL SIZE AUTO CHANGEOVER REG - 1/4" IF x 1/2" FNPT - 11" WC

These Two Stage Automatic Changeover regulators combine the first and second stage regulator into one unit converting full tank pressure to 11” WC. MEC Excela-Flo™ Automatic Changeover regulators prevent gas outages by switching supply cylinders over to the reserve cylinder automatically when the primary cylinder is near empty. When the primary cylinder is depleted causing the changeover to occur a red indicator will appear signifying the reserve cylinder in now in use and the primary cylinder can be refilled without loss of service.

MEGR-175CS61622-BCF Series offers all of the same features as the compact MEGR-175S61222 series but with a full size high capacity second stage regulator option. The full size second stage diaphragm provides superior downstream regulation and features heavy duty wrench flats and a large 3/4” FNPT tapped drip lip vent to help prevent relief vent blockage. This regulator is perfect for manifolding larger tanks together such as 420 LB cylinders.
