00209-VS270 SCULLY VENTALARM TANK FILL SIGNAL 2" X 2" 19719

The Scully 00209-VS270 Ventalarm Tank Fill Signal is a precision-engineered mechanical fill indicator designed for use in fuel storage, chemical, and fluid containment systems. This 2-inch by 2-inch vent and fill signal provides an audible whistle during filling operations, automatically ceasing when the tank reaches capacity. Built for reliability in industrial and commercial applications, the Ventalarm prevents overfilling, tank rupture, and product loss by providing immediate, accurate feedback during transfer operations. Its rugged construction and passive operation ensure long-term service life under continuous duty conditions.
