Scully VS-220 1-1/4" Compression Ventalarm Tank Fill Alarm Signal

The Scully VS-220 Compression Ventalarm is designed for existing installations, allowing you to install the fill alarm without removing the existing vent pipe using a special leak-proof fitting that requires no threading or additional fittings. This audible tank fill signal is used with above-ground tanks to stop costly spills and prevent ruptured tanks, with the whistle stopping when the tank has been filled to its safe capacity level.

Key Features:

• 1-1/4 inch tank opening and 1-1/4 inch vent pipe size (Part Number 00203)
• Calibrated whistle stems allow for product expansion
• Patented screen keeps whistle chamber free from pipe scale and bugs
• Installs without removing the existing vent pipe
• Stops costly spills and prevents ruptured tanks while improving delivery efficiency with completely reliable and accurate performance, with one-time installation usually outlasting the life of the tank

Since 1936, Scully Ventalarm has been the original tank fill alarm for spill-free deliveries. Note: Compression Ventalarm signals are not for use in underground tanks. A compatible gasket kit (Part Number 10266) is available separately for the VS-220 model.
