Scully VS-230 Ventalarm Tank Fill Signal 1-1/4" 90 Degree Elbow

The Scully VS-230 Ventalarm Tank Fill Signal is an audible alarm system designed for oil tank installations requiring a 90-degree elbow configuration. This whistle-stop device provides reliable overfill protection for both above-ground and below-ground storage tanks by creating an audible alert during the filling process.

How It Works: The Ventalarm whistles continuously while the tank is being filled. When the whistle stops, the tank has reached its safe capacity level, preventing costly spills and ruptured tanks. This simple yet effective system has been trusted since 1936 for spill-free fuel oil deliveries.

Key Features:

• Designed for 1-1/4" tank opening with 1-1/4" vent pipe in 90-degree elbow configuration
• Calibrated whistle stem allows for product expansion and may be cut for flat-style tanks
• Patented screen design keeps whistle chamber free from pipe scale and debris
• Durable construction designed to outlast the life of the tank

The VS-230 model is specifically engineered for installations where space constraints require a 90-degree elbow fitting. This configuration allows for proper installation in tight spaces while maintaining the same reliable overfill protection that has made Scully the industry standard for tank fill alarms.
