Taco 433-5 Air Scoop 1-1/2 Inch Cast Iron

The Taco 433-5 Air Scoop is a 1-1/2 inch cast iron fitting designed to efficiently remove air from hydronic heating systems. This air elimination device installs directly in the supply line and uses the velocity of water flow to separate entrained air bubbles from the system.

Key Features:

• 1-1/2 inch NPT connection size for compatibility with standard piping
• Durable cast iron construction for long-lasting performance
• Scoop-shaped internal design creates turbulence to capture air bubbles
• Tapped opening on top accepts Taco Vent-Rite air vents or other automatic air vents
• Helps prevent air-related issues like noise, reduced efficiency, and corrosion

Air scoops are essential components in hydronic heating systems, working in conjunction with automatic air vents to maintain proper system operation. The Taco 433-5 installs horizontally in the supply line, typically at the boiler outlet where water temperature is highest and air separation is most effective.
