Description
The Resideo FV147 is a 1/8″ Maxivent automatic air vent engineered to continuously and automatically purge trapped air from hydronic heating and cooling systems. By eliminating air pockets that cause noise, reduced flow, and inefficient heat transfer, the FV147 helps keep your hydronic system operating at peak performance with minimal maintenance.
Key Features
- 1/8″ NPT connection for easy installation into standard hydronic piping
- Automatic float-operated venting mechanism — no manual intervention required
- Compact Maxivent design fits tight spaces in boiler rooms and mechanical systems
- Continuously vents air as it accumulates, preventing airlock and flow disruption
- Durable construction suitable for residential and light commercial hydronic applications
- Compatible with hot water heating systems, radiant floor systems, and chilled water circuits
Why Automatic Air Venting Matters
Trapped air in hydronic systems is a leading cause of noisy pipes, uneven heating, and reduced system efficiency. The Resideo FV147 Maxivent addresses this by providing continuous, hands-free air elimination at high points in the system where air naturally collects. Installing an automatic air vent like the FV147 reduces service calls, extends component life, and keeps your system running quietly and efficiently.
Typical Applications
- Residential and commercial hot water boiler systems
- Radiant floor heating loops
- Chilled water air conditioning systems
- Fan coil unit connections
- Baseboard and panel radiator installations
