Honeywell PV150/U Air Eliminators, 1-1/2 in, Female NPT, 125 psi, 240 deg F, Bronze

The Honeywell PV150 SuperVent Air Eliminator provides superior air removal for hydronic heating and cooling systems, improving efficiency, reducing noise, and extending equipment life.

Engineered for performance and durability, the Honeywell PV150 automatically eliminates trapped air from closed-loop hydronic systems. Its precision-engineered float mechanism, corrosion-resistant bronze body, and high-temperature capability ensure reliable, maintenance-free operation in both residential and commercial heating applications.

• Model number PV150 designates this Honeywell SuperVent Air Eliminator with a 1-1/2-inch female NPT connection for large-capacity hydronic systems.
• Designed to automatically vent trapped air from water-based heating and cooling systems, preventing air lock, corrosion, and circulation inefficiency.
• Constructed from durable bronze for high strength, corrosion resistance, and long service life under elevated temperature and pressure conditions.
• Compact vertical design allows easy installation in new or existing systems.
