Resideo PV125S Eliminator

For high-efficiency hydronic management, the Resideo PV125S Eliminator provides professional-grade air separation in closed-loop heating and chilled water systems. Engineered with a durable bronze body and a 1-1/4 inch sweat connection, this hydronic air eliminator utilized a patented stainless steel concentrator to aggressively remove micro-bubbles and stagnant air pockets that cause system noise and performance degradation. Unlike standard vents that are prone to leaking, the Resideo SuperVent PV125S features a no-clog vent assembly designed to resist dirt and debris fouling, significantly reducing maintenance intervals for field technicians. With a maximum operating temperature of 240°F and a safe working pressure of 125 psi, this unit ensures reliable gas separation even under demanding commercial or residential loads. The 360-degree adjustable collar ring allows for flexible installation in tight mechanical rooms, while the high-temperature thermoplastic float ensures consistent venting performance without the need for manual bleeding, maintaining optimal heat transfer across the entire loop.

Key Benefits

• High CV Capacity: Delivers a 38 Cv rating for efficient flow management in 1-1/4 inch copper piping systems.
• No-Clog Venting: Specialized assembly prevents mineral buildup and debris from fouling the seat, eliminating common leak points.
• Superior Micro-bubble Removal: Patented concentrator provides up to three times the impact area of competing air purgers for quieter system operation.
• Installer Flexibility: Integrated 360-degree adjustable collar simplifies orientation during sweat connection soldering.
• Corrosion Protection: Removing oxygen and entrained gases preserves the lifespan of radiators, heat exchangers, and circulator pumps.

Common Questions

• Can this be used for solar or high-temp glycol systems? Yes, the 240°F temperature rating and bronze construction are compatible with most standard hydronic glycol mixtures.
• Does the PV125S require periodic bleeding? No, the automatic float mechanism provides continuous venting once the system is pressurized.
• Can the vent top be replaced if damaged? Yes, the top assembly is serviceable and can be swapped using the PV-001RP replacement part without replacing the entire bronze body.
