Aprilaire 4280 Shock Arrestor
The Aprilaire 4280 Shock Arrestor is a high-performance water hammer suppressor engineered specifically for residential and commercial HVACR applications. This inline water shock absorber is the primary defense against the damaging effects of water hammer, which occurs when solenoid valves close rapidly, causing pressure spikes and loud pipe vibrations. Optimized for 1/4-inch O.D. copper or plastic tubing, this plumbing surge protector stabilizes line pressure and prevents long-term damage to your humidifier or water filtration system. To ensure maximum efficiency, the Aprilaire 4280 should be installed within two feet of the water inlet solenoid valve. By absorbing the kinetic energy of moving water, it eliminates the "banging" noise and protects delicate internal components from high water pressure surges. How do I stop my humidifier pipes from banging? Installing this Aprilaire 4280 Shock Arrestor is the most effective solution. Where should a shock arrestor be installed? It must be placed as close to the valve secondary as possible. Does this work with RO systems? Yes, it is compatible with most 1/4-inch supply lines.
Key Benefits
- Eliminates Pipe Noise: Specifically designed to stop the loud hammering sounds caused by fast-acting humidifier solenoid valves.
- System Protection: Acts as a pressure-absorbing cushion to protect plumbing joints and valve seals from hydraulic shock.
- Simple Technical Installation: Easily integrates into existing 1/4-inch water lines by cutting the line and inserting the device.
- Universal Compatibility: Works seamlessly with Aprilaire humidifiers and other HVACR equipment requiring a water hammer arrestor.
- Compact Engineering: The small footprint allows for installation in tight spaces near furnace or air handler water inlets.
Common Questions
Is the Aprilaire 4280 required for all humidifier installations? While not required for every home, it is highly recommended in systems with high water pressure or where solenoid-induced noise is audible through the plumbing.
Can I use this on 3/8-inch tubing? No, this model is precision-engineered for standard 1/4-inch tubing commonly found in HVACR water feeds.
How far from the solenoid can I mount the arrestor? For peak performance, it should be mounted within 24 inches of the valve to catch the pressure wave immediately.
