Air Pump Installation Kit

The Nelsen Air Pump Installation Kit gathers the essential hardware needed to add or service a compressed-air injection system on iron, manganese, and hydrogen-sulfide treatment setups. Rather than chasing individual fittings across several suppliers, this kit delivers the core components in one convenient package—a pressure gauge, poly tubing, an air regulator valve, a mounting shelf, and a stainless steel check valve—so the air side of the system goes together correctly the first time.

How air injection fits into treatment

Many of the most stubborn well-water problems—rusty iron staining, the rotten-egg smell of hydrogen sulfide, and manganese discoloration—respond best to oxidation. An air pump injects a controlled amount of air ahead of the filter, oxidizing the dissolved contaminants so the media downstream can trap and hold them. For that process to work reliably, the air side of the system needs proper supporting hardware: a gauge to monitor pressure, a regulator to dial in the correct air volume, tubing to route the supply line, a shelf to mount the pump cleanly and securely, and—critically—a check valve to stop water from backing up into the pump and ruining it.

• Pressure gauge for monitoring air-system pressure
• Poly tubing for routing the air supply line
• Air regulator valve to set the injection volume
• Mounting shelf for a clean, secure pump installation
• Stainless steel check valve to prevent backflow
• Approximately 1.14 lb complete Nelsen-brand kit

This Nelsen-brand kit is ideal for installers building an air-injection oxidation system from scratch, and equally useful for homeowners upgrading an existing filter to handle a new iron or sulfur problem. Having the regulator, gauge, tubing, shelf, and stainless check valve matched together in one kit means the installation is done right and the air side stays protected from water intrusion, which is the most common cause of pump failure in these setups. Dialing in the right air volume matters too: too little air starves the oxidation reaction and lets contaminants slip through, while too much can blanket the media and reduce contact, so the regulator and gauge let you tune the system to your specific water chemistry. A properly supported air pump is the difference between consistent, trouble-free oxidation and a system that struggles or fails prematurely—and this installation kit gives you the correct parts to do the job the way it should be done.
