Universal Dual Air Gap with Dual 3/8-inch OD Ports (AG100-002, 34800)
  • ❤ FLOW RATE: The AG100-002’s maximum flow rate is 4 gallons per minute (GPM) for each port. The maximum flow rate through an air gap is the highest flow rate at which water does not splash outside of an air gap. At maximum flow rate, the air gap is dry on the outside.
  • ❤ EASY TO CONNECT: The AG100-002 air gap has two 3/8-inch OD inlet port for direct 3/8-inch ID poly tube connection. Both inlets can drain water simultaneously without interfering with each other. Since an air gap is a non-pressurized device, very little pressure is exerted on the tubing connected to the air gap. To minimize the movement of tubes connected to the air gap, it is recommended that tubes are secured to a supporting structure using clamps within 18 inches from the air gap.
  • ❤ STANDPIPE CONNECTION: The AG100-002 air gap inserts directly into the 1-1/2-inch and 2-inch standpipes. The body of the air gap provides stops to assure secure placement. This air gap can be used with plastic or metal standpipes. If needed, it can be glued in place to plastic standpipes using regular PVC adhesive. The air gap outlet is designed to pass up to 8 gallons per minute. The optimum recommended flow rate is 5 gallons per minute.
  • ❤ SPLASH PROTECTION: The AG100-002 air gap uses splash guards to assure a completely dry operation. Splash guards are an integral part of the design and can be seen through the side air gap window. During water softener operation, an initial discharge surge can create splashing. Splash shield eliminates the possibility of water splashing outside of the air gap. When designing drainage for an air gap, makes sure that P-trap is located minimum 20-inches from the top of the standpipe.
  • ❤ QUIET OPERATION: When water exits the air gap, depending on the design, it may flow directly into a P-trap. This can create splashing noise that may be objectionable. To avoid excessive noise, it is recommended to use 22 degrees elbow inline with standpipe to avoid direct drainage to P-trap. The pipe elbow should be located at least 12 inches from the air gap to eliminate splashback. If an elbow is not an option for your application, we can provide a flow deflector.
