Ametek USG NL300L Air Volume Control - Shallow Well Operation

Ametek Model NL300L low lead air volume control for shallow well operation. Spec# 148542ANL

Ametek U.S. Gauge air volume controls are designed to maintain the proper ratio of air to water in hydropneumatic tank systems.

The NL300L is designed for shallow well systems where air is admitted through a snifter valve on the pump. When the water level in the tank is high, the float opens a valve allowing air to flow through the inlet of the snifter valve and into the tank. This operation continues until an adequate amount of air enters the tank and the water level lowers. The float then closes the air valve preventing additional air from entering the snifter valve. The optimum relationship of and water in the tank is thus maintained.

U.S. Gauge low lead air volume controls adhere to the “Reduction of Lead in Drinking Water Act”.

HOUSING: Die cast zinc, with 1-1/4 – 11-1/2 ANPT male connection for tank installation, and 1/4-18 ANPT female connection to accept a U.S. Gauge Model P-500LL pressure gauge, 1/4-18 ANPT, LM connection
AIR INLET VALVE: Schrader or Dill type valve is mounted in the hose connection.
TUBING: A 48" length of polyethylene tubing is included.
FLOAT: Plastic bulb, mounted on a solid, low lead brass rod
INTERNALS: A flexible, molded neoprene plug of unique design acts as both dividing wall and fulcrum through which float action is transmitted to the air inlet valve.
