Netafim 2 in. FPT Nylon Combination Air/Vacuum and Continuous Acting Pro Air Vent

PRODUCT FEATURES:

• Reliable operation reduces water hammer incidents
• Threaded discharge outlet allows connection of additional piping for venting and drainage
• Dynamic design allows for high capacity air discharge while preventing premature closing
• Body and all operating parts made of high-strength corrosion-resistant composite materials
• Float and seal assembly are enclosed in a one-piece, easily replaceable unit - independent of the air vent body
• Sealing assembly, with its unique patented rolling seal feature which allows gradual opening, closing and self cleaning, is contained in the one-piece float assembly
• Simple and reliable reinforced nylon body is compact in size and light-weight
• The light-weight feature is ideal for installation on plastic piping systems and other light-weight piping systems

DESCRIPTION OF OPERATION:

• The Pro Air Vent combines the features of both an air release and an air and vacuum vent.
• This air vent will open to relieve negative pressures whenever water column separation occurs.
• The air and vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system.
• The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.

APPLICATION:

• At end lines
• Before water meters
• After deep well pumps
• On strainers and filters
• On long, constant sloped pipeline segments
• Pump stations - after the pump and after the check valve
• Downstream (after) and upstream (before) shut-off valves
• At peaks along the pipeline and at peaks relative to hydraulic gradient
