Product Advantages

• Reliable operation reduces water hammer incidents.
• Dynamic design allows for high capacity air discharge whie preventing premature closing.
• 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.
• Threaded discharge outlet allows connection of additional piping for venting and drainage.
• Body and all operating parts made of high-strength corrosion-resistant composite materials.

Applications

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

• One-Piece Float & Seal Assembly

  Float and seal are enclosed in a one-piece sealed unit with no need for a separate o-ring. It’s easy to remove – just unscrew the threaded float lock and replace with a new unit. No need to replace the complete air vent.
