Combination Air Vents

 
Combination Air/Vacuum and Continuous Acting Air Vents proven design provides more air release capacity than other vents of similar size.

Applications

  • 1″ and 2″ Combination Air/Vacuum and Continuous Acting Air Vents
    • For discharge and intake of large volumes of air at pump and filtration stations, along mains and at the end of mainlines.
    • For continuous air release at high points in pipe network or upstream of manifolds.
    • Every 1,500 feet along mainlines.
  • 2″ Combination Air Release/Vacuum Guard and Continuous Acting Air Vent
    • Releases air at pump priming and maintains the prime by not allowing air intake in long and/or undulating suction lines to pump stations.
    • Releases entrapped air while ensuring continuous prime at centrifugal pumps.
    • Builds up siphons with air release, maintains the siphon by continuously releasing air and not allowing air intake.
  • 3/4″ and 1″ Automatic Continuous Acting Air Vents
    • For high spots where air accumulates.
  • 1″ Continuous Acting/Vacuum Guard Air Vent
    • For release of entrapped air while ensuring continuous pump prime with no air intake in centrifugal pumps and pump suction lines.
    • Protects mechanical seals in vertical pumps by not allowing air to accumulate in the stuffing boxes.
    • Maintain siphons with continuous air release while not allowing air intake.

Product Advantages

  • Ensures maximum protection of the irrigation system with proper sizing and placement.
  • Aeordynamic float design ensures vent closure as water fills the system, remains open when air pressure reaches 12 psi.
  • Large capacity vents dampen water hammer preventing pipes and fittings from cracking or bursting.
  • Unique rolling seal feature allows gradual opening, closing and self-cleaning.
  • Made of corrosion-resistant UV protected nylon – no metal parts to rust or corrode, no need for spare parts.

Specifications

  • 1” and 2” Nylon Combination: 250 psi
  • 1” and 2” Nylon Combination: 150 psi
  • 3/4” and 1” Automatic: 250 psi
