Product Advantages 

  • Ensures maximum protection of the irrigation system with proper sizing and placement.
  • Hydrodynamic float design ensures vent closure as water fills the system, remains open when air pressure reaches 10 psi (other vents close quickly when air pressure reaches 3 psi).
  • Large capacity vents dampen water hammer preventing pipes and fittings from cracking or bursting.
  • Unique patented rolling seal feature allows gradual opening, closing and self-cleaning - available on 1" and 2" Combination and 1" Automatic..
  • Made of corrosion-resistant fiberglass with reinforced UV protected nylon - no metal parts to rust or corrode, no need for spare parts.


Application


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.


Specification

Maximum operating pressure:

  • 2" Polypropylene Combination: 150 psi


Stages of Operation


Combination Air/Vacuum Relief and Continuous Acting Air Vents

  1. During start-up, the vent releases large volumes of air.
  2. As the system builds pressure, the body fills with water, forcing the float upwards and closing the vent.
  3. While the system is pressurized, the "automatic" function continuously expels accumulated air.
  4. At shutdown, the vent’s large opening allows air back into the system preventing the pipe and accessories from collapsing, and preventing suction of mud and debris.
