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.

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.
