Description
Netafim™ — AUTOMATIC CONTINUOUS ACTING AIR VENTS
PROVEN DESIGN PROVIDES MORE AIR RELEASE CAPACITY THAN OTHER VENTS OF SIMILAR SIZES
PRODUCT ADVANTAGES
- Ensures maximum protection of irrigation system with proper sizing and placement.
- Aerodynamic 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 reinforced UV protected nylon – no metal parts to rust or corrode, no need for spare parts.
APPLICATIONS
1” & 2” COMBINATION AIR/VACUUM AND
CONTINUOUS ACTING AIR VENTS
- For discharge and intake of large volumes of air at pump and filter 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 & 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.
¾” & 1” AUTOMATIC CONTINUOUS
ACTING AIR VENTS
- For high spots where air accumulates.
¾” & 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.
