Rain Bird® HE-VAN Series
High Efficiency Variable Arc Nozzles

The ONLY high efficiency variable arc nozzle available today.

Rain Bird HE-VAN nozzles offer even coverage throughout the spray pattern, delivering a healthy, beautiful landscape. Gentle close-in watering eliminates dry spots around the spray head. HE-VAN nozzles also generate large wind-resistant water droplets that prevent misting and airborne evaporation so the right amount of water is delivered to the right place.

The high efficiency of the HE-VAN nozzle allows you to shorten your sprinkler run times by up to 35%, saving you water and money. Even coverage makes them the perfect choice for homeowners looking to conserve water while maintaining a healthy beautiful landscape.

Now available in popular 8', 10', 12’ and 15’ radii, HE-VAN nozzles also offer matched precipitation with Rain Bird® MPR and U-Series nozzles.

Save Water and Money

HE-VAN’s even coverage reduces run times by up to 35% while still maintaining a healthy lawn.
Just like changing to a low-flow shower head, homeowners can save water by upgrading to HE-VAN nozzles.

Superior Coverage

HE-VAN nozzles have a unique stream pattern, designed for superior coverage and wind resistance.
Other nozzles produce un-even edges and throw water past the stated radius. HE-VAN nozzles throw to the exact specified radius for the cleanest edge of any VAN on the market today.

Upgrade Example

The material cost to upgrade a typical 8 spray zone to HE-VAN is less than $13.52.
Per the example below, HE-VAN nozzles can save 17,672 gallons of water per year. That’s a 30% savings!

HE-VAN-08 High Efficiency Variable Arc Nozzle 6-8 foot throw radius	HE-VAN-10 High Efficiency Variable Arc Nozzle 8-10 foot throw radius
HE-VAN-12 High Efficiency Variable Arc Nozzle 10-12 foot throw radius	HE-VAN-15 High Efficiency Variable Arc Nozzle 12-15 foot throw radius

Efficiency Ratings

Rain Bird HE-VAN Nozzles deliver an average DU_LQ of 70%, more than a 40% improvement over typical variable arc spray nozzles.
Rain Bird HE-VAN Nozzles deliver a SC less than or equal to 1.6, which is 35% lower than the typical variable arc spray nozzle.

Distribution Uniformity (DULQ): DU in irrigation is a measure of how uniformly water is applied to the area being watered. DULQ is calculated by taking the volume in the lowest quarter of catch can measurements and dividing it by the average volume of all catch can measurements. Scheduling Coefficient (SC): SC is a measure of how long a zone must be run in order to provide adequate water to the driest spot.

Operating Range

Radius:

HE-VAN-8: 6 to 8 feet (1.8 m to 2.4 m)

HE-VAN-10: 8 to 10 feet (2.4 m to 3.0 m)

HE-VAN-12: 10 to 12 feet (3.0 m to 3.7 m)

HE-VAN-15: 12 to 15 feet (3.7 m to 4.6 m)

Pressure: 15 to 30 psi (1.0 to 2.1 bar)

Optimum Pressure: 30 psi (2.1 bar)

These ranges are based on proper pressure at nozzle. Rain Bird recommends using 1800 PRS Spray Bodies to maintain optimum nozzle performance in higher pressure situations
