Micronair offer a choice of wind or electrically driven atomisers specifically developed for helicopters. The AU6539 electrically driven atomiser is recommended for operations requiring a low or variable airspeed that would make it difficult to maintain the correct rotational speed with wind-driven atomisers.
Micronair offer a choice of wind or electrically driven atomisers specifically developed for helicopters. The AU6539 electrically driven atomiser is recommended for operations requiring a low or variable airspeed that would make it difficult to maintain the correct rotational speed with wind-driven atomisers. Mounting clamps are supplied with the atomisers and are available for a wide range of round and streamline section spray booms. In addition to atomisers developed specifically for helicopters, Micronair AU5000 atomisers can be used on helicopters operating at higher airspeeds. See Micronair Product Selection Guide for further details.
Light weight and low power requirement
Micronair atomisers are designed for light weight and low drag to minimise their effect on helicopter performance. The AU6539 uses a highly efficient electric motor to give maximum output whilst keeping the electrical power consumption within the sometimes limited capability of small agricutural helicopters.
Droplet size control
The unique benefits of rotary atomisation ensure that where required a maximum number of low-drift droplets are created. However, where an operator requires application equipment suitable for drift spraying (for example in locust or migrant pest control), the unique flexibility of Micronair atomisers offers operators the ability to create smaller droplets as required. At all rates of application the Micronair helicopter range of atomisers allows the operator to control the droplet size to a very narrow spectrum. The droplet size is varied by adjusting the rotational speed of the atomiser. This is achieved by means of an optional electronic speed controller for up to six AU6539 atomisers.
Cost effective
In an industry where time is money, the benefits of increased work rates through accurate and effective application can quickly be realised from reduced flying time.
Precise flow control and liquid shut-off
The flow to each atomiser is controlled by a variable restrictor unit (VRU). This provides finger-tip control of the flow by the simple turn of a knob and eliminates the need to dismantle or change individual restrictor orifices. Overall flow from the helicopter is regulated by the boom pressure in exactly the same way as a conventional spray system. Every atomiser is supplied with a diaphragm check-valve to ensure immediate shut-off of chemical at the end of each spray run.
