Electrostatic Mist Blower vs. Air Blast Sprayer

Replying to many questions, here are the most important differences concerning how air is used by the “Martignani-KWH” Mist Blowers and the traditional Air Blast Sprayers

All the air sucked in by the dual intake blower is used Only 2/3rds of the axial fan produces air: 1/3rd of the fan is not used although it requires power

Uniform airflow on all of the outlet section and perfectly directed air stream The air turns around the impeller shaft, causing turbulence and non-uniform air stream at the outlet (the stream in mainly upwards on one side and downwards on the
The special streamlined design of the spray-heads directs the air almost with no loss of power The air must suddenly turn through 90° causing a loss of speed and power of 20%

A continuous air stream of high speed and penetrative power, but without violence and turbulence Heavy turbulence in the air stream causing great loss of speed and power
The two outlets can be turned through 90°, thus for every shape of the tree the air stream can be directed individually to the most important parts of the tree No adjustment or adaptation to the tree shape possible

Both heads can be directed in one direction: this doubles penetration so that perfect coverage is possible also under windy conditions When working one-sided, the liquid output on one side must be
closed, the air capacity of this side will remain unused though power is absorbed

Straight flow air stream and the absence of turbulence gives a high output. Add to this the advantages of the many adjustments possible for single and double-sided spraying – the K.W.H. B 612 can be considered as using 100% of the power required It has a loss of power of 20% and 33% (see points 1, 2, 3) leaving only less than 50% which on the other hand is used inefficiently

DOUBLE AIR ACTION: uniform droplet production and transport of liquid
SINGLE AIR ACTION: only transport of the liquid divided into droplets of different size by the pressure nozzles
