Electrostatic Spraying Technology

MicroClean uses the latest electrostatic spraying technology to provide superior spray coverage.

What is Air-assisted Electrostatic Spraying?

At the heart of the air-assisted electrostatic sprayer is the patented air-atomizing induction-charging nozzle, which was invented at the University of Georgia.  Air and liquid enter the rear of the nozzle separately. The air moves through the nozzle under pressure and meets the liquid at the nozzle tip, causing the formation of spray droplets that are 30 to 60 microns in diameter. At the tip of the nozzle is a tiny electrode which applies an electrical charge to the spray. The electrical charging causes a natural force of attraction between the spray droplets and target surface, similar to the attraction between items of clothing created by the tumbling of a clothes dryer. The attraction to the target's surfaces relates to Coulomb's Law, which states that any two charged objects will create a force on each other. The charge on the droplets, though small, pulls the spray towards the target at 75 times the force of gravity. The spray droplets can reverse direction, moving against gravity, to coat all sides of an object.

This remarkable phenomenon by which the spray coats the undersides and the backsides of the spray target is known as electrostatic "wraparound". In practical terms, this means that spray reaches the underside, the back side, and nooks and crevasses of the target surface.


Better Coverage - Testing by four major universities comparing the sprayer MicroClean uses with conventional and air-blast sprayers shows 300% better spray penetration and coverage onto hidden areas. 

Less Product Waste - The studies also found that only 15-20% of the spray from conventional or air-blast sprayers ends up on target, with nearly 60% of the product wasted on the ground and less than 3% reaching the underside of the target and other hidden areas.

Environmentally Sound - Using even less of an already low-toxicity product makes the spray environmentally safe and effective. 

    See the difference...

    Both black knobs were sprayed with fluorescent dye. However, the one on the left had the electrostatic system turned on whilst the one on the right did not. The spray coverage is so uneven on the right knob that the back side of the knob remains untouched and is actually able to reflect the evenly-coated electrostatic sprayed knob on the left.
