The MAGNETsprayBP offers the same electrostatic spray technology as our original MAGNETspray, but with the ergonomics of a backpack design. The MAGNETsprayBP is perfect for spraying in tight, congested areas or anywhere mobility and freedom of movement are critical factors to maximize productivity. As with our original model, the spray gun relies on compressed air to help push a large plume of charged droplets to a targeted surface. However, for optimum convenience and portability, the MAGNETsprayBP allows the operator to use their own air source. In addition to the spray gun, the MAGNETsprayBP includes a 2.5 gallon tank which is worn comfortably on the operators back and hips and a 100 ft air hose for working large areas without interruption and labor costs.
