The Multi-Clean 421650 E-Spray Backpack Electrostatic Sprayer offers unsurpassed uniformity in coverage of complex surfaces with exceptional transfer efficiency (minimal over-spray) for disinfectanting, sanitizing, and odor counteracting. Use the electrostatic back sprayer to get the most out of your chemical application. The E-Spray System’s charged droplets reduces overspray and airborne mist.

How It Works:

The battery- The 421650 electrostatic backpack sprayer features a 16.8 Volt Lithium-Ion Battery. This 3400mAh battery will supply 4 hours of run time. Snap align the grooves of the battery into the charger and when the battery is finished charging push it into place in the front of the unit and secure the door by turning it clockwise.

The tank- This backpack sprayer is fitted with a removable 2.25 gallon tank. To remove, pull the handle lock towards the front of the unit, loosening the tank and push back again towards the back of the unit and you will be able to pull the tank off the unit. Reattach the tank by aligning the base of the tank into the base of the unit, pull the handle lock towards the front of the unit so the handle catches the groove at the top tank, secure in place by snapping the handle back into place.

The nozzle- This unit features a 3-way adjustable nozzle. The nozzle has settings for 40, 80, and 110 microns allowing the user to adjust the micron size based on the dwell time desire. To rotate the nozzle, insert the wrench into the nozzle end of the unit and rotate clockwise, the nozzle will click when the next micron size is properly in place.

The hose- To attach the hose at the connections both on the backpack unit and the wand, the larger quick-release connections simply snap on the corresponding receivers, and the smaller connection mechanisms require the metal release on the hose to be aligned with the molded guides on the receiver on the wand/unit.

Power- LED lights along the front left side of the backpack unit indicate the amount of charge the backpack has remaining. When the lowest LED turns red that indicated there is only 20% of battery left.
