The Model #900 is an automatic 2-part mixer specifically built for TechKit packages, adhesives and sealants. The mixer is built with an automatic timer which will shut the motor off when the predetermined amount of time expires. The operator attaches the cartridge of material to be mixed by engaging the spindle pins into the dasher rod holes. When the timer is set to material manufacturer’s mixing instructions, and switch is turned to “MIX” position, the Model #900 Automatic Mixer will rotate and actuate the missing blade inside the cartridge automatically. The Model #900 Automatic Mixer eliminates operator fatigue and ensures a more consistent mix of material each time. The Model #900 Automatic Mixer has a smooth, quiet, high quality induction motor.
