Astro KB30 Hot Melt Unit

MELTER, KB30, 240V

High Performance Extrusion Melt Unit.  The KB30 Melt Unit supplies hotmelt adhesive for a wide range of manual or automatic packaging, product assembly and other industrial operations. Designed for a variety of applications, the KB30 holds up to 30 lbs. (14kg) of hotmelt in pillow, pellet, slab or bulk form. The cylindrical shape of the Teflon ® -lined melt tank concentrates heat at the bottom while maintaining cool temperatures at the top. This minimizes adhesive degradation and charring to reduce pump, hose and nozzle plugging.

An electric motor driving the positive displacement gear pump pressurizes and feeds adhesive through heated hoses to handguns or automatic heads. The reliable and rugged KB30 is one of  Slautterback's workhorses.
