Unit is cleaned using built-in automatic water wash and hand water gun. Waste empties into a tub for easy disposal. VacuVest is warrantied for 1 year against defects, except pouring taps which may wear after extended use. Made in the United Kingdom.

"Prior to purchasing the full vacuum auto-invest unit from Gesswein, we used a conventional bell jar vacuum unit. Our experience with the conventional vacuum unit was that sporadically we would have problems with air bubbles on our castings due to air being trapped in the investment. The bubbles on castings were labor intensive to remove and raised our reject rate.

"Since we began using the unit from Gesswein, we have had no problems with air bubbles being trapped in the investment. The equipment has saved labor and has improved the quality of our castings. In addition we are able to invest more flasks per hour than with the conventional unit. Gesswein's self-contained unit is clean, efficient and well-designed. I would not hesitate to recommend VacuVest to anyone having similar problems with investing."

"We couldn't be happier with our VacuVest #20 from Gesswein. The invested results are excellent – no bubbles! Our operator now has time to do other things as the machine needs very little operator assistance. This feature is extremely important in times of cost cutting and searching for the most efficient methods of operation."
