Produces smooth, crisply detailed molds which result in better castings. Also helps keep dust out of the air for a healthier workspace.

Easy to use and clean: place flasks in vacuum chamber, swivel mixing unit over it, pour water and investment into mixing unit, seal lid and run machine; when done, swivel mixing unit over wash basin and clean out with water gun. Includes two all-metal stands for flexibility. Requires 10 CFM vacuum pump (see "Related Products" below).
