How can RAMVAC possibly improve on something as simple, strong and chemical resistant as our successful line of fiberglass dental vacuum separation tank? For a start, we applied the innovative flat-sided "Box" tank design to make sure the tanks tuck tight into corners and hug flat walls. Then we selected an advanced, high-strength, corrosion-proof polymer, shaped by high accuracy, automated molding. We placed the tank fittings where they’re easiest to get at and we supported the whole works with a sturdy "trucker-proof" steel frame, cut by computer controlled lasers, and designed to allow for drain plumbing flexibility. Construction Non-corrodable polymer Available in 15 or 30 gallon capacity Extra large drain valve Strength Tested to 18" Hg Ribbed Construction Steel "Trucker Proof" side supports
