Materials & Finishes: Durable, high-quality construction with customizable exterior and interior coatings, including standard primer, powder coating, enamel, galvanized finishes and epoxy interiors. Select FDA or NSF approved linings are available for food-grade and potable water applications.
Certifications & Compliance: Engineered in full compliance with all industry safety standards and regulations, and backed by a team of technical experts who can help with technical questions and installation support.
Applications & Industry Solutions
Food & Beverage
FDA-compliant linings and steady vacuum reserve keep packaging and filling lines running consistently.
Chemical processing
Galvanized, epoxy and powder-coated finishes resist corrosion, and 150 PSI rating supports vacuum for drying, distillation and evaporation.
Pharmaceutical
Vacuum storage keeps powder conveying and drying processes consistent while reducing pump wear.
Medical & Dental
Compact 30-120 gallon sizes fit easily into clinic and hospital vacuum systems, providing suction with less pump cycling.
Water & Wastewater treatment
NSF-approved potable water linings and galvanized finishes provide durable vacuum storage for water and wastewater systems.

A vacuum tank stores a reserve of vacuum between your pump and your equipment. It absorbs sudden changes in demand, keeps vacuum levels steady, and reduces how often your pump cycles on and off. That means less wear, lower energy use and longer pump life.
Our standard vertical vacuum tanks range from 30 to 1,060 gallons, with diameters from 16 to 48 inches and lengths from 38 to 144 inches. All models are rated to 150 PSI. Need a size outside this range? Our team can build a custom vessel for your application.
