Commercial & Residential Filtration
Durable Fiberglass Mineral Tanks for Reliable Water Treatment
High-performance pressure vessels engineered for water softeners and backwashing filter systems
Fiberglass mineral tanks provide the structural integrity and chemical resistance needed for demanding water treatment applications. These pressure vessels are specifically designed to house filter media, resins, and other treatment materials in residential and commercial systems.
Key Applications
Where Fiberglass Mineral Tanks Excel
Water Softening Systems
Perfect housing for ion exchange resins in residential and commercial water softeners. Fiberglass construction withstands brine solutions and regeneration cycles without degradation, ensuring years of maintenance-free operation.
Backwashing Filters
Ideal pressure vessels for carbon filters, sediment filters, and catalytic media systems. These tanks handle the pressure fluctuations of backwash cycles while maintaining structural integrity throughout the filtration process.
Industrial Treatment
Robust enough for commercial water treatment facilities, food service operations, and manufacturing processes. Fiberglass composite construction resists corrosion from chemicals that would damage traditional steel tanks.
Selection Guide
Choosing Your Mineral Tank
Determine System Requirements
Calculate your required flow rate, service capacity, and regeneration frequency. Consider peak demand periods and the volume of water your household or facility uses daily to ensure adequate treatment capacity.
Select Appropriate Dimensions
Match tank diameter and height to your media volume needs and available installation space. Common sizes range from 9 inches to 14 inches in diameter, with heights from 35 to 65 inches depending on application.
Verify Connection Compatibility
Confirm that valve threading matches your control system, typically 2.5-inch NPT for residential applications. Check that the tank includes proper base support and pressure ratings meet your system specifications.
Installation Tip: Always place mineral tanks on a stable, level surface and ensure adequate clearance above the tank for valve removal and media replacement. Most tanks require 18 to 24 inches of overhead space for proper servicing.
Superior Corrosion Resistance
Fiberglass composite construction withstands exposure to brine, chlorine, and other treatment chemicals that corrode metal tanks, providing decades of reliable service.
High Pressure Ratings
Engineered to handle operating pressures up to 150 PSI, maintaining structural integrity under demanding conditions throughout the service life.
Wide Temperature Range
Suitable for water temperatures from 35°F to 120°F, accommodating both cold well water and warmer municipal supplies without expanding or contracting.
NSF Certified Materials
All tanks use food-grade, NSF-approved materials that meet strict safety standards for potable water contact — no harmful substances leach into your treated water.
