Fill Port Tanks with 2.5" Opening

A fill port tank is a fiberglass-reinforced pressure vessel designed to hold filtration media used in water treatment and purification systems. The tank features a top-mounted fill port opening that allows for the easy loading, replacement, and maintenance of filter media such as Calcite and Corosex.

Purpose

• Houses filtration or treatment media in residential, commercial, and industrial water treatment systems.
• Provides a durable, corrosion-resistant vessel for long-term operation in pressurized water systems.
• Allows convenient media loading and servicing through the fill port opening.

Typical Specifications

• Tank Material: Fiberglass-reinforced plastic (FRP) with polyethylene inner liner
• Color: Natural fiberglass (light green or beige) or black
• Configuration: Vertical pressure vessel with top fill port
• Operating Pressure: Up to 150 psi (10.3 bar)
• Operating Temperature: 34°F to 120°F (1°C to 49°C)
• Fill Port Size: 2.5"
• Tank Diameter: Common sizes range from 8" to 36"
• Tank Height: Common sizes range from 35" to 72"
• Base: Molded or separate high-impact plastic base

Features

• Corrosion-resistant construction
• Lightweight yet high-strength design
• Smooth internal liner for media containment
• Compatible with standard control valves and distributors
• Easy media filling and replacement through the fill port
• Suitable for potable water and industrial water treatment applications

These tanks are commonly used as the primary media vessel in water filtration systems where reliable performance, ease of maintenance, and resistance to corrosion are required.
