Products Description
The 2.5'' FRP Pressure Vessel is a compact fiberglass pressure tank designed for small-scale water treatment and RO pre-filtration systems.
The "2.5 inch" refers to the 2.5'' threaded opening, usually with a top opening design.
A top & bottom opening configuration is also available based on system layout.
This product series includes multiple standard models, ranging from 817 to 1665, with vessel volumes from 11.3 liters to 186 liters.
It is manufactured and supplied by Xi'an Ink-blue Environmental Protection Technology Co., Ltd., specializing in FRP pressure vessels for global water treatment applications.
Key Technical Characteristics
- Opening size: 2.5 inch, threaded
- Material: FRP outer shell + food-grade PE inner liner
- Capacity range: 11.3 L – 186 L
- Flow rate range: 0.1 – 4.5 m³/h
- Typical applications: RO pre-filtration, small filtration units, water softening
Key Features & Advantages
✅ Space-Saving Compact Design
- 2.5" Top Opening: Fits through narrow doorways and under counters-ideal for retrofitting existing small systems (e.g., replacing rusted steel tanks in tight utility rooms).
- Lightweight (8-35kg): 60% lighter than stainless steel tanks, reducing installation labor and ceiling/wall mounting stress.
✅ Corrosion & Chemical Resistance
- FRP+PE Lining: Withstands acids (pH 2-12), alkalis, and chlorine-safe for use with activated carbon, ion exchange resin, and quartz sand.
- No Rust or Leaks: Eliminates metal tank issues like rust contamination and pinhole leaks, ensuring pure pre-filtered water for RO membranes.
✅ Easy Maintenance & Fast Media Replacement
- Top-Loading Design: Open-top lid allows quick media refills (e.g., replace 20kg quartz sand in 5 minutes vs. 30 minutes for side-port tanks).
- Clear Volume Markers: External level indicators prevent over/under-loading of filter media, optimizing filtration efficiency.
✅ Stable Performance for Small Systems
- 0.6MPa Working Pressure: Handles standard RO pre-filtration pressure without bursting (common with plastic tanks).
- 49℃ Heat Resistance: Safe for warm water applications (e.g., laboratory rinse water, small-scale beverage processing).

Compatible Accessories
The 2.5'' FRP pressure vessel is compatible with:
- Automatic control valves
- Manual multiport valves
- Top or bottom distributors
- Central riser tubes
- Upper and lower strainers
These accessories allow plug-and-play system assembly.
Typical Applications
2.5'' FRP pressure vessels are widely used in:
- Small RO pre-filtration systems
- Drinking water treatment equipment
- Laboratory water systems
- Hotel room filtration units
- Water dispensers and kiosks
For large RO or industrial systems, vessels with 4'', 6'', or 8'' openings are recommended.
How to Select the Right Model?
Low flow RO pre-filter → 817 / 844
Office or commercial softening → 1054 / 1252
Higher flow compact systems → 1354 / 1465 / 1665
Media type, system pressure, and flow rate should be considered together.

FAQ
How do I choose the right model for my system?
A: Calculate your flow rate requirement (e.g., 50L/h) and media type:
- Sand/carbon pre-filtration: Choose 817 (0.1-0.3 m³/h) for small RO systems (≤ 500 GPD).
- Ion exchange resin: Opt for 1054 (0.6-1.5m³/h) for water softening in offices.
Can It Be Used Outdoors?
A: Yes. The UV-resistant FRP exterior withstands sun exposure and rain, making it suitable for outdoor small drinking water stations.
What's The Difference Between 2.5'' And 4'' Vessels?
A: 2.5'' vessels are for small flow rates (≤4.5m³/h) and tight spaces; 4'' vessels (e.g., our 2472 FRP Vessel) handle larger systems (6-8m³/h).
How To Prevent Media Channeling (Uneven Flow)?
A: Use the recommended media loading (e.g., 20kg sand for model 817) and install a distributor plate at the bottom to ensure uniform water flow.
What's The Warranty?
A: 3-year warranty on material defects, plus free replacement O-rings for the first 2 years.
