Eko3’s Hi-Rate permanent media filtration systems are designed with the intention of establishing higher standards for the commercial recreational water industry- standards associated with water treatment equipment efficiency, water quality, product quality and ease of installation and operation.

Design considerations provide for:

  • Pure and safe water production - safeguarding the health of patrons and employees.
  • Guaranteed performance and systems optimization through automated operation.
  • Reduced operating costs and conservation of natural resources.
  • System performance documentation.
  • Protection against systems malfunction through the use of an alert system.
  • Maintenance minimization and extended equipment life.
  • Easy and affordable installation in both new and retrofit applications.
  • Return on investment planning support.

We are pleased to bring you systems that will meet your needs for decades to come. Eko3's filtration systems exceed all of the product design criteria previously established. Many system features are unique to our product offerings and, therefore, are not found in competitive products. Features of the Hi-Rate permanent media filtration systems include:

Strict Fabrication Requirements

Assembly line productions allow us to offer pre-engineered filtration systems that have consistent quality at affordable prices. Investment in the appropriate tools and fixtures allows us to pressure test, flow test and operate all system components prior to packaging them for shipment - assuring owner satisfaction with every filtration system.


Eko3 provides a superior filtration system for use in the recreational water industry. Cutting edge technology has been employed to provide an efficient and functional system with the highest degree of structural integrity. The unit's high-pressure filter tank, available in three inside diameters 34, 42 and 60 inch, allow for flexibility of the end-user's needs. There is no internal liner or bladder to rupture or cause leaking, no metals, no coating to crack and fail, and no bulkhead fittings to crack and leak. Our filter tanks are designed to be completely integral, using fiberglass, Kevlar and resin construction.

Features of our high-pressure vessels are:

- Polyurethane resin

- Fiberglass strands and roving
- Kevlar
- Non-corroding tank support saddles

Internal Components

All internal components are made of industrial grade non-corroding material, Schedule 80 PVC, polypropylene, ABS and stainless steel.

Air Relief Systems

Internal and external air relief systems

Filter Media
