EZ Clean filtration systems featuring the ZGF Spring Filter element

ZGF EZ Clean filtration systems (Phoenix and EC Series) are the most advanced, best in class, automatic, non-disposable liquid filtration systems.  All EZ Clean filtration systems utilize the ZGF Spring Filter element.  The ZGF Spring Filter element is a 316 stainless steel coil wound with a variable pitch that allows the filter element to open evenly from top to bottom ensuring that all contaminants are completely removed from the filter element with each backwash.  The Spring Filter is manufactured with precision raised “nidges”.  These nidges create an absolute gap that allow the Spring Filter to capture > 99% of spherical particles larger than the micron rating of the filter element.  A normal coil does not open evenly from top to bottom, causing ineffective cleaning.  The full opening of the Spring Filter allows lodged or wedged particles to be easily removed as the gap is increased.  While in backwash, the fluid flowing in the reverse direction causes the coil to open and shimmer which further enhances the cleaning capability of the backwash process.  Click on the Spring Filter animation to see the basic principle of operation.  To see the Spring Filter in action, click on the Spring Filter video. See the coil open and shimmer and the contaminants disappear!

The ability of the Spring Filter to open uniformly along its entire length during backwash provides three distinct benefits not achievable by automatic backflushing filters with fixed geometric screens (i.e. wedge wire, etc.).  The benefits are as follows:

  1. Particles wedged or lodged are quickly released and washed away as the gap is increased / opened.
  2. Fluid flowing in the reverse direction causes the coils of the filter element to “shimmer” which further enhances the cleaning process.
  3. Fixed gapped filters do not allow enough fluid to flow in a reverse direction through a dirty filter, particularly at micron ratings less than 100.  The ZGF Spring Filter, while open, allows increased fluid to flow in a reverse direction, providing the fluid necessary for effective cleaning.  No high-pressure nozzles, scrapers, or motors required for cleaning.

The ZGF Spring Filter offers many advantages when compared to disc filters too!  

ZGF Spring Filter technology versus a disc filter

ZGF Spring Filter

Disc Filter

Advantage

316 Stainless Steel

  • More durable – virtually zero maintenance
  • 5-year warranty
  • Consistent filtration – doesn’t wear over time

Plastic

  • Not durable
  • Planned and un-planned maintenance
  • Subject to erosion wear resulting in inconsistent filtration
  • Real and perceived drawbacks of plastic

ZGF Spring Filter

Continuous Coil wound with a variable pitch

  • Opens uniformly and shimmers during backwash to ensure complete removal of debris
  • Returns to clean differential pressure after backwash (100% removal of debris with each backwash)

Individual discs

  • The discs operate independently and are subject to systematic fouling / clogging
  • “Clean” differential pressure increases over time / backwash frequency increases
  • Individual discs can get lost or damaged when removed for cleaning resulting in inconsistent filtration

ZGF Spring Filter

Nidge

  • The “nidge” is a precision bump machined on the top surface of the coil creating the filtration gap.
  • Consistent & Reliable performance
  • The particles are kept on the outside of the coil.

Valley

  • The filtration gap is created by a “valley”.  This valley or impression cause particles to get trapped thereby reducing the effective filtration and increasing cleaning frequency
  • Filter elements foul and require removal of discs for manual cleaning
  • Depth allows particles to get inside, difficult to remove

ZGF Spring Filter 

Maintenance Free

  • The stainless-steel Spring Filter requires virtually zero maintenance

Frequent Maintenance

  • The discs must be removed monthly for manual cleaning

EZ Clean Tornado centrifugal separator

The EZ Clean Tornado is a patent pending centrifugal separator that puts a new spin on an established technology!

The Tornado separator is the future of centrifugal separation technology.  The innovative separator utilizes an internal blade design.  The blades create a unique and beneficial flow path through the separator that increases the “G – Force”, resulting in more effective and efficient particle removal.

If you are for looking economical particle removal, the Tornado separator is your new choice for centrifugal separators.  The Tornado is a simple but extremely innovative device.  The Tornado has no moving parts and no media.  Tornado effectively removes particles without any regular maintenance.

Tornado centrifugal separators are used in Power Generating plants, Automotive plants, Steel Mills, and even in the Oil & Gas fields. They are utilized to filter machining coolant, wash solutions, cooling / process water, quench fluid and many other process fluids. 

With sizes ranging from 2” to 20”, the Tornado can handle flows from 52 gpm to over 12,000 gpm.

To see the Tornado centrifugal separators basic principle of operation, click on the Tornado animation. The animation shows how the patented blade design results in increased particle velocity and higher applied “G-forces”.  As the fluid spins through the length of the separator, the particles are forced to the outer wall and then to the low velocity solids collection zone at the bottom of the separator.  The clean fluid is directed back up and into “clean zone slots” and out the top of the separator.
