"bonflow" Resin Bonded Media

What is Vats "bonflow"?

Vats "bonflow" is a rigid, graded-density filter cartridge constructed primarily of cellulose fibers, and a tough, chemically resistant thermosetting melamine resin. The proprietary manufacturing process results in more fibers towards the center core region, creating a graded-density structure. The thermosetting resin "bonds" the fibers by cross-linking the resin and cellulose resulting into a permanent rigid matrix.  Vats "bonflow" cartridges are grooved to significantly increase the surface area and extend the service life. Vats "bonflow" is manufactured and tested to deliver quality, consistency, and absolute cost effective filtration performance. Vats in-process quality assurance provides the control that results in consistent cartridges with defined ratings time-after-time.

Vats "bonflow" --The Clear Solution

Vats continues a 15 year tradition of innovative & cost effective solutions to challenging industrial filtration applications with Vats "bonflow".  Vats "bonflow" is truly graded density, high efficiency, nominal rated, rigid (non-compressible) resin bonded filter cartridge.

Consistent quality and performance with high efficiency cartridges from 0.2 to 50 microns make Vats "bonflow" the clear choice in the confusing world of indistinguishable "me too" cartridge filters.

Consistent Performance

Rigid structure Vats "bonflow" provides consistent performance.  Unlike many competitors, Vats "bonflow" does not unload or lose filtration efficiency throughout its usable life.  Rigid, graded density & grooved structure, provides a significant life advantage over the competition.
Vats provides quality solutions throughout India for the most challenging filtration applications. Vats filtration systems include clarifying filters, pre-filters, final filters, stainless steel housings and engineered skid-mounted systems designed and sized for specific applications.
Vats "bonflow" filters are food grade filter elements confirms to FDA specification.
View the toxicity certification which confirms that the liquid filtered through Vats "bonflow" does not get contaminated and can be of injectible quality.

"bonflow" v/s PP

The true comparison for the filter elements should be based on -

  • Quality – NTU, SDI, etc.
  • Throughput at what quality level.
  • Consistency within same elements and for consecutive replacement.
  • Disposal hassles.
  • Inventory - Higher chemical compatability leads to reduced inventory.
  • Any other.

For general-purpose application and critical application PP spun or PP wound filter elements are used.

Listed below are some comparison points

1. Particle Unloading:

Initially as per the morphology of cartridge, it holds the particles.As it starts developing some pressure drop it changes its morphology. Change in porous structure (morphology) is the result of elastic nature of PP material. It expands its porous structure after getting pressure, resulting into release of already hold particles. Generally known as particle unloading. Whereas "bonflow" material is Rigid in construction

Particle Unloading
All the above leads to inconsistent filtrate quality within the service life of cartridge. Please see the following graph
following graph

2. High Dirt Holding Capacity:

In case of "bonflow" material, the construction of cartridge is Graded density type whereas in PP the construction is True density type. So the dirtholding capacity of "bonflow" cartridge Filter is 4-6 times greater than that of PP True Density

True Density Cartridge - e.g PP spun/ wound
Graded Density Cartridge - e.g. "bonflow"

3. Incinerable:

For various atomic industries disposal of solid is very critical and essential issue. Vats "bonflow" cartridges are made of cellulose so it is very easy to dispose by incineration, it does not create any harmful gaseous product like in case of PP

To overcome all these disadvantages Vats is offering "bonflow" filter elements so as to get consistent quality and higher dirt holding capacity at the same quality throughout the service life of cartridge, see the above graph for "bonflow"’s consistent performance.
