Filter bags

Filter Bags – Extended life (POEX/PEEX)

The Extended Life filter bags (POEX and PEEX) provide outstanding performance on many types of contaminants such as gels, particles with wide ranges of sizes, and particles with various irregular shapes.

The coarse, pre-filtering layer is designed to provide long service life, capturing a large amount of contaminants without excess surface loading.

The POEX has been field-proven to hold up to twice the amount of contaminants as a standard felt filter bag, reducing waste volume and bag changes. The Extended Life filter bag is ideal for automotive coatings, chemicals, resins, edible oils and other fluid applications.

  • Excellent filtration on many contaminants – gels, particles with wide range of sizes and particles with irregular shapes
  • A coarse inner layer, graded pore structure, greater depth than standard filter bags provide excellent filtration performance
  • Available in polyester (PEEX) and polypropylene (POEX)
  • Twice the standard dirt-holding capacity of traditional felt filter bags to provide longer service life, fewer change-outs and reduced waste
  • Polypropylene bags are FDA compliant
  • Micron rating for polypropylene 5-100; polyester 1-100
  • PolyWeld® seam construction with hermetically sealing Polyloc® ring eliminates liquid bypass
  • Glazed finish eliminates unwanted fiber migration

Cotton on Tinned Steel String Wound Filter Cartridge

Flowrite Wound filter Cartridges are an improved, conventionally wound filter cartridge manufactured on state-of-the-art precision winding machines. Continuous length winding eliminates dead spots and bypass. The single strand, purpose-spun roving employs a strictly controlled material to produce a consistently high quality filter cartridge giving optimum flow and filtration performance.

Advanced manufacturing technology and strict in-house quality control, combined with a variety of wind patterns, ensures filtration that best fits the application to provide economical and consistent results time after time. For advice on specific applications contact Germ Africa

Features

  • Tinned Steel core and Cotton yarn materials
  • Four different cartridge lengths
  • Six different micron ratings
  • State-of-the-art winding machines

Benefits

  • Wide chemical compatibility
  • Fits most housings without joining
  • Suitable rating for most applications
  • Consistent reliable quality

Performance

The table below gives the water flow rate in l/min per single 10” cartridge, based on a pressure drop of 7 kPa. Higher flow rates will result in higher pressure drops, but in no case should the flow rate exceed 38 l/min/cartridge

Doulton

In 19th Century England, the River Thames was London s main water supply and sewer. Henry Doulton discovered that filtering water through a porous ceramic could stop people becoming sick from cholera and other water-borne diseases. This was a revolution in water treatment.

Fast forward 175 years and the ceramic filtration technology has advanced a long way, but the principles of our ceramic filters remain the same – providing safe, healthy, great-tasting drinking water wherever and whenever you need it. From a mud hut in Uganda to an office block in Utah, Doulton filters are working round-the-clock to provide millions of people with water they can enjoy and trust.

Doulton Stainless Steel – Counter top filter housing

Doulton® filters offer you bottled water quality on tap 24 hours a day. Our unique ceramic filtration technology produces drinking water of unrivalled quality. All of our filter grades have been microbiologically tested. Most grades also remove chlorine and improve the taste and odour of the water, while others use lead absorbtive media to take out toxic lead specifically and other heavy metals.

High Flow Series Filter Cartridges

Large Geometry Pleated Filters for High Flow

Graver High Flow Series filters feature a larger geometry to handle higher flows with fewer filter elements. The result is much faster, easier filter changeouts. In addition, the inside to outside flow allows for excellent dirt holding capacity, extending the time between filter changeouts.

Filter housings are also available and because of the filters high flow and dirt holding capacity, smaller systems are possible, reducing upfront capital costs.

High Flow Series Features – Benefits

  • 6” diameter, large geometry for high flows
  • Absolute retention ratings from 1 to 100 microns
  • Capable of flow rates up to 500 GPM in a single 60” element
  • FDA listed materials of construction
  • Inside-out flow retains contaminant even during change-out
  • Multi layer pleated construction with optimized surface area
  • Outer cage prevents media extrusion problem experienced with some competitive offerings
  • Unique Quad Seal gasket provides maximum seal integrity
  • Retrofits competitive high flow filter housings
  • Thermally bonded construction
