 Standard Filter Bags

Description:

Profilter is partner in France for Well known manufacturer. This company manufactures high quality liquid filter bags to fit standard size filter vessels, as well as custom designed products where requested. The constituent materials have been chosen for their purity, ensuring consistant high quality and performance. Filter bags are available in traditional stitched form or with a fully welded construction, and are fitted with a comprehensive choice of rings.

Features:

  • 7" or 4" Steel rings (Steel or Stainless Steel) which fit universally into all filter housings. Polypropylene rings and Stainless steel bands are also available
  • Custom designed moulded Welseal (Polypropylene or Polyester) welded rings, giving more positive sealing, needle hole elimination and grab handles for faster and easier bag installation and replacement. A Welseal ring product is fully combustible asnd also makes polymer recycling from used bags possible.
  • Custom designed positive sealing Santaseal moulded ring, for applications where high temperature or chemical resistance properties are required.

Fully Welded Filter Bags

Description:

Profilter is a supplier of fully welded filter bags, which are available for applications requiring standard polypropylene or polyester felts, extended life felts or high efficiency media.
All seams are welded rather than sewn, and combined with either of our positive sealing moulded Welseal (polypropylene or polyester) welded rings, no process liquid can bypass through needleholes caused by the sewing process or around a sewn snap ring. The Welseal ring forms a hermetic seal between the filter bag and housing, eliminating any possibility of bypass around a steel ring, which is a potential source of product contaminaion. These features ensure that fully welded filter bags perform to a higher efficiency than a sewn equivalent.

Features:

  • Ease of use
  • Total elimination of needleholes
  • Total elimination of possibility of thread contamination
  • Enhanced seam strength
  • Higher performance efficiencies
  • More positive seal between filter bag change and installation
  • Fully combustible
  • 100% synthetic components enable polymer recycling


Additional Information:

All filter bags are manufactured to ISO 9000 2000 quality standards and under silicone free conditions. Constituent polypropylene and polyester felts are manufactured using 100% virgin fibres, ensuring maximum purity and consistent performance.
 
 

Extended Life Filter Bags

Description:

Extended Life filter bags are available in polypropylene or polyester in micron ratings from 1-100, and have a lifetime of up to 4 times that of the equivalent standard filter bag. Increased thickness of the filter media compared to that of the equivalent standard filter bag enables an increased retention of particles, resulting in a prolonged filter bag lifetime.
The extended life filter media also has an asymmetric structure, which acts to increase the filter bag lifetime and enhance filtration efficiency. Progressively smaller particles are captured as the fluid follows a tortuous path through the graded density media, stopping the filter bag from blinding prematurely, whilst capturing a higher percentage of particles.

Features:

  • More efficient filtration process
  • Minimisation of equipment downtime
  • Minimisation of engineer exposure to process liquids
  • Fewer bags to change and dispose of compared with standard felt filter bags - more environmentally friendly
  • Excellent at removing deformable particles such as gels
  • Conforms to EC food contact directives


Additional Information:

As standard, the extended life filter bag is fully welded, maximising filtration efficiency by eliminating fluid bypass through needleholes or around a snap ring. The external surface is highly glazed, eliminating fibre migration into the filtrate.
 
 

High Efficiency Filter Bags

Description:

Profilter provide High Efficiency filter bags in all standard sizes, giving absolute rated depth filtration between 1 and 25 microns. Constructed from a composite of polypropylene microfibremedia, particle retention is achieved to efficiencies of upto 99,98%. The high density of small diameter fibres compared to that of a standard needlefelt enhances particle retention, leading to superior, highly efficient filtration.
Combined with our polypropylene Welseal ring, high efficiency filter bags are available with a fully welded construction, ensuring that no by-pass of process liquid can occur through needleholes, and eliminating any possible contaminations from sewing threads. each layer is individually welded, giving enhanced filter bag integrity and seam strength compared to single weld construction methods.
The Filter bag also features an outer membrane, which prevents fibre migration into the filtrate as well as providing added support to the filtration media.
The high efficiency filter bag is constructed from FDA listed materials conforming to code of Federal Regulations 21 CFR Part 177, governing requirements foir food contact applications. Major idustrial applications include pharmaceutical, food, beverage and potable water.
High Efficiency bags are now being used in applications previously dominated by expensive cartridge filtration, due to higher dirt holding capacities, longer service life and lower overall cost whilst maintaining the required filtration efficiency.
Applications include toiletries, cosmetics, fine and speciality chemicals, electronics, water treatment, protection of membranes in reverse osmosis systems and as a pre-filter to low micron cartridge systems.

 
 

Food and Pharmaceutical Grade Filter Bags

Description:

Bag Filters, when used in food, beverage or pharmaceutical applications, must conform to C directives governing plastics in contact with food. Migration limits of contaminants from polymers into a food product have been imposed, and independent testing and certification of component materials is required to ensure these regulations are satisfied. Stringent manufacturing and warehousing conditions as well as special packaging procedures are also required to eliminate other sources of contamination.
Profilter supply food and pharmaceutical grade filter bags which fully satisfy the above conditions. The constituent materials have been chosen for their purity, giving low levels of migration and ensuring consistant high quality and performance.

Features:

  • Polypropylene and Polyester needlefelt
  • Polypropylene and polyester extended life needlefelt
  • Nylon monofilament mesh
  • Polypropylene microfibre


Additional Information:

Combined with either of our positive sealing Welseal (polypropylene or polyester) welded rings, needlefelt food and pharmaceutical grade filter bags have a fully welded construction as standard. The external surface of the filter bag is glazed, eliminating any possibility of fibre migration into the filtrate. All filter bags are manufactured to ISO 9000 2000 quality standards. Further information on food and pharmaceutical grade products is available on request.
