Clear Edge Filtration CFE GmbH

For over 30 years, Clear Edge filtration has been manufacturing flat, pleated filter cartridges, called compact filter elements (CFE™). Clear Edge Filtration has provided products and services to a wide range of customers in the areas of mining, tunnel construction, laser cutting and liquid painting as well as application areas for dedusting.

FG-product-air-FiltermedienDEDUSTING FILTER MEDIA

Filtration Group Industrial offers a large selection of filter media for dust filter cartridges. This ensures that the right solution can be found for virtually any application.

Special surface materials with web coating, PTFE membrane or meltblown micro-fibers guarantee a cost-optimized and reliable continuous operation of dedusting systems.

For the pharmaceutical and food services industry, FDA-approved materials are available.

Pleat distance control

Star-pleated FGI dust filter cartridges are used to separate very fine particles from gases. The gas flows inward through the cartridge and is discharged via the open end cap on the top.
Due to the new FGI pleat distance control for polyester and cellulose based filter media, the performance of the Filtration Group Industrial polyester cartridges increase up to 44 %, compared with standard polyester cartridges on the market.



FGI-product-air-Filterelemente-konischStar-pleated FGI dust filter cartridges are used for separation of smallest particles from gases. The dust-laden gas passes through the vertically mounted filter cartridge from the outside to the inside and exits through the top open end cap. Optimization efforts regarding flow and strength have led to the conical element shape. The cleaning of the filter cartridges using the extra-quiet FGI multi-jet nozzle works much more effectively than with conventional nozzles. The improved cleaning behavior compared to cylindrical filter cartridges and the more favorable flow conditions result in up to 30 percent better performance of dedusting equipment.


FG-product-air-FG-product-air-Filterelemente-zylindrischStar-pleated FGI dust filter cartridges are used for separation of dust from air and gases in virtually all branches of industry. The consistently high quality of FGI dust filter cartridges is maintained through regular and comprehensive performance inspections of materials that go into production. Application tests are also conducted at our test benches in the development lab and in facilities on site. Products and production methods can then be improved or redeveloped on the basis of these results.


FG-product-air-KompaktfilterFor more than 30 years compact filter elements
(CFE) have been the first choice for dust collection systems in critical industrial processes.

Filtration Group has many years of experience in the development and application of compact filter elements (CFE). These are used in a wide variety of applications:

  • Laser cutting – 99.995% of dust is separated
  • Wet painting – in painting lines the strongly adhering paint overspray is continuously filtered
  • Mining and tunnel construction – requires very robust filter media
  • Metalworking – when working with metals, oily dusts often cause problems with conventional filter cartridges

Our CFEs are completely tip-bonded, self-supporting filter plates that combine the advantages
of filter bags and filter cartridges. Depending on the application, compact filter elements can be equipped with oil
and water repellent polyester fleece, microporous coatings or PTFE membrane.

Furthermore, CFEs can also be used in environments with high dust loads and can be efficiently cleaned by pulse jet

Our CFEs offer a number of valuable advantages:

  • up to 3 times more filter surface compared to conventional filter bags
  • very small filter size.
  • high efficiency up to 99,995%.
  • long service life
  • excellent cleanability due to the compressed air impulse

FG-product-air-AbreinigungseinheitenWith Filtration Group rotating wings and
multi-jet nozzles, optimized cleaning units are available for star-pleated filter cartridges. The special technical
details of these components are based on our years of practical experience and elaborate development trials.


In machining and forming processes in industry – for example in modern machine tools – cooling lubricants (oil or emulsions) are used under high pressure. This allows increased oil mist and emulsions to enter the ambient air. To ensure that the aerosol concentration does not exceed the MWC (maximum workspace concentration) limit values, the cooling lubricant mist must be reliably and continuously extracted and cleaned from the working area of the machines. This is a problem traditional systems are unable to handle.


Dedusting UnitsWe combine all our experience in our dedusting units. The interaction of FG filter elements, specially developed cleaning units and optimally designed housings results in our compact dedusting systems. Our standard range starts with small top on filters and extends to large central exhaust systems, if required also with ATEX version. If required, our standard units can also be flexibly adapted to customer requirements in order to achieve the optimum solution for continuous and trouble-free operation with low maintenance requirements.


Whether time- or differential pressure-triggered cleaning by our two cleaning control types or the use of a device for filter aid dosing, we offer you an extensive portfolio of spare parts and accessories around filter elements and dedusting units. In addition, we deliver threaded connections for mounting the filter elements on the filter plate on order.
