Industrial Air

Our filter systems clarify the question of pure air

For air pollution control, Filtration Group offers filter systems, components and accessories that meet the highest standards of dedusting technology. The experience gained over decades of development can also be seen in the design, choice of materials and construction of filter cartridges, which can be optimally integrated into the respective production stages. The solutions, which reliably and thoroughly remove dust from air and other gases, contribute to a longer service life of machines in industrial production, as well as to a healthier work environment and a cleaner environment. A sensible investment that is anything but a shot in the dark.

Clear Edge Filtration CFE GmbH

For over 30 years, Clear Edge filtration has been manufacturing flat, pleated filter cartridges, called compact filter elements (CFE™), as well as ceramic filter elements (Cerafil™). With its head office in Salzgitter, Germany, 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.

Logo of Filtrair

Filtrair B.V.

For over 50 years, Filtrair has been a leading manufacturer of synthetic filter media and rigid pocket filters. The filter media for intake air provides ultimate protection against the intrusion of harmful, natural or organic dusts and pollutants for indoor areas as well as for commercial, industrial and gasturbine processes. We are a market leader for filtration in automotive body repair facilities.

Filter Media

DEDUSTING FILTER MEDIA
FILTRAIR FILTER MEDIA

Filtrair's fine and coarse filter media are 100% synthetic. The high performance fibres consist of a multi-layer technology with progressive density and have a very high dust absorption with optimal pressure drop behaviour. Filtrair has a unique hydrophobic media line that has been specially developed as a low-pressure pre-filter for pleated static cartridge fine filters of combustion engines and air intake systems. This media line offers a number of valuable benefits:

  • Significantly longer life of static cartridges
  • Easy and fast installation and replacement
  • Coalescing function in high humidity conditions

Pocket Filters (Filtrair)

Filtrair pocket filters consist of progressive, multi-layer and synthetic air filter media. The pocket filters are fully rigid and impregnated. Diamond spacers are fitted in the pockets to ensure optimised aerodynamic flow behaviour. An aluminium ring in the frame ensures optimum stability. Filtrair pocket filters are welded and framed in PU injection moulding machines. They are mainly used in a prefilter stage.
The pocket filters are used in the following markets:

  • Air intake for gas turbines, compressors and engines,
  • Wind Turbines
  • Automotive Paint booths / painting plants,
  • Industrial processes (food/pharmaceutical)
  • Ventilation systems for e.g. public buildings, schools, offices, computer rooms, etc.

Conical Filter Elements

Star-pleated Filtration Group 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 Filtration Group 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.

Cylindrical Filter Elements

Star-pleated Filtration Group dust filter cartridges are used for separation of dust from air and gases in virtually all branches of industry. The consistently high quality of Filtration Group 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.

Compact Filter Elements (CFE)

For more than 30 years, Clear Edge has been a leader in supplying cost-competitive dedusting systems for critical industrial processes.

We have many years of experience in developing and using compact filter elements (CFEs) that are used in a full range of applications:

  • Welding fume, especially in laser cutting in high-purity environments
  • Automotive, including paint spraying
  • Construction and mining, including tunnel construction
  • Milling, especially power transfer

Our CFEs are highly developed, self-supporting filter units with proprietary technology that combines the advantages of filter bags and cartridges. Depending on application, Clear Edge can provide the filter elements with oil and hydrophobic, temperature resistant, microporous coatings, PTFE membrane surfaces and antistatic finishes.

In addition, CFEs can also be used in high-dust environments and can be efficiently cleaned by back pulse cleaning.

Our CFEs offer a number of valuable advantages:

  • up to three times more filtration area compared to conventional pocket filters
  • can reduce the volume of the filter housing by up to 70 percent.
  • can save up to 40 percent of operating and energy costs.
  • high level of effectiveness
  • long service life (3-5 years)
  • excellent cake removal using pulse cleaning
  • simple and fast to clean, to install and to replace
  • can be added to existing systems
  • CFEs are more compact and thus allow installation indoors.

Oil Mist Separator LGA and ASL

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 units

We 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.
