HERDING®-sinter plate filter for surface filtration grant clean gas values of < 1 mg/m³, even with dusts of D50 < 1µm. The matrix consists of sintered polyethylene PE. An additional PTFE-coating gets into the pores of the PE-basic body and forms a micro-porous, non-sticking. This combined material is most extensively chemical resistant. The HERDING®-sinter plate filters are extremely stable in structure, rigid, water resistant and only need low-maintenance. The average useful life of a Herding ® filter can even exceed 10 years.
HERDING® sinter plate filters show a very high efficiency of separation and environmental compatibility. The filters can be recycled without any problems, no toxic waste has to be disposed off.
By using these filter elements in HERDING® HSL-units there is an optimum combination of positive attributes like: compactness, optimum flow behavior, ideal dust emission and an extensive operational safety, resulting from the rigidity of the matrix and of no wear and tear against abrasive media. At regular intervals or at pre-determined differential pressure the filter elements are cleaned on-line by a jet-pulse.
The filter elements are fixed only by a single screw – which makes maintenance easy and saves times. On request antistatic or even special design, e.g. for using cooling lubricants or aerosoles are possible. HERDING®-DELTA-filter are future-oriented; already today they meet what tomorrow’s environment and legislation will require. So in fact the separation efficiency shows a much better value than required by the BIA-certificate, regarding dust classification M.

Cages / Retainers
Pulse-jet style baghouses are designed to utilize fabric filter bags with internal support structures commonly referred to as cages. Cages provide a means of holding the filter bag open during the particulate collection cycle. Cages must be strong to withstand the pressure from the filter bag exerted during the particulate collection cycle.
Additionally, cages must be selected with the proper structure design to conform to the fabric requirements. Gas stream chemistry will determine whether special metals or special coatings will be required to reduce or eliminate corrosion to the cages' metal surfaces. Cage sizes, both length and diameter, can be crucial to the success or failure of the filter bag.
The strongest filter bag cage for pulse-jet baghouses is known as the "rigid wire" cage. It is designed to provide uniform support to the overall length of the fabric filter, utilizing "stringer" wires that are equally spaced around the circumference of the cage. Each stringer wire is then welded to support rings that are spaced along the length of the cage. The diameter of these rings plus the wire gauge of the stringers determines the overall diameter of the cage. Special cage tops, such as roll band and roll flange styles, are also welded to the stringer wires; thereby developing a strong internal assembly from which to attach the cage and filter bag to the baghouse tubesheet. The cage bottom is either interlocked to a stringer ring or welded to the stringers. Either method is equally sufficient for support.

Micro Air® dust collectors are engineered from the ground up with innovative design, and features that provide what counts most in a dust collector: functionality. From fine dust to coarse particulate, we can help make your plant a cleaner and a more friendly work environment.
Micro Air® dust collectors utilize cartridge filtration and are available in a large range of configurations up to 24 cartridge models. All are sized and rated for the proper air-to-cloth ratio to solve a wide variety of applications such as weld smoke, powder dust, grinding dust, paper dust, etc.
Key to our models is a revolutionary new cleaning system called Roto-PulseT. This is an on line system that continually cleansthe filters with a revolving, compressed air driven, tube. As air enters the tube, the force of the pulse causes the tube to rotate. While spinning, air exits the pre-drilled holes in the tube. The result is that air hits the entire inside of the cartridge, pulsing dirt particles away from the filter for a much more efficient cleaning cycle.

In a dust removal system, the filter cartridges are essential to ensure the efficiency of the entire system. They therefore need to have special features such as: A high filtering capacity to ensure maximum separation potential and in order to comply with even the most stringent standards, where required. A high degree of permeability, which translates into reduced pressure drops and therefore high energy saving potential. Clogging occurs infrequently, thereby guaranteeing a long working life and reduced operating costs.

U.S. Air Filtration can provide dust collector filters for all types of air filtration systems. A pleated bag filter is a bag made of a length of filter media folded into numerous pleats and shaped like a cylinder. The pleats are made such that the outer diameter of the pleated bag matches the outer diameter of a regular cylinder filter bag. The filter media is fitted to the bottom end cap and top sleeve arrangement and the bag cap is attached. The spacing of pleats is normally kept at 2-3 times the area of cylindrical bags which gives it that much extra filter media for the same space consumed.

Extraction and filtration units for dust:
The arising of hazardous materials in the form of coarse dust,fine dust and floating particles is often unavoidable in working processes. Extraction and filter units clean the air directly at the workplace. Thus, hazardous effects on employees as well as machines can safely be prevented. The optional recirculation ventilation results in the cut of energy costs. The application-oriented solution result from long-time experiences.
The filter cartridge units of ULT AG are equipped with automatic cleanable filter cartridges. The stationary extraction facility is used for a single-place and central extraction, according to the size. The large filter surfaces enable maximum filter stand life.
