The Cassette filter MICRON is a complete series for filtration of dusts and suspended matters that are respirable, hazardous to health or toxic. The MICRON-cassette filter Type MKR (pneumatical cleaning) count to it.

Thanks to the modular system the MICRON is available with one or two filter stages as cleanable housing filter or as not cleanable housing filter with subsequent safety filter. There is also a model available for mobile use at different dust sources or in laboratories. For the first stage, filter cartridges of the classes H10 through H13 are used as filter media, and the classes H13 through U15 for the second stage.

A special feature is the optional "Safe-Change" system helping maintenance personnel to carry out dust disposal and exchange of filter media free of contamination, that is without coming into contact with the dust.

As a result, there are main fields of application for the MICRON cassette filter for dedusting tasks in sectors such as chemical industry, pharmaceutical industry, medicine, heavy metal processing (e.g. accumulators, Hg fluorescent recycling), dyes, nuclear technology, decontamination etc.

Standard Design :

• Cleanable cassette filter in modular design with one or two filter stages.
• Change of filter cassettes on the clean gas side.
• Closed filter housing made of mild steel S235JR with hopper and dust discharge system respectively dust collection equipment.
• Pneumatic cleaning device with movable nozzle arm (backflush system) for cassettes of the 1st filter stage. Cassettes of the 2nd filter stage are not cleanable and will be changed after reaching the maximum pressure drop.
• Modular system for flexible adaptions to individual requirements, suitable up to +80 ºC.
• Electronic, programmed control unit for filter cleaning triggered by time cycle or differential pressure incl. control of nozzle arm and shut-off valve.
• Surveillance of single operating conditions by proximity switches and indication by plain-text display.
• Use of particulate filter cassettes of filter class H13 and higher (HEPA), tested according to DIN EN 1822.
• Filter cassettes in compact design with MDF-frame allow easy handling and thermal waste treatment (hazardous-waste incineration).
• Leak-proof test device for every filter cassette.
• Minimum shutdown time as well as low operating and maintenance costs because of high reliability and easy handling.

Pneumatic Cleaning

Options :

• 2nd filter stage (not cleanable) as safety filter respectively "back up filter".
• "Safe-Change" system for change of dust collecting bin and filter cassettes free of contamination.
• Dust discharge by lid bag, glove-box or endless bag system.
• Dust discharge by pneumatic conveying into central barrel with "Safe-Change" system.
• Adaptability for customized dust collecting barrel.
• Explosion protected design according to directive 94/9/EG (ATEX).
• Pressure-shock resistant design for reduced explosion pressure up to 1.0 bar g without additional, expensive relieve device for dusts of explosion class St2 gases up to group IIB and hybrid mixtures.
• Separated single chamber isolation e.g. for operating with hybrid mixtures.
• Gas tight by welded and strengthened filter housing for pressures up to +/- 250 mbar g.
• All housing parts, internal parts or components in contact with the product made of stainless steel.
• Filter cassette frame made of mild steel or stainless steel.
• Filter cassettes in different qualities and grades up to U15 according to DIN EN 1822.
• Filter control as PLC with any special function and interface to master process control system.
• Design for hot gases up to 180 °C.
• Electric heating of filter housing including thermal insulation.
• Control system and motors for special voltages.
• Connections for DOP / DEHS tests of 1st and 2nd filter stage.
• Design „Through the wall“ for fitting into cleanroom walls.
