The Infastaub filter series Infa-Micron is a complete series for dedusting of sophisticated processes where toxic dusts or powders, e.g. API (Active Pharmaceutical Ingredient), occur. Lowest residual dust contents up to 0.001 mg/m³ and reliable protection of staff during operating and maintenance are demanded for these applications. Cassette filters MKR and MKM as well as cartridge filter MPR are applied for these special demands.
Requirements for operating safety and protection against contamination plus consideration of health and environmental aspects while de-dusting require a special construction and manufacturing of these filter units. Risks during filtration of high active ingredients, harmful or toxic dusts and suspended matters are minimized with these units.
The range of the Infa-Micron filter series permits its use for a multitude of mostly dangerous manufacturing processes. The specific demands of the most different areas of application were considered at construction. The modular design of the filter series allows an optimum of flexibility. Extra equipment or individual components for special purposes or building conditions can be produced by request. Thus customised unique filters are available on the one hand and favorable series modules on the other hand.
Change of filter cartridges and filter cassettes can be performed on all Infa-Micron filter units without any tools. If requested, the inspection covers can be opened without screws or other laborious locking devices with only few moves. The filter cartridges and filter cassettes are tightly fixed with pneumatic (for MKR and MKM alternatively also mechanical) fastening devices in the filter unit.
Measures of constructive explosion protection ensure safety while operating the filter units. In case of an explosion in the raw gas area of the filter the extending flame front is held back in the filter elements of the 1st filter stage. The resulting explosion overpressure is relieved into the clean gas side above the 1st filter stage, so that explosion overpressures of only max. 1 bar g rise within the filter housing. Because of pressure shock resistant construction the explosion is kept isolated inside the filter. Explosion pressure relief or explosion suppression systems are not necessary.
This was proved by explosion tests for dusts of dust explosion class St2 as well as gases of groups II A and II B and for hybrid mixtures.
The main fields of application of Infa-Micron filter units:
- Production of potential dangerous or valuable products
- Dust-raising processes as e.g. mills, tablet presses, granulators, coaters, mixers and packaging machines
- Potentially explosive dusts, gases and hybrid mixtures
- Processes with highest demands on residual dust content, functionality, safety for operating and maintenance as well as availability
- Branches chemistry, pharmacy, metal / heavy metal, disposal, hazardous waste, recycling, nuclear technology etc.
