Microfilter - electrostatically charged micro filter
 
Microstat filter achieve an excellent filtration efficiency and permit at the same time a good air permeability. The electrostatic effectiveness of microstat filter media will be obtained by a mixture of different synthetic fibres (modacrylic fibres, polypropylene fibres etc.). The progressive composition of the filter media enables the depth effect of the filter and thus a long lifetime of the filter.

 

  • Depending on grammage (30 – 400 g/m²) classes of coarse and fine dust filters between G2 and F5 will be achieved
    •                                              
  • Microstat filters are available in rolls or cut to the requested size, also packed in polybags if required
    •  
    Treatment capacities for our microstat nonwovens include:

    • converting or printing of washable qualities with edges sealed by ultrasonic
                                                

    • bonding in plastic frames
    • combination with PU foams
                                                

    • combination with grids for stabilization, e. g. with pleated filters
    • combination with activated carbon media
                                                

    • Together with you we will develop the most suitable filter quality for your vacuum cleaner
                                                
       
    Quality control
    In our own laboratory we test filter media concerning their filtration efficiency and air permeability at different flow rates. A particle counter determines the degree of separation for several measuring ranges between 0,3 and 10 µ.
     

    Possible application areas for microstat filters are:

    • coarse dust filters for air conditioners
    • fine dust filters for air cleaners and ventilation systems
    • motor protection or exhaust air filters for vacuum cleaners
    • vehicle interior filters
    • dust masks
    • medical-technical filters
