Complete Filters​

Reliable, According To Standard, Adaptable

To reliably determine the quality and efficiency of filter elements, it is important to test energy consumption (pressure drop), loading and particle separation efficiency in addition to total penetration.

Precise measurement requires adjustment of the measuring channel to the size of the filter element in terms of flow control and aerosol distribution

Palas® has more than 35 years of experience in the field of filter testing and is continuously developing test stands of the highest quality to meet a wide range of requirements.

Testing Of All Kind Of Filter Elements

Palas® has filter test stands for all possible applications and filter elements.

For example, the new FET system can perform defined tests on filter elements in minimum size 100 x 100 mm, medium size 300 x 300 mm and larger (610 x 610 mm). If required, Palas® can also manufacture filter test stands to your specifications – also for even larger filter elements. Just let us know what your requirements are.

The measurement results of the test bench are better than the standard requirements:

  • ISO 24693-5 HEPA/ULPA filter element
  • Room air filter according to ISO 16890
  • ISO 11155-1/3 Motor vehicle cab air filter
  • DIN 71460 Automotive Interior Filters

Thanks to individual adapters and customer-specific adjustments to the airflow, the devices can be used with various filter elements.

The New FET System

  • Accurate, versatile testing
    • Measurement according to ISO 29463-5 and 29463-3, as well as ISO 16890 (ISO ePM1; ISO ePM2.5) in one channel possible
    • Particularly wide range of application for separation efficiency measurement from 20 nm to 40 µm
    • Measurement of dust holding capacity possible
  • Flexibility and ease of use
    • Customization of filter adapters, flow channel and measuring ranges possible for optimal test performance
    • Modular compact design for small filter elements, low space requirement
      o Horizontal design for minimization of particle losses
    • Calibration of raw gas/pure gas not necessary, because only one sampling and one measuring device is used
  • Safety
    • Logged results based on relevant standards
    • Factory tested and calibrated test stands
