With the FilTEq RTF 11057 filter test rig Palas®
provides a reliable and economical test system for testing, development and quality control of cleanable filter media.
The filter test stands of the RTF 11057 series are characterized by the highest reproducibility of the test results.
With the RTF 11057 test rigs both standard filter media tests according to all common guidelines (VDI/DIN 3926 (1994 and 2004), ISO 11057:2011, ASTM D6830-02) including ageing can be carried out as well as under customer-specific conditions, depending on the operator's requirements.
This allows individual, realistic tests to be carried out as specified by various process conditions, e.g. in waste incineration plants, in the cement and steel industries, in the wood processing industry, the pharmaceutical industry, the chemical industry and others. These filter media tests can be carried out with different powders from practice, which allows a good correlation of the results to operating conditions. Different media can be optimized or selected for different applications with regard to their structure and surface treatment. Palas®
filter test rigs are already used in the international industry with great success.

The following characteristic data are determined in the test results for the comparative assessment of filter media in a standard test:
- The pressure loss of the unfiltered filter medium and the development of the residual pressure loss
- the evolution of the duration of a filtration cycle, i.e. the time between differential pressure controlled cleanings,
- the weight increase of the filter sample
- the development of the clean gas dust concentration over the entire course of the experiment
- the characteristics of the pressure loss curve and the structure of the dust layer remaining on the filter surface
- for particle measurement in clean gas, in addition to gravimetric measurement, the Promo Aerosol Spectrometer is preferably used
