Filter bag test

Filter BAG test

The availability of a plant mainly depends on the satisfying condition of the installed flat-bags with regard to

the gas flow rate to ensure the complete gas and particle collection at the extraction point and
the residual particle content in the clean gas for the observance of the requested emission limit values in continuous operation.

Therefore, it is of particular importance for each plant operator to be aware of the actual condition and particularly of the remaining service time of the used filter bags. In this respect we are offering you examinations of the flat-bags installed in your filtration plant in our flat-bag testing laboratory.

Our advantage for you:
New equipment for filters delivered and mounted by LUEHR FILTER will of course be supplied with an adequate new service life warranty.

THE EXAMINATIONS BELOW ARE REALISED AS A MATTER OF ROUTINE

VISUAL INSPECTION OF
SUPPLIED FLAT-BAGS

DETERMINATION OF GEOMETRIC DATA

WEIGHING PARTICLE CONTENT

CONTROL OF EFFICIENCY OF FILTER REGENERATION MEASURES REGARDING THE AIR-TO-CLOTH RATIO

CONDITION UPON DELIVERY

CLEANING SIMULATED AS IN PROCESS FILTRATION PLANT

SPECIAL COMPRESSED AIR CLEANING

MANUAL CLEANING WITH LANCES

MICROSCOPIC EXAMINATION OF THE FILTER FABRIC
AND OF FILTER DUST INCL. MICROSCOPIC
SINGLE GRAIN MEASUREMENT

IN CASE OF NEED EXAMINATION OF DUST LAYER AND IF NECESSARY, OF FILTER FABRIC CONCERNING RELEVANT PARAMETERS, TYPICALLY E.G. pH VALUE, ALKALINITY, PETROLEUM ETHER EXTRACT.

RESIDUAL BREAKING STRENGTH BY MEANS OF FORCE-EXPANSION DIAGRAM

The test results obtained are sent to you in a comprehensive report. Of course, we will also give you information on the expected remaining service life in the report and, if necessary, make suggestions for optimising operation. If it is advisable to refit the filter system, we will submit an offer for replacement bags, taking into account the test results and our extensive practical experience gained over many years.
