How clean does the filter cleaning machine clean the filters?
The GFCM machine has been tested by the Southwest Research Institute to identify the cleaning capabilities of the machine. The study found that after 4 cleans the machine had actually increased in filter efficiency whilst only having an 8.6% increase in restriction. The cleaning results are dependent on the type of filter and the operating environment, however we recommend 4-6 cleans per filter. A study was completed by a southwest research institute where a filter was loaded with dust, cleaned by the GFCM then measured. This cycle was completed four times with the following results.
