Trial your filter clean for free

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.
