The Drum Filter effects for RDF : Let's see the drum filter effects for QLOZONE RDF.We conducted a test with the PM-05 Rotary Drum Filter, using red 80 micron fine sand to pass through the filter, our PM-05 has a 75 micron pore size. The conclusion was that 95 per cent of the fine sand would be intercepted by the filter, leaving some very fine sand to be ignored by the filter. This test also had another purpose, we upgraded the sealing performance of the sealing ring. The test verified that this was a very successful upgrade.
