However, you're better off operating the augur all the time. Otherwise, so much dust may accumulate that when you start up the augur, the heavy load will damage the augur shaft. A dust collector has a system to clean its filters with pulses of high-pressure air. The manufacturer sets the pressure and the time interval of the air pulses, which may be once every two or three minutes. Don't tinker with the factory settings, said John Cignatta.
Some contractors think they keep their filters cleaner by speeding up the pulses of air.
This just wears out the filters faster. Furthermore, said Cignatta, filters can be too clean for their own good. After all, a filter needs a cake of large lead-dust particles to capture the smaller ones. Similarly, contractors can get carried away turning up the air pressure on the filter-cleaning system of an ECS machine, said Tom Euart. If it's too high, the cleaning system could go bonkers and shut down.
