What should I set my compressed air at for my pulse-jet baghouse?
The manufacturers of the baghouse usually have designed the unit to operate with a specified pulse pressure. In the absence of manufacturers recommendations some general rules can be applied. For a typical baghouse with 10′-12′ long bags the pulse pressure should be between 80-100 psig. Bags of 6′-8′ would be lower (60-80 psig) and bags of 14′ or more may require 120 psig or more to clean adequately. As a rule of thumb, the lower you set the pressure the more energy savings you will see as long as the inlet draw of the baghouse is operating satisfactorily.
