Compressed Air Best Practices - September 2008 - (Page 15) Focus Industry FOOD PACKAGING & PROCESSING | 09/08 | This is occurring because the dryer and filtration system is undersized. The dryer and filters are sized for 500 cfm maximum air flow. This air compressor configuration is capable of delivering over 900 cfm. The in-line filters could and probably are contributing to the problem as well. They appear to have been sized for a much smaller system. The pressure drop across this section is extremely costly as for every two psig of differential pressure increase there is an increase of 1% in the electrical energy cost to overcome this differential. The Contaminant Removal System has a high pressure drop of 12–20 psig. The air dryer in use in the boiler room is currently out of service. It appears to be a very old deliquescent dryer. We recommend it be taken out of the system. DO NOT RELY ON MAKESHIFT SOLUTIONS trust in the system solutions from BAUER.
