A method is disclosed for recycling industrial air. Air contaminated by particluates is removed from the area of machnery, transported to dust collectors, and filtered. A small protion of the filtered air is discharged to the outside atmosphere while a substantial portion is recycled to the area of the machinery. Significant savings of energy are realized while less particulates are exhausted with the air into the atmosphere as contaminants.
