I HAVE BEEN INVOLVED WITH INDUSTRIAL CLOTHS DRYERS FOR MANY YEARS AND HAVE BEEN SEEKING INFORMATION OF THE DRYER AIR FLOW AND WHY SOME MANUFACTURERS USE A LOW VOLUME CFM (5-6000) AND OTHERS USE A HIGH AIR CFM (9-11000 ) CFM. I HAVE COME TO BELIEVE THAT THERE IS A REASON FOR THE HIGHER AIRFLOWS, AND THAT IT IS ONLY BENIFICIAL FOR A SHORT PERIOD OF TIME AND AFTER THAT IT BECOMES A DETRIMENT IN THAT IT PULLS HEAT FROM THE DRYER BEFORE IT HAS HAD A CHANCE TO DO IT JOB, THEREBY ADDING TO THE FUEL COSTS. ANYONE HAVE ANY INFORMATION?
