We believe, after seventy-six years' experience in air handling, that some of this excessive maintenance cost comes from improper selections of equipment. -"Buffalo" manufactures 20 lines of fans and blow- Tbe "Q Ml era, for every service from residential kitchen ven tilation to sub-zero airplane instrument testing-- from 20 CBM to 600,000 CFM.
