B.	Fans selected shall be capable of accommodating static pressure and flow variations of +/-15% of scheduled values.
C.	Each fan shall be belt drive in AMCA arrangements 4 [8] according to drawings. 
D.	Fans are to be equipped with lifting lugs.
E.	After fabrication, all carbon steel components shall be cleaned and chemically treated by a phosphatizing process to insure proper removal of grease, oil, scale, etc. Fan shall then be coated with a minimum of 2-4 mils of Permatector (Polyester Urethane), electrostatically applied and baked. Finish color shall be gray, RAL-7023. Coating must exceed 1,000-hour salt spray under ASTM B117 test method.
