SI/DI/DIT
The SI/DI/DIT series are belt driven single inlet, double inlet centrifugal forward curved fans, specially designed for handling relatively clean air in supply, exhaust and ducted return air applications. These line of ATC blowers are available in 7 sizes in single inlet (SI), 11 sizes in double inlet (DI) and 3 sizes in twin double inlet (DIT), ranging from 9” through 36” wheel diameters. These fans are manufactured under strict quality assurance standards to ensure high efficiency and quiet operation in a compact design which produce high air volumes at low speeds.
Construction features
- Housings, scrolls, inlet cones, rings, drive stands, and all structuralsupports are made of heavy gauge all welded steel construction.
- Forward curved galvanized steel wheels are statically and dynamicallybalanced at the factory and designed for optimum performance, longlife and quiet operation.
- Electrostatically applied powder coating is standard on all ATC fans. Forspecial requirements, please contact the factory.
- The fans are available in 3 different construction arrangements: SI(Single inlet), DI (Double inlet), DIT (Twin double inlet) ; field rotatableto four 90° standard discharges (TH, DB, BH, UB);
- 3 distint type ofmotor mounting positions: floor base mounted, structural basemounted, scroll mounted; clockwise (CW) or counter clockwise wheelrotation.
- Self-aligning heavy duty, pillow blocks ball bearings are designed tooperate under the most severe atmospheric conditions and aresupplied by the most prestigeous world wide manufacturers.
- Shafts are designed for long life in different diameters and lengths,turned, ground and polished of solid SAE 1045 steel for smoothoperation, key-wayed and protected with a corrosion resistant coating.
- Adjustable steel motor plate pivoted at one end for ease of belttensioning.
- The SI/DI/DIT series are the ideal for the general belt drive ventilationapplications, using the combination of high quality sheaves, v belts,high efficiency motors in order to handle a wide range of air volumesand pressures
Applications
