Industrial Models - CFA/CFC

  1. What are the differences between a CFA and CFC series air curtain?

    The motor horsepower and the size of the blower wheels and housings.

  2. What gauge steel is used on the top cover and the gauge of steel used on the lower air blower assembly for all CFA/CFC series air curtains?

    The top cover is constructed of 16 gauge steel and the lower air blower section is constructed of 14 gauge steel.

  3. Why does top air inlet deliver more air than a front air inlet on all CFA, CFC, CFX, CFY, DGA, DGG series air curtains?

    The top air inlet delivers more air as the opening is larger than a front air intake.

  4. How are multiple blower shafts connected on models: CFA, CFC, CFX, CFY, DGA, DGC & EWD?

    Sleeve and flexible couplings. This design is to increase the stability of the shaft and prevent sagging throughout the unit.

  5. What is the diameter of the blower shaft for models CFA & CFC air curtains?

    One (1) inch shafts are used on all CFA/CFC models.

  6. What is the maximum number of blower wheels/housings installed on any single shaft for models: CFA, CFC, CFX, CFY, DGA, DGC & EWD?

    Two (2) blower wheels and housings per single shaft. Two blower wheels and housings are for maintenance purposes. Total of five (5) blower wheels and housings for CFA models and six (6) for CFC models.

  7. What is the advantage of Berner's design for the attachment of the motor to the shaft on all CFA & CFC series air curtains?

    A sleeve and coupling are installed on each side of the motor. The sleeve and coupling will reduce the load on the motor to increase the motor life and make it easier to remove the motor for maintenance purposes.
