| Drive System | Available in direct drive or belt drive configuration depending on airflow and pressure requirements. | Cast pulleys and V-belt, dynamically aligned. |
| Base Frame / Mounting Plate | Ensures vibration-free operation and stable mounting on roof curb. | Heavy-gauge steel, hot-dip galvanized. |
| Top Cover (Cowl) | Aerodynamic weatherproof cover designed to protect against rain and dust while ensuring free discharge. | Galvanized steel or aluminum, powder coated. |
| Bird Screen / Mesh Guard | Prevents entry of birds, leaves, and large particles. | Galvanized or stainless steel wire mesh. |
| Bearings | Sealed-for-life ball bearings for smooth and quiet operation. | Heavy-duty, maintenance-free bearings. |
🏗️ 2. FAN STRUCTURE
-
Horizontal Discharge Design:
Air is discharged horizontally through a side outlet, suitable for installations where vertical discharge is not desired (e.g., near neighboring buildings or air intakes). -
Centrifugal Flow Path:
The fan draws air vertically from the duct below and discharges it horizontally through the outlet chamber, providing efficient system airflow. -
Weatherproof Construction:
Includes a protective cowl, base plate, and drain holes to prevent rainwater accumulation. -
Modular Design:
Allows easy access to the motor and impeller for cleaning or maintenance by removing the top cover. -
Vibration Isolation:
Equipped with anti-vibration mounts or rubber grommets to minimize noise and mechanical stress.
