ARS 280T ROOF FANS (C-2320)

🔹 General Description

The Horizontal Outlet Roof Fan (Backward Curved Type) is a centrifugal roof-mounted ventilation unit designed for horizontal air discharge.
It provides high efficiency, low noise, and durable weatherproof construction, making it ideal for roof-mounted installations in commercial, industrial, and residential ventilation systems.

Equipped with aerodynamically optimized backward-curved impellers, these fans deliver high airflow with low energy consumption, ensuring long-lasting and reliable operation even under demanding environmental conditions.

🧩 1. FAN COMPONENTS AND MATERIAL PROPERTIES

🏗️ 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.

💡 3. MAIN BENEFITS

• High aerodynamic efficiency with backward-curved impellers.

• Low energy consumption and low noise operation.

• Weatherproof and corrosion-resistant construction suitable for outdoor mounting.

• Compact, space-saving design ideal for roof installation.

• Long service life and minimal maintenance requirements.

• Flexible drive options (direct or belt drive) to meet airflow needs.

• Easy access for inspection and servicing.

• Suitable for continuous 24/7 operation under various environmental conditions.

⚙️ 4. SPEED CONTROL

• Variable Frequency Drive (VFD):
  Allows smooth adjustment of motor speed and airflow for energy savings and system optimization.

• Multi-Speed Motor Options:
  Fans can be supplied with two or three-speed motors to match airflow demand.

• Belt Tension Adjustment:
  For belt-driven models, speed can be adjusted by varying pulley diameters.

• Direct Drive Models:
  Offer precise and maintenance-free speed control via electronic controllers.
