Key Features & Benefits
-
Automatic Louver Mechanism: The shutters are designed to open automatically via the airflow when the fan starts and close tightly via gravity when the motor stops. This prevents backdrafts and maintains the internal climate of the facility.
-
High-Volume Air Exchange: The 1.1 kW$motor is optimized for moving large volumes of air at low static pressure, making it ideal for general area cooling and air freshening.
-
Rugged Construction: The heavy-duty galvanized frame is built to withstand the South African climate, resisting rust and structural warping even in high-humidity environments like greenhouses.
-
Low Maintenance Direct Drive: By eliminating belts and pulleys, this fan offers a more compact design with fewer wearing parts, leading to reduced downtime and lower long-term service costs.
-
Safety First: Includes a heavy-duty rear wire guard to prevent accidental contact with the blades from the interior side.
Primary Applications
-
Industrial Warehouses: Removing stagnant heat and odors to improve worker comfort and safety.
-
Agriculture & Livestock: Critical for ventilation in poultry houses, piggeries, and dairy stables to manage ammonia levels and temperature.
-
Commercial Greenhouses: Controlling humidity and heat buildup to prevent crop stress and disease.
-
Large Workshops: Extracting smoke, dust, and general particulate matter from manufacturing floors.
-
Mining Substations: Cooling electrical enclosures and transformer rooms in remote locations.
Installation Notes
-
Aperture Size: This unit requires a square wall opening slightly larger than the fan housing. Ensure the wall structure is reinforced to handle the weight and vibration.
-
Electrical Connection: Given the 1.1 kW rating, ensure the 220 V supply line is appropriately fused. A dedicated isolator switch is recommended near the fan for safety.
-
Air Intake: For maximum efficiency, ensure there are adequate air intake points (vents or windows) on the opposite side of the building to allow for proper cross-ventilation.
