FAQs of Nicotra Forward Curved Centrifugal Fan ADH 250 R:
Q: How should the Nicotra ADH 250 R Centrifugal Fan be installed?
A: The fan is base-mounted, making it suitable for secure installations on flat surfaces. Position it in a clean, non-aggressive atmosphere, connect it to the power source (230 V, 50 Hz), and ensure sufficient space for air intake and discharge as per the dimensions 340 x 250 x 290 mm.
Q: What applications is this fan best suited for?
A: This model is ideal for ventilation in HVAC systems, air handling units, and other applications requiring clean air movement. It is specifically designed for use in non-corrosive, non-aggressive atmospheres found in commercial, industrial, and institutional settings.
Q: When is maintenance recommended for the ADH 250 R fan?
A: Routine inspections are advised on a quarterly basis to ensure optimal performance, especially checking for dust accumulation, proper bearing lubrication, and electrical connections. The ball bearing design and corrosion-resistant housing typically require minimal maintenance.
Q: Where can the ADH 250 R fan be used safely?
A: It can be used anywhere indoors where clean air is required, such as inside buildings, plant rooms, or in protected HVAC installations, provided the ambient temperature remains between -20C and +60C and the environment is non-aggressive.
Q: What benefits does the forward curved, double inlet impeller offer?
A: The forward curved, double inlet impeller design ensures higher airflow rates at lower noise levels, making it extremely efficient for ventilation needs demanding both capacity and quiet operation.
Q: How does the fans corrosion-resistant and galvanized housing enhance its longevity?
A: The galvanized and corrosion-resistant fan housing protects the unit from environmental wear and chemical exposure in acceptable atmospheres, supporting a life span of up to 10 years even with continuous use.
