Aluminium alloy Negative Pressure Direct Drive Fan 1800W For Ventilation
Product Description
This 1800W aluminium alloy negative pressure direct drive fan provides efficient ventilation and cooling through a negative pressure system. By activating horizontal and longitudinal fan systems, the fan creates airflow that exhausts indoor air to the outside, resulting in a reduction of the overall indoor temperature.
Key benefits include:
Cost-Effective: Lower initial investment (approximately one-sixth the cost of air conditioning) and reduced energy consumption (operating costs about one-tenth of air conditioning).
Effective Cooling: Achieves a temperature reduction to approximately 28 degrees Celsius, comparable to air conditioning when using water from water wells.
Improved Air Quality: Provides fresh, moist air with a cleanliness level of up to 99%.
Specifications
Fan Dimensions & Weight: Overall size (diameter, depth, etc.) and weight of the fan unit.
Airflow Rate: Measured in cubic meters per hour (m³/h) or cubic feet per minute (CFM), indicating the volume of air the fan can move.
Fan Blade Material & Design: Details about the aluminium alloy used, the blade shape, and number of blades.
Motor Specifications: Information about the motor type (e.g., direct drive, AC), voltage, frequency, insulation class, and protection rating (e.g., IP rating).
Noise Level: Measured in decibels (dB), indicating the sound produced during operation.
Static Pressure: Measured in Pascals (Pa), indicating the fan's ability to overcome resistance in the ventilation system.
Installation: Mounting options (wall, roof, etc.), ease of installation, and any specific installation requirements.
Lifespan & Maintenance: Expected lifespan of the fan and recommended maintenance procedures.
Applications: Specific industries or environments where the fan is best suited (e.g., factories, warehouses, greenhouses).
Certifications & Standards: Compliance with relevant safety and performance standards (e.g., CE, RoHS).
Features: Variable speed control, automatic shutters, or other special features.
