U-Shaped Fan Blade For Direct-Drive Negative Pressure Fan System And Longitudinal Fan System

A direct-drive negative pressure fan is a powerful and efficient ventilation device with several notable characteristics.

Design and Construction

This type of fan typically has a sturdy and durable housing made of materials such as metal or high-quality plastic. The direct-drive mechanism means that the motor is directly connected to the fan impeller, eliminating the need for belts or pulleys. This design results in a more compact and reliable unit.

The fan blades are carefully engineered to optimize air movement. They are often designed with aerodynamic shapes to maximize airflow while minimizing noise and energy consumption.

Functionality

The main function of a direct-drive negative pressure fan is to create a negative pressure environment. By exhausting air from a space, it draws in fresh air from other openings, promoting air circulation and ventilation. This is particularly useful in industrial settings, warehouses, livestock farms, and other areas where good ventilation is essential.

The negative pressure created by the fan helps to remove stale air, heat, humidity, dust, and odors. It can also help to control temperature and humidity levels, improving the overall working or living environment.
