Propeller Wall Fan, aka Sidewall Propeller Fans

Sidewall propeller fans, also known as propeller wall fans, are designed to efficiently exhaust or supply high volumes of air at low static pressures in various commercial and industrial settings.

These robust fans are ideal for applications such as:

  • Factories and warehouses
  • Greenhouses and agricultural facilities
  • Parking garages and vehicle maintenance areas
  • Gymnasiums and large event spaces

Propeller wall fans offer a cost-effective general ventilation, heat removal, and air circulation solution. They are available in a range of sizes and configurations to meet the specific needs of different industries and facilities.

Types and Configurations

Propeller wall fans are available in two primary drive configurations to suit different performance requirements and maintenance preferences:

Direct Drive

  • The propeller is mounted directly on the motor shaft
  • Offers maximum efficiency and minimal maintenance
  • Ideal for applications requiring continuous operation or limited access for servicing

Belt Drive

  • The propeller is driven by a belt and pulley system connected to the motor
  • Allows for flexibility in fan speed adjustment
  • Suitable for applications with varying airflow demands or when precise speed control is necessary

In addition to drive types, propeller wall fans can be configured for either supply or exhaust airflow:

Supply Configuration

  • Draws fresh air from the exterior and introduces it into the building
  • Helps maintain a positive pressure environment and reduces infiltration of outside contaminants

Exhaust Configuration

  • Sidewall propeller exhaust fans removes stale, hot, or contaminated air from the interior and expels it outside
  • Wall mounted propeller exhaust fan prevents buildup of harmful fumes, dust, or excess heat within the facility

By selecting the appropriate drive type and airflow configuration, users can optimize the performance of their wall mounted propeller exhaust fan to meet specific ventilation requirements while ensuring efficient and reliable operation.

Performance Specifications

Propeller wall fans offer impressive performance capabilities to meet the ventilation needs of various industrial applications:

CFM Range

  • Delivers airflow up to 50,000+ CFM for larger belt-driven models
  • Accommodates the ventilation requirements of spacious facilities and high-volume applications

Maximum Static Pressure

  • Operates effectively against static pressures typically ranging from 0.5 to 0.75 inches of water gauge
  • Overcomes resistance from ductwork, filters, and other system components

Efficiency and Maintenance

  • Direct drive fans provide high efficiency and require minimal maintenance
  • Belt drive fans allow for flexible speed adjustment but may necessitate more frequent belt tension checks and replacement

By offering a wide range of airflow capacities and the ability to overcome static pressure, sidewall propeller fans can be selected to match the specific performance requirements of the application.

The choice between direct drive and belt drive sidewall propeller wall fan configurations allows users to prioritize efficiency, maintenance, or speed control based on their operational needs.
