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.

Construction and Design

Engineered with durable materials and robust construction to withstand the demands of industrial environments.

Key design elements include:

Propeller Materials

Fabricated from heavy-duty steel or corrosion-resistant aluminum
Aluminum propellers offer lightweight, heat-tolerant, and efficient airfoil shapes
The material choice depends on the application’s specific requirements and environmental factors

Fan Panel and Drive Frame Construction

Manufactured to match the level of duty and motor size
Rugged construction ensures reliable operation and long service life
Designed to minimize vibration and noise levels

Wall Panel Mounting Features

Prepunched mounting holes for easy installation and precise alignment
Sturdy wall panels provide proper spacing between the propeller and wall
Allows for quick and secure attachment to the building structure

Safety Features

OSHA-compliant guards protect personnel from moving parts
Guards are securely fastened and designed to prevent accidental contact with the propeller

The well-engineered construction and design of sidewall propeller fans contribute to their exceptional performance, durability, and safety.

These fans deliver reliable ventilation solutions for various demanding industrial applications. They utilize high-quality materials and adhere to strict manufacturing standards.

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.
