Efficient ventilation plays a vital role in maintaining optimal air quality and comfortable working conditions in commercial settings. Reversomatic, a renowned manufacturer, has revolutionized the commercial fan industry with their cutting-edge technology and innovative designs. In this comprehensive blog post, we will delve into Reversomatic’s RBD (Belt Drive Model) and RDD (Direct Drive Model) tube axial fans, focusing on their features, applications, and differences.
Reversomatic Commercial Fans Overview
Reversomatic offers a range of tube axial fans designed for low to medium pressure ducted applications. The RBD and RDD models are versatile options that excel in removing contaminated air or hot air found in industrial applications. Additionally, they can be used to supply air through ductwork for cooling or pressurizing interior spaces, such as elevator shafts and stairwells in condominiums. These tube axial fans are known for their compact design and ability to move large volumes of air in duct systems with relatively low-pressure losses.
Construction and Features of RBD and RDD Models
The RBD model represents Reversomatic’s Belt Drive Model, where the motor and drive assembly are positioned outside the airstream. The housing of the RBD fan is constructed using heavy gauge steel, providing durability and longevity. The propeller blades are made of extruded aluminum and mounted in a cast aluminum hub. Reversomatic ensures that all propellers are statically and dynamically balanced for vibration-free operation. RBD tube axial fans are available in various sizes, offering a range of CFM (cubic feet per minute) options from 1,300 to 70,000, with static pressure ranging from 0 to 3″ SP.
On the other hand, the RDD model represents Reversomatic’s Direct Drive Model, where the motor is positioned within the airstream. The RDD fan shares the same heavy gauge steel housing as the RBD model. The direct drive configuration eliminates the need for belts and pulleys, making the fan more compact. RDD tube axial fans offer CFM options ranging from 800 to 44,000, with static pressure capabilities ranging from 0 to 3″ SP.
Both RBD and RDD models utilize grease-lubricated ball bearing pillow block type bearings with a minimum average life of 40,000 hours. The tube axial fans are equipped with external grease fittings for easy lubrication. Reversomatic ensures that all fans bear the AMCA seal for sound and air performance. The steel sheet metal parts are cleaned, conditioned, and painted with enamel paint finish prior to assembly, with a final coat of gray enamel applied to all exterior surfaces.
Applications and Benefits of RBD and RDD Tube Axial Fans
Reversomatic RBD and RDD tube axial fans find applications in various commercial and industrial settings where efficient ventilation is essential. These fans excel in removing contaminated air and hot air, creating a safer and more comfortable working environment. In industrial applications, they effectively remove pollutants and heat, maintaining optimal working conditions. Additionally, RBD and RDD tube axial fans are suitable for supplying air to cool or pressurize interior spaces like elevator shafts and stairwells in condominiums.
One notable difference between the RBD and RDD models is the positioning of the motor. The RBD model has the motor and drive assembly located outside the airstream, while the RDD model places the motor within the airstream. This difference affects the installation and maintenance of the fans. Direct drive units, such as RDD models, provide easy access to the motor through adjacent ductwork, whereas belt drive units, such as RBD models, require careful consideration of motor positioning for service and adjacent objects like walls and ceilings

Installation and Mounting Options
Reversomatic RBD and RDD tube axial fans offer flexible installation and mounting options to suit various requirements. These fans can be mounted in any position using mounting brackets for ceiling suspension, support legs for floor mounting, or angle supports for rod hangers. To facilitate wiring and service, it is recommended to ensure easy access to the motor. For direct drive units like RDD models, access through adjacent ductwork is ideal. For belt drive units like RBD models, motor positioning should consider service access and adjacent objects. Access doors are provided for convenient maintenance and servicing.
The steel housing of RBD and RDD tube axial fans has flanged ends, allowing for convenient mounting directly in the duct system. Flexible connections or transition pieces can be utilized to reduce noise transmission, simplify duct attachment, and provide access to the fan’s interior.
