A motor blower package is the ‘air mover’ in a pneumatic conveying system. In a pressure system, atmospheric air is filtered before entering the system, then that air is powerfully blown through pipes. Dry bulk material enter the airstream from a vessel to be carried to its destination, such as a silo, or surge bin. In negative pressure systems, the air is filtered from the system side and exhausts to atmosphere.

What is a PD Blower Package and What is it Used For?
A Positive Displacement (PD) Blower Package is a system designed to move air through a process by trapping a fixed volume of air and then forcing it into the discharge pipe. There are two main configurations: direct-drive and belt-driven. Let’s explore the components, functionality, and how these blower packages are used across different industries.
Key Components
Blower: The blower is the heart of the system, responsible for generating the necessary airflow to transport materials or provide ventilation. It uses impellers or rotors to draw in air and increase its pressure, directing it through the system with sufficient force to perform the required task. The efficiency and capacity of the blower are critical factors in determining the overall performance of the pneumatic system. PD Blowers generate an enormous amount of potentially damaging heat. PD Blowers have EXTREMELY tight tolerances and fast moving impellers! Because of this, US Systems highly recommends using the absolute best oil available on the market to keep your blower from being damaged. We solely recommend the Gardner-Denver brand PD Blower Oil. It’s expensive, but not as expensive as a new blower!
Motor: The motor powers the blower, converting electrical energy (or another energy source, such as diesel in some configurations) into mechanical energy that drives the blower’s impellers. The motor’s power rating and efficiency directly impact the blower’s performance, ensuring it can generate the necessary airflow and pressure. The choice of motor depends on the specific application requirements, such as speed, torque, and energy efficiency.
Couplings and Belt Drives: Both couplings and belt drives are used to connect the motor to the blower, transmitting the motor’s rotational force to the blower shaft. Couplings can be rigid or flexible, accommodating minor misalignments between the motor and blower shafts, thus reducing wear and tear. Belt drives, on the other hand, use belts and pulleys to transfer power. This method offers greater flexibility in positioning the motor and blower, and allows for easy adjustment of operating speeds through pulley changes. Belt drives also provide a cushioning effect that can reduce shock loads and vibrations, enhancing the longevity of the system components.
Coupling Guard: The coupling guard is a safety feature designed to protect the coupling from external damage and to prevent accidental contact with moving parts. It encloses the coupling, safeguarding against debris and ensuring that operators do not come into contact with the rotating components, which could cause injury.
Inlet Filter: The inlet filter is crucial for ensuring that the air entering the blower is free from dust and particulates. By removing these contaminants, the filter protects the blower and downstream equipment from damage and wear, helping to maintain system efficiency and longevity.
Inlet Silencer: The inlet silencer works to reduce the noise generated by air entering the blower. By dampening the sound waves produced during air intake, the silencer minimizes operational noise levels, contributing to a quieter working environment, which is particularly important in noise-sensitive areas.
Discharge Flexible Connector: The discharge flexible connector connects the blower to the discharge pipe, providing a flexible yet secure connection that accommodates thermal expansion, vibration, and slight misalignments. This flexibility helps to prevent stress and damage to the blower and piping system, ensuring smooth and continuous operation.
Discharge Silencer: The discharge silencer is designed to reduce the noise generated by the air exiting the blower. It dampens the sound waves produced by the high-velocity airflow, minimizing noise pollution and creating a quieter working environment. This is especially important in settings where noise control is crucial, such as residential areas or indoor facilities.
Discharge Check Valve: The discharge check valve is a one-way valve installed in the discharge line to prevent backflow of air into the blower when the system is shut down or during pressure fluctuations. It ensures that air flows in the intended direction only, protecting the blower from potential damage caused by reverse airflow.
Discharge Pressure Relief Valve: The discharge pressure relief valve is a safety device that manages and regulates the pressure within the system. It automatically releases excess pressure to prevent over-pressurization, which could lead to equipment failure or safety hazards. This valve is critical for maintaining safe operating conditions and protecting the integrity of the system.
Discharge Pressure Gauge: The discharge pressure gauge monitors the system pressure at the blower’s discharge point, providing real-time readings of the pressure levels. This information is essential for operators to ensure that the system is functioning within the desired pressure range and to detect any anomalies that might indicate potential issues, such as blockages or leaks.
Functionality of PD Blower Packages
PD blowers provide a consistent flow rate regardless of pressure conditions, making them ideal for applications requiring stable and reliable airflow. They are utilized in various industries due to their efficiency and reliability.
Direct-Drive vs. Belt-Driven Blower Packages
Direct-Drive Blower Packages
- Efficiency: Direct-drive blowers offer high efficiency as the motor is directly connected to the blower, minimizing energy losses.
- Maintenance: These systems typically require less maintenance because they have fewer moving parts.
- Compact Design: Direct-drive packages are often more compact, saving space and making them easier to install in tight spaces.
Belt-Driven Blower Packages
- Flexibility: Belt-driven blowers provide flexibility in adjusting the blower speed by changing the pulley sizes, allowing for a broader range of operational settings.
- Cost-Effective: Belt-driven systems can be more cost-effective initially compared to direct-drive systems.
- Maintenance: They require regular maintenance to monitor and replace belts as needed, ensuring optimal performance and preventing downtime.
