What are PD Blowers
Positive Displacement Roots® blowers are machines used to move air and gas across various industries, including food & beverage, chemicals, water, pulp & paper, mining, cement, power, metals, and oil & gas. These blowers are crucial in processes such as combustion, vacuum, air separation, water aeration, pneumatic conveying, and membrane cleaning or regeneration.
In gas applications, Roots blowers handle gases like steam, nitrogen, hydrogen, and other hydrocarbons, and are specialized in steel degassing with high vacuum boosters. For vacuum truck OEMs, truck-mounted Roots blowers are ideal due to their quiet operation and powerful performance.
Why Industry Chooses Roots® Blowers
Range: Roots® blowers offer nine models covering a wide performance range. Small rotary blowers can handle up to 6,300 cfm and are available either as bareshaft blowers or within standard packages. Larger blowers can manage up to 70,000 cfm and can be customized as per customer requirements or supplied as bareshaft for external packaging.
Reliability: Known for their continuous use, Roots® blowers are highly reliable. Optional features like Dual splash lubrication can increase oil capacity, further enhancing reliability.
Efficiency: Power consumption is a significant factor in operating costs. Roots® experts ensure the right blower is specified for each application to maximize output while minimizing power usage, leading to cost savings over time.
Noise: Maintaining acceptable noise levels is crucial for the health of on-site personnel and nearby communities. Roots® blowers excel in this area with WHISPAIR™ technology, which reduces pulsation and noise by 3-5 dBA.
Key Features of PD Blowers
- Easy Installation: Designed with a small footprint for straightforward setup.
- Versatile Performance: Capable of operating efficiently across a wide range of conditions.
- Safety and Reliability: Air flow design ensures safety for personnel and reliability of equipment.
- Improved Efficiency: Convenient access to the air filter reduces pressure losses, enhancing blower efficiency and protecting the equipment.
