What are PD Blowers
Positive Displacement Roots® blowers are machines that move air and gas in many industries. These include food and beverage, chemicals, water, pulp and paper, mining, cement, power, metals, and oil and gas. These blowers are important for several processes. Combustion, vacuum, air separation, water aeration, pneumatic conveying, and membrane cleaning or regeneration processes use them.
In gas applications, Roots blowers manage gases such as steam, nitrogen, hydrogen, and other hydrocarbons. Designers have specially crafted them for steel degassing with high vacuum boosters. For vacuum truck OEMs, truck-mounted Roots blowers are ideal because 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.
They come as bareshaft blowers or in standard packages. Larger blowers can manage up to 70,000 cfm. You can customize these to meet customer needs or supply them 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 they choose the right blower for each job. This helps increase output and reduce power use, which saves money 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.
