What is a Positive Displacement Blower?
A positive displacement blower is designed to deliver a consistent air volume with each rotation, regardless of changes in discharge pressure. This characteristic makes it indispensable for applications requiring a reliable airflow under variable pressure conditions, ensuring steady, efficient performance across industries.
Advantages of Positive Displacement Blowers
Consistent Airflow
Positive displacement blowers provide a set volume of air per rotation, making them ideal for applications where steady airflow is crucial, such as pneumatic conveying.
High Reliability and Durability
Models like the Roots blowers are renowned for their robust design and resilience in harsh environments. Their construction ensures that they continue to operate effectively with minimal maintenance, reducing downtime and operating costs.
Adaptable Pressure Range
Positive displacement blowers are designed for pressures (up to 18 PSI) and can even manage vacuums down to 27"HgV, making them versatile for a broad spectrum of industrial applications.
Compact and Efficient
These blowers often have a compact footprint, allowing for easy integration into existing systems, especially when space is limited. This also aids in simpler installation and maintenance, further enhancing their value.
Availability and Support
Positive displacement blowers, including the renowned Roots blowers, are readily available from suppliers, often in stock for prompt shipment. These suppliers provide a comprehensive range of services, including parts, maintenance, and custom solutions tailored to your needs.
ROOTS Positive Displacement Blower Series
ROOTS Universal RAI Rotary Positive Displacement Blower
This heavy-duty blower features detachable, steel mounting feet, enabling flexible installation in both vertical and horizontal orientations. Its rugged cast-iron construction, coupled with alloy steel timing gears and oversized bearings, makes it ideal for continuous, demanding industrial use. The dual lubrication system ensures long-lasting performance with minimal maintenance.
ROOTS RAM Rotary Blowers
Known for durability, the RAM series integrates ductile iron impellers, gray iron casings, and aluminum drive covers to optimize weight and resilience. The RAM series utilizes cylindrical roller bearings and a unique hydrodynamic seal to minimize maintenance, making it perfect for intensive, uninterrupted applications.
ROOTS RCS Rotary Positive Blowers
Built similarly to the RAM series, the RCS blowers use gray iron for all primary components. These blowers come with splash oil lubrication, and adaptable mounting feet, ensuring durability and easy adaptability for various installation setups.
Why Choose Positive Displacement Blowers?
Compared to fans and compressors, positive displacement blowers like Roots blowers offer medium pressure with exceptional durability and reliability. These units excel in industrial applications that require constant airflow without interruptions due to pressure fluctuations. This dependable performance ensures process consistency and superior product quality.
