A positive displacement blower - also known as a rotary lobe 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.
Roots positive displacement and rotary lobe blowers provide a set volume of air per rotation, making them ideal for applications where steady airflow is crucial, such as pneumatic conveying.
Roots blowers are renowned for their robust design and resilience in harsh environments. Their construction ensures that they continue to operate with minimal maintenance, reducing downtime and operating costs.
With pressure ratings up to 18 PSI and vacuum capabilities down to 27"HgV, Roots blowers are highly versatile for a wide range of industrial uses.
Roots 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.
Roots positive displacement and rotary lobe blowers are available through our global distributor network, supported by a range of parts, maintenance, and custom solutions tailored to your needs.
