Positive Displacement Blowers
12 products
Positive displacement blowers, known as rotary lobe blowers, efficiently draw air in through an inlet and compress it with rotating lobes to propel it forward. Ideal for moving large air volumes through piping, they excel in applications requiring higher pressure or vacuum levels compared to regenerative blowers. Commonly used in pneumatic conveying, surface cleaning, and dairy milking systems, these blowers are essential for creating precise pressure and vacuum conditions.

Vertical Bottom Hand Positive Displacement Blowers
Vertical axis positive displacement air blowers feature vertically aligned rotating lobes with a bottom-mounted drive shaft. Designed for efficiency, these blowers have horizontally positioned inlet and outlet ports on each side. Ideal for seamless integration, they serve as perfect replacements for Roots-type blowers.
