Dry Screw Blowers IQCB / IQHE for Industrial Low‑Pressure Applications

Dry Screw Blowers IQCB / IQHE – Gardner Denver

The IQCB / IQHE dry screw blower line from Gardner Denver redefines low‑pressure air performance in critical industrial applications. Designed to deliver high energy efficiency, low noise levels and simplified maintenance, these blowers stand out in wastewater treatment, pneumatic conveying and continuous industrial processes.

Dry screw internal compression technology significantly reduces energy consumption when compared to traditional lobe blowers. The IQ package integrates an acoustic enclosure, optimized silencers and front and side service access, ensuring fast installation and easy maintenance—even in blower rooms with limited space.

Manufactured in Latin America (Brazil), IQCB / IQHE blowers offer high regional availability, competitive lead times and local technical and commercial support, making them ideal for operations across Brazil, Mexico and the broader Latin American region.
