Air Movement
Across Industries

From HVAC and data centre cooling to clean rooms, tunnel ventilation and process extraction — GTM fans and ventilators deliver precise, reliable air movement in the applications that matter most.

Where We Serve

Engineered for Every Application

GTM axial fans, centrifugal fans, and EC fan units are trusted by engineers, system integrators, and OEMs across Europe for their precise airflow performance and German-engineered reliability.

HVAC and air handling fans
01

HVAC & Air Handling

Axial and centrifugal fans are the heart of every air handling unit. GTM EC and AC fans deliver precisely controlled airflow and low sound power for reliable heating, cooling, and ventilation in residential, commercial, and industrial buildings.

Engineering Advantage

Why GTM?

For more than 55 years, German engineering has set the benchmark for air movement. GTM combines aerodynamic precision, efficiency, and durability that few manufacturers can match.

Energy Efficiency

GTM EC fans are driven by IE5-class motors that meet and exceed ErP 2015 (EU Reg. 327/2011) requirements. Electronically commutated technology and aerodynamically optimised impellers cut energy consumption by up to 50% versus conventional AC fans, while infinitely variable speed control lets systems run only as fast as they need to.

Durability & Reliability

Precision-balanced impellers to ISO 21940, sealed bearings, and IP54 to IP66 ingress protection give GTM fans a service life measured in decades — even in aggressive, dusty, or humid environments. Every unit is built to maintain rated performance under continuous duty, reducing downtime and maintenance costs over the life of an installation.

Quiet Operation

Aero-acoustically profiled blades, low operating speeds, and finely balanced rotors keep sound power levels in dB(A) remarkably low. GTM fans deliver the airflow systems demand without the noise — ideal for offices, clean rooms, residential ventilation, and any environment where acoustic comfort matters as much as performance.
