Image and Text Table

With a legacy spanning more than 75 years, AMETEK Rotron is the industry leader in aerospace thermal management, specializing in the design and manufacture of exceptional AC and Brushless DC fans that meet demanding environmental requirements.

We Set the Standard.

Our fans are designed to excel in military and aerospace applications, surpassing specifications for shock resistance, vibration tolerance, humidity control, extreme temperature conditions, moisture protection, salt spray resistance, and electromagnetic interference compliance. Rotron is ISO9001 and AS 9100 certified, and created and released MIL-B-23071, the U.S. military standard for AC fans and blowers.

Customized to Your Specific Application.

We understand that there are instances when an off-the-shelf design may not fully meet the specific requirements of our customers. In such cases, our dedicated team collaborates closely with the customer to gain a deep understanding of their needs. We then assess the feasibility of providing a customized solution tailored precisely to their requirements. At AMETEK Rotron, we are committed to delivering excellence and satisfaction by offering personalized and effective solutions to meet the unique needs of the aerospace and defense industry.

Small Vaneaxial Fans

Small Vaneaxial Fans are compact, high-speed fans whose airflow is parallel to the motor shaft. The impeller and guide vanes are of airfoil construction for maximum aerodynamic efficiency and minimum acoustical noise.

Size Range	1" - 3"
Maximum Speed	33,000 RPM
Maximum Airflow	~120 CFM at Free Delivery

Common Applications
Spot Cooling Smoke Detection Cabin Temp Sensors Avionics & “Black Box” Smoke Extraction & Scavenge Crew Ventilation

Large Vaneaxial Fans

Large Vaneaxial Fans (MAXIAX®) provide high flows against high impedance in a compact axial flow package. They operate at high rotational speeds, typically with 400 Hz motors or internal ECDC brushless motors. MAXIAX® fans are extremely efficient and highly customizable, allowing for precise airflow design.
