Tubeaxial Fans Centrifugal Blowers Finger Guards

Ametek Rotron is an industry leader in providing AC and Brushless DC fans, meeting the most stringent performance and environmental specifications such as shock, vibration, humidity, temperature extremes, salt spray, moisture and EMI, for military and aerospace applications.

Centrifugal Blowers

Rotron Centrifugal Blowers are compact, sturdy, and relatively light in weight. They are designed for a long, maintenance-free life. Most models are available for either clockwise or counterclockwise rotation, and in either simplex or duplex types. Duplex blowers simplify ductwork and allow greater volume performance in tight locations. Models are available for AC or DC power.

Tubexial Fans

Tubeaxial Fans are integrated axial flow air moving devices in which the motor rotor is cast inside the impeller to achieve the smallest possible axial dimension. All Tubeaxial Fans are finely balanced to meet the requirements of MIL-B-23071.

Finger Guards

All finger guards are Stainless Steel (SS), Electro-Polished (EP), with UL spacing (UL).
