1/2 PROPIMAX 2
The Propimax 2 is Rotron’s most axially compact tubeaxial fan and is equipped with an aerodynamic venturi configured case.  These high speed fans achieve minimum (“½”) size with a shortened venturi configuration utilizing the unique Rotron inverted motor construction the axial length of the fan is limited to the minimum measurement required by the highly efficient 2-blade propeller, with no further space sacrificed for the AC induction drive motor.

Tubeaxial fans are compact and quiet designs for cooling electronic enclosures under severe environmental conditions in airborne, ground based, and shipboard applications where air can move freely with low static pressure.

Airflow Switch
The Rotron Model 2C Airflow Switch is actuated by air velocity rather than air pressure. It is designed for easy mounting on the outside of an air duct with a small light weight stainless steel vane protruding through a hole in the duct into the airstream. The switch can be used as interlock for on off purposes or as a marginal safety device where the electrical contacts are operated at a predetermined minimum flow air.

The switch is designed for commercial applications but has been used satisfactorily on certain military projects. Its acceptability on military projects is left to the evaluation of the purchaser.
Operates reliably in ambient temperatures of  35ºC to +85ºC
.



Centraxial Blowers
Centrimil centraxial blowers have an impeller that, unlike the centrifugal blower, achieves a substantial portion of conversion of velocity energy to pressure energy within the impeller itself. It is operated with a scroll so air enters axially and exits tangentially, making a 90 degree turn. Models are available with 50/60 and 400 Hz AC or brushless DC motors.

Centrimil centraxial wheel blowers develop high pressure and volume performance at low rotational speeds than vaneaxial fans for quieter cooling of tightly packaged electronic equipment under severe environmental conditions in airborne, ground based, and shipboard applications.



Centrifugal Blowers

Rotron centrifugal blowers are compact, sturdy, and relatively light in weight. They are designed for high performance while providig a long, maintenance-free life. Most models are available for either clockwise or counter­clockwise rotation, and in either simplex or duplex types. Models are available with 50/60 or 400 Hz AC motors.

Centrifugal blowers develop high pressure-to-volume performance at low rotational speeds for quiet cooling of tightly packaged electronic equipment under severe environmental conditions in airborne, ground based, and shipboard applications. 

Simplex blowers have 1 squirrel cage impeller wheel while  Duplex blowers have 2 squirrel cage impeller wheels mounted on a common shaft - both are available for either clockwise or counterclockwise rotation. Duplex blowers simplify ductwork and allow greater volume performance in tight locations.  As with all squirrel cage blowers, air enters axially and exits tangentially, making a 90 degree turn.



Fan Heaters/Military Vehicle

To provide a simple solution suitable for retrofit or incorporation into the original environmental control system, AMETEK Airscrew offers a range of fan heaters suitable for military vehicles.

Low Speed Warning Detector (LSWD)
The Low Speed Warning Detector (LSWD) utilizes a programmable frequency switch capable of turning “on” or “off” a load such as a LED, audible alarm, back-up fan, etc., at a predetermined motor RPM. If fan speed falls below the preset value, the back-up or warning device is activated. Once fan speed exceeds the preset value, it is de-activated. The RPM value is preset at the factory to 33% of the nominal speed of the motor but can be set to any RPM desired.  The preset value has a tolerance of ± 25%.
