Blowers


Model A Centrifugal
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.

Trimline Inverted
Inverted Blowers

Trimline inverted blowers are compact, sturdy, and relatively light in weight. Inverted blowers have the unique Rotron inverted drive motor located inside the squirrel cage wheel. This results in unusual compactness and excellent motor cooling. Models are available in in a variety of Brushless DC and  AC (50/60 or 400Hz) voltages.

Trimlines are compact and quiet designs for cooling electronic enclosures under severe environmental conditions in airborne, ground based and shipboard applications. They are well suited for applications when it is desirable to have air exit tangentially from a thin blower package and high pressure to volume ratio performance is required.

GCENTRIMIL
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.

Model R Type 201 Radial
Model R Type 201 Radial

Model R simplex radial blade blowers (2") are compact, sturdy, and relatively light in weight, designed for development of high static pressures.  Simplex blowers have a single impeller wheel and are available for either clockwise or counterclockwise rotation. As with all radial blade blowers, air enters axially and exits tangentially, making a 90 degree turn.  Models are available with 50/60 or 400 Hz AC or brushless DC motors.

Radial blade blowers produce a higher pressure-to-volume ratio at higher speeds than is obtainable from the centrifugal blower. it particularly suitable for cooling tightly packaged airborne electronic equipment and ventilating NBC protection system filters and particle separators.

Multistage Blowers

Multistage designs range in size from 8 to 14 inch diameters.  They employ the principle of several radial blade wheels mounted on a single shaft to develop uniquely high pressure-to-volume ratios at low rotational speeds by cascading pressurized air from one wheel to the next.  Unusually compact and light in comparison to conventional multistage turbines, these blowers operate quietly and efficiently and contain no sliding or reciprocating parts.  Models are available with 50/60 or 400 Hz AC motors.
