AMETEK ROTRON BLOWERS
For over 60 years Rotron has maintained its position as an industry leader in providing AC and brushless DC blowers, meeting the most stringent performance and environmental specificati*** such as shock, vibration, humidity, temperature extremes, salt spray, moisture and EMI, for military and aerospace applicati***. In situati*** where an existing design will not meet the customer's requirement, we will work with our customer to determine the specific requirements and evaluate the feasibility of offering a customized solution to satisfy the customer's need.

Rotron Centrifugal Blowers
|

Centrifugal blowers develop high pressure-to-volume performance at low rotational speeds for quiet cooling of tightly packaged electronic equipment under severe environmental conditi*** in airborne, ground based, and shipboard applicati***. Simplex blowers h***e 1 squirrel cage impeller wheel while Duplex blowers h***e 2 squirrel cage impeller wheels mounted on a common shaft - both are ***ailable for either clockwise or counterclockwise rotation. Duplex blowers simplify ductwork and allow greater volume performance in tight locati***. As with all squirrel cage blowers, air enters axially and exits tangentially, making a 90 degree turn. All models are built to applicable military specificati***.
Brushless DC Operation and Frequency Converters
Centrifugal Blowers are ***ailable for single or multiple operati*** from DC power sources. Rotron also provides Frequency Converters to allow higher or lower motor speeds, where required, than are possible with a 50/60 or 400 Hz sources. Converters are also ***ailable to operate single or multiple units.
Performance Sensors
All Models equipped with optional performance sensors send out a tachometer-type signal generated from a hall sensor activated by a ***all permanent magnet mounted on the rotor of the fan motor. The signal depends on the fan type:

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 an LED, audible alarm, back-up fan, etc, at a predetermined motor RPM. If fan speed falls below the present value, the back-up or warning device is activated. Once the fan speed exceeds the present value, it is deactivated. The RPM value is preset at the factory between 2,000 and 20,000 RPM (actual value is determined by the specific fan performance and customer requirements).
Inverted Blowers
Inverted Blowers h***e their driving motor located inside the squirrel cage wheel. This results in unusual compactness and excellent motor cooling. Such an arrangement is only feasible whenever the wheel diameter is large in proportion to the volume of air moved. This situation may be obtained in slow volume of air moved. This situation may be obtained in slow running blowers as well as in tight scroll squirrel cage blowers that h***e a high pressure-to-volume ration performance.
