Motor/Blower

The motor/blower assembly pulls room air into the front of the cabinet, and re-circulates

it internally. During its recirculation, the air is split into two separate streams. One path

leads through the exhaust HEPA filter and out of the unit. The second path flows

through the supply HEPA filter, which then flows down through the work area, as shown

in Figure 5-4. The motor in the cabinet is an electronically commutated motor (ECM).

The ECM is a brushless DC motor that includes its own power supply to convert the

incoming alternating current to direct current, as well as its own microprocessor to

control and measure the motor's operation. The motor utilizes Labconco's exclusive

Constant Airflow Profile

(CAP) program to deliver a consistent volume of air,

throughout the life of the cabinet.
