Speed Controls
The speed controls should only be adjusted by a qualified
certifier.
The speed controls are electronic circuits that allow the certifier to set the speed of
the motors by adjusting their voltage. The PuriCare speed controls are rated for 10
Amps current each, far in excess of the motor's normal current draw, to allow for
greater reliability.
Station Air Intakes (Grilles), Ductwork and
Air Balance Controls
The station’s containment and performance are affected by the location, size, and
pattern of the grilles at the front and rear of the work area.
Never block or obstruct the grilles of the PuriCare.
The internal ductwork of the PuriCare conveys the air from the work area to the
blower, and then from the blower to the filters. The exhaust filter plenum of the
PuriCare is unique in the industry, utilizing perfect manifold technology to deliver
a more uniform airflow to the exhaust HEPA filter, optimizing filter loading and
operational life.
