1. The GREASE BAFFLE separates grease particles and water vapor
from the air stream by the centrifugal force of the air moving through
its inter-leaved baffle plates. Ejecta is collected in the GREASE CUP
through drain holes in the baffle frame and cabinet.
The GREASE BAFFLE POSITION MONITOR plunger switch controls
electric power to the ventilator fan.
2. The PRE-FILTER is composed of a replaceable media filter and a
filter-retaining gage. The pre-filter captures the bulk of grease vapors.
Pre-filter position is monitored by a vacuum switch, which is in the
control circuit of the cooking appliance contactor.
3. The FILTER PACK is composed of a high-efficiency filter to capture
grease vapors down to a very small particle size; and, an activated
charcoal filter to help control cooking odors.
The FILTER PACK POSITION MONITOR plunger switch is in the
control circuit of the cooking appliance contactor.
