TYPE “D” GREASE EXTRACTOR
The SPRING AIR SYSTEMS type “D” grease extractor is a
high efficiency dry grease extractor. The type “D” grease
extractor removes grease, dirt and lint through centrifugal
force. Removing the front access door and wipe the interior
with a damp cloth to manually clean the grease extractor
chamber
Principle of Operation
The contaminated exhaust air enters the high velocity inlet
slot A and flows through the transition zone to the VORTEX
CHAMBER B. The exhaust air accelerates through a
complete 270-degree turn around the VORTEX BAFFLE C.
Centrifugal force causes the grease, dirt and lint particles to
deposit on the PRIMARY VARIABLE FLOW BAFFLE G and
VORTEX BAFFLE C. The sloping VORTEX BAFFLE C
drains collected grease to the end of the ventilator into the
grease cup H.
The exhaust air continues into the secondary extraction
chamber, which contains an additional baffle, F. Residual
grease is deposited on the secondary baffle as the exhaust
air gyrates through the secondary chamber.

VENTILATOR GREASE EXTRACTOR SYSTEMS : TYPE “C”, “H” & “D”
SPRING AIR SYSTEMS ventilators are available with either automatic or manual wash systems. All water wash
ventilators must be interconnected with a water wash control panel.
Manual: Type “D” Ventilator
The type “D” incorporates a grease extractor similar to
type “H” but without the wash manifolds. The type “D”
is recommended for light to medium cooking
applications where grease is minimal.
The liquefied grease collects on internal baffles as
described in the “Grease Extractor” section of the
manual. The baffles are designed to drain the
liquefied grease to the end of the ventilator and into the
grease trough and grease cup.
To clean the grease extractor, the front access door
and grease cup are removed and manually washed in
a kitchen sink.
The two interior baffles and grease trough should be
wiped down with a damp cloth soaked in a water and
mild detergent mixture. If the cooking application
generates high temperatures, the grease trough may
require additional cleaning and/or scraping to remove
baked-on solidified grease.
