General Description
The REV-LOW hood is used on all single row cooking
equipment lineups, wall mounted. The unit is ceiling
hung with a recommended mounting height of 6'-6"
(1981 mm) from the lower edge of the canopy to the
floor. The ventilator is installed with the core
extractor section over the cook's head. The hood is
finished with a number 4 finish on exposed sides. The
REV-LOW hood is available with fluorescent or
incandescent lights wired to a J-box.
Efficiency
The REV-LOW hood is a revolutionary idea in
commercial kitchen ventilator design. The REV-LOW
allows the exhaust flow to be field adjusted from
90cfm/ft to 450cfm/ft over each appliance without
affecting the overall efficiency of the ventilator. Your
kitchen will exhaust the lowest minimum required
anywhere to ventilate the appliances located under the
hood. After your kitchen is complete, appliances can
be Relocated, Added, or Removed from under the
hood! It's a simple adjustment to fine-tune your

Exhaust and Supply
The REV-LOW hood exhaust calculations are outlined
in the REV-LOW Engineering Manual. The complete
kitchen ventilation system must be balanced, such that
a minimum of 80% continuous heated makeup air is
provided through dedicated makeup air systems or the
kitchen A/C units. It is good engineering practice to
provide this heated fresh air into the kitchen space.
The heated fresh air should not exceed 90 percent of
the total exhaust volume.
