Introduction
Whether installing a new kitchen ventilation system or
renovating an existing one, quality conscious restaurant
owners and designers have insisted on GBD from
Supreme Fan for over 25 years. This exceptional, heavy
duty, curb mounted exhaust blower system is easily
installed, delivers efficient performance and offers easy
access for cleaning and servicing. The GBD, with static
pressure capabilities to 5” w.g., is available in seven
sizes from 12” – 30” and in CFM ranges from 500 –
14,000.
Here are the features which make the Supreme
difference in setting the GBD apart from typical kitchen
exhaust systems:
Heavy Duty Bearings
Bearings used on GBD blowers are durable, self
aligning, pillow-block, ball bearing type with Zerk fittings
for effortless lubrication.
Fan Wheel
The fan wheel is constructed of heavy gauge aluminum
or steel and is backwardly inclined and non-overloading.
The standard Supreme wheel is capable of exhausting
up to 5” w.g. (consult factory for higher static
applications).
The lift-out wheel used on the GBD is counterbalanced
and designed to lift out of the fan assembly. This allows
for easy cleaning and maintenance.
Motor
The motors used on all Supreme Fan products are
energy efficient and are rated for continuous duty
operation. Being completely out of airstream, the motor
is readily accessible for maintenance by simply raising
the motor cover, without the use of tools.
Base
The bases available for GBD blowers are fabricated
from heavy gauge steel and are continuously welded for
strength and durability. Bases are vented and reinforced
at hinging points for extra strength.
Discharge Scoop
The discharge scoop used on the GBD blowers is
continuously welded to the blower housing to prevent
grease leakage. The GBD blower has a very low profile.
Supreme Fan offers a 36" discharge extension, if
needed, to extend the discharge above the roof line.
Grease Reservoir
The unique design of the grease reservoir on GBD
blowers is another part of why these units are Supreme.
Its heavy gauge construction separates it from other
manufacturers; the extra large Supreme reservoir is
designed to separate water from real restaurant grease.
The reservoir is integral to the fan base, continuously
welded liquid-tight, and is designed to handle large
amounts of liquid. Water and snow are allowed to
separate from the grease and run off onto the roof, while
the grease is trapped in the reservoir. The reservoir is
provided with a brass ball valve for ease of draining. The
liquids can be optionally piped to a code-approved
receptor, eliminating the need for rooftop maintenance of
the reservoir.
Funnel Fitting
A funnel to connect ductwork from the fan inlet to the
exhaust duct is available. It is constructed of heavy
gauge galvanized material and is continuously welded to
make a liquid-tight connection to the blower unit. Provide
duct size when ordering.
Housing
The housing is made of heavy gauge steel and is
continuously welded liquid-tight for strength and to
prevent grease leakage. Supreme covers the entire unit
with UL approved high gloss paint to make cleaning easy.
Lifting lugs are factory installed for ease of rigging. The
fan housing is hinged to make access and cleaning of
ductwork simple. The stainless steel hinges pivot the fan
housing and welded steel stops hold the fan in place.
