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鈥 w.g., is available in seven sizes from 12鈥 鈥 30鈥 and in CFM ranges from 500 鈥 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鈥 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.
