Application
Model TUB is designed for high capacity industrial and commercial roof exhaust applications. The remote drive configuration of the TUB is especially suited for the removal of fumes, vapors, steam, dust, smoke and contaminated or heated air. Belt drive models are available for continuous operation in air temperatures to 200˚F. For temperature ratings to 1000˚F and/or IRI requirements refer to Model TUB-HT
Capacities range from 6210 to 60,116 CFM and up to 1" static pressure. Fan selections are available in 24, 30, 36, 42, 48, 54 and 60 inch sizes. Horsepowers range from 3/4 to 15HP. Blade selections are available in aluminum, steel, or fiberglass reinforced polypropylene (see capacity charts for performances). Units are tested in accordance with AMCA 301 (sound) and AMCA 210 (air) in an AMCA certified laboratory. Every unit is completely assembled and factory tested for quality assurance prior to shipment.
Construction
The TUB series is built with heavy-gauge steel to provide years of reliable service. Tubes 24-54" (to 10HP) are G-90 galvanized steel. Size 60" are manufactured from carbon steel, then primed and finished with a grey epoxy paint. Sizes 24-60" have rolled 2" flanged ends.
The TUB series is also available in aluminum construction sizes 24- 48" with welded aluminum angle flanges on each end.
Upblast fans include a heavy-gauge galvanized steel windband with pressure operated damper doors. A galvanized channel section drains water out of the fan area when the damper doors are closed.
All fans are available in epoxy, heresite or polyester resin finishes. Special colors can be ordered. Contact you representative for the cost and finish best suited for your application.

Blades
For versatility, blades are offered in special high-strength, adjustable pitch aluminum airfoil, or adjustable pitch fiberglass reinforced polypropylene. TUB units with special steel blades are available upon request. These styles were selected to provide optimum performance and strength at low to moderate noise levels. Refer to
the performance tables for the best selection.
The adjustable pitch aluminum airfoil propeller performs over a wide range of static pressures. This blade's strength is derived from
matching T-6061 extruded aluminum airfoil sections to a heavy steel plate hub. All Breidert blades are statically and dynamically balanced.
The highly corrosive resistant polypropylene blade's efficiency is due to the uniform twisting of the airfoil section over its entire length, resulting in less turbulence. The operating parameters are -40°F to 185°F ambient temperatures. Hubs are produced from die cast aluminum resulting in a light weight, high strength factory adjustable pitch blade.
Drives
This belt drive model comes with 200,000 hour L50 relubricable pillow block bearings and remote grease lines as a standard feature.
Bearings and drives are isolated from the airstream by bolted, heavy-gauge galvanized belt tubes and bearing covers. Belt drive models through 3HP ship with variable pitch pulleys; over 3HP have fixed pulleys. The motor base slides for easy belt adjustment. All units are factory assembled and test run for quality assurance.
Motors
Motors used in the TUB series are heavy-duty, nationally recognized, with nationwide service centers. Standard motors are open drip-proof (ODP). High efficiency, totally enclosed fan cooled (TEFC), explosion proof, and corrosion duty motors are available as an option.

Specification Checklist
Upblast roof exhausters shall be belt drive Model TUB as manufactured by Breidert Air Products, Jacksonville, Florida. Units are tested in accordance with AMCA Standard 301 (sound) and AMCA 210 (air) in an AMCA certified laboratory.
Fan tubes shall be heavy-gauge, G-90 galvanized steel for 24" through 54" sizes (10HP maximum). Size 60" shall have carbon steel primed and finished in a grey epoxy paint. Tubes 24-60' shall be welded one piece with 2" flanged ends for maximum strength. Bearing plates shall be minimum 10 gauge, G-90 galvanized steel, welded in place and protected from the airstream by welded, heavy-gauge galvanized steel.
Propellers shall be high strength adjustable pitch aluminum airfoil, heavy-gauge steel, or high density, adjustable pitch nylon reinforced polypropylene. (See fan schedule for best selection).
Motors shall be permanently lubricated, sealed ball bearing type by nationally recognized manufacturers. Belt tensioning of the nonstatic, oil-resistant v-belt is to be accomplished with adjustable tension rods. Motors, bearings and belts shall be shielded from the airstream by a sheet metal enclosure. Drives shall be sized for a minimum 150% of drive horsepower. Drives shall be single-belt adjustable sheaves through 3HP; double-belt, fixed sheaves through 10HP, three-belt and fixed sheaves on 15HP units (adjustable sheaves are optional on two and three-belt drives). Bearings shall be heavy-duty cast-iron, pillow block, ball bearing type with remote grease lines and relubricable fittings. Bearings shall be self-aligning, double-sealed and factory prelubricated. Standard bearings shall be designed for minimum 200,000 hour life.
Fan shafts shall be turned, ground and polished steel coated with an anti-rust compound to resist corrosion.
All specifications are subject to change without notice unless
approved in submittal by Breidert Air Products.
