MODEL TUB-HT
TUBEAXIAL UPBLAST PROPELLER ROOF EXHAUSTER
FOR HEAT AND SMOKE REMOVAL
1 year fan housing warranty, 1 year motor warranty
MODEL OVERVIEW
Model TUB-HT has been designed and tested for emergency heat and smoke removal. This design
also lends itself to everyday nonemergency high capacity industrial and commercial roof exhaust
applications. Model TUB-HT successfully passed heat test of 1000°F for fteen (15) minutes, and
500°F for over four (4) hours by an independent testing agency. Model TUB-HT exceeds I.R.I (Industrial
Risk Insurers) guidelines and is UL-793 Listed as “Power Ventilator for Smoke Control Systems.”
The heavy-gauge design allows for years of standard commercial use and the dependability required
in a re emergency. The upblast conguration exhausts heat and smoke high above the roof line aiding
in the access and capabilities of re ghters. Unlike complete design dependence on gravity vents
which are sometimes limited by air temperature and wind velocity, the TUB-HT in conjunction with
gravity vents, will more effectively remove smoke, hot air, and gases when used in a properly designed
system. In the event of electrical failure, the 165°F fusible link will activate the spring assisted damper
doors to provide gravity ventilation. Fan CFM, sizing and location for both exhaust and supply air are
an important part of the overall heat and smoke venting building design needs. Refer to I.R.I., NFPA
(National Fire Protection Association), and local re codes for help in proper system design. Final
approval for the complete system design should be authorized by the local authority having jurisdiction.
Fan selections are available in 24, 30, 36, 42, 48, 54 and 60 inch sizes. Horsepower and CFM range
to 57,000 CFM and 15HP. Units are tested in accordance with AMCA Standard 301 (sound) and AMCA
210 (air) in an AMCA certied laboratory. Every unit is completely assembled and factory tested for
quality assurance prior to shipment.
