The STXB-UL762 models are upblast belt driven centrifugal exhausters. They are listed for both general applications and suitable for restaurant applications*. The STXB12RHULQH1S is a size 12 model, with a fan wheel of 12 inches in diameter. It features heavy duty construction and is rated for continuous use. The fan wheel is constructed for maximum efficiency featuring aluminum construction and a backward-inclined curved centrifugal wheel. It is dynamically balanced for long lasting, smooth operation. Model STXB exhausters are best suited of removal of dirty, contaminated and/or high temperature air. Uses for the STXB exhausters include restaurant hood and similar kitchen exhaust ventilation, fume and smoke removal as well as laboratory fume hood exhaust and chemical process exhaust. For grease removal applications, fan must be installed per NFPA 96 with a 40" discharge height and hinged access base
The STXB12RHULQH1S can be used in a ducted or non-ducted installation, either vertically through the roof or horizontally through a sidewall. These installation possibilities allow for shorter duct runs and therefore the exhauster can be installed near the area to be ventilated. The STXB12RHULQH1S will produce 1989 CFMs at zero static pressure.
The motor is a single speed open drip-proof motor. The cover is easily removed for maintenance. The housing includes stainless steel exterior fasteners and a disconnect.
An automatic belt tensioner is available. The addition of this helps to eliminate the risk of over-tensioning the drive components. The 100070 Automatic Belt Tensioner must be ordered at the time of your roof exhauster and it is factory-installed.
