S & P DB18SH1S Downblast Belt Drive Centrifugal Roof Exhauster - 18" Wheel, 115/208-230V
S&P DB series Downblast Belt Drive Centrifugal Roof Exhausters are used to eliminate relatively clean air from many commercial and industrial facilities as well as manufacturing and assembly plants, office buildings, schools and other "clean air" buildings. It mounts on the roof which allows it to be near the area to be ventilated. With a closer proximity to the ventilating area, shorter duct runs help to create more efficient operation. This DB roof exhauster installs into a 24.75" roof opening. When installing the exhauster on a roof, caution must be taken to assure that the roof is capable of supporting your unit. With higher static pressure capabilities, both ducted and non-ducted installations are available options for the DB line of exhausters.
To help eliminate over-tightening your BD belt driven exhauster, a factory-installed Automatic Belt Tensioner is available. This allows for easy performance adjustments, when necessary, to balance your system. The 100070 Automatic Belt Tensioner must be ordered at the time of purchase.
Belt driven exhausters also offer quieter sound levels and lower RPMs. The DB18SH1S offers 21.0 Sones @ 0.25 Static Pressure with 1,165 RPMs. With it's quiet operation, the DB ventilation system is a great choice.
