  • Description

    S&P DB series Downblast Belt Drive Centrifugal Roof Exhausters are used to expel relatively clean air from many commercial and industrial facilities as well as manufacturing and assembly plants, office buildings, schools and other "clean air" facilities. Roof mounting gives you the opportunity for shorter duct runs, in for the areas or spaces being exhausted, for 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. The DB line offers higher static pressure capabilities which allows for both ducted or non-ducted installations.

    To help eliminate over-tensioning 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 air movers also offer lower sound levels and lower RPMs. The DB20RH1S offers 13.9 Sones @ 0.25 Static Pressure with 875 RPMs. With it's quiet operation, the DB ventilation system is a great choice.

    The housing on the S & P DB20RH1S features heavy-gauge aluminum construction. The housing includes a bird screen, stainless steel exterior fasteners and a disconnect switch. An easily removable cover allows for quick access to the single speed open drip-proof motor for maintenance.

    The DB20RH1S is a size 20 model which means the fan wheel is 20 inches across. With 4,687 CFMs at zero Static Pressure (resistance against air) and a 0.75 horsepower motor, this fan offers operation up to 0.5 static pressure and is rated for round-the-clock use. Tri-voltage (115-208-230) is standard on all 3/4 to 1 1/2 horsepower, single phase motors. DB Exhausters are available in 18, 20, and 24 inch models. Each model offers several hp options from .33 - 2.0 horsepower.
