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" 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. Installation should be on a flat, solid surface capable of bearing the weight and vibrations. The DB line offers higher static pressure capabilities which allows for both ducted or non-ducted installations.
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 air movers also offer quieter sound levels and lower RPMs. The DB18VH1S offers 31.0 Sones @ 0.25 Static Pressure with 1,480 RPMs. With it's quiet operation, the DB ventilation system is a great choice.
The casing on the S & P DB18VH1S 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 DB18VH1S is a size 18 model which means the fan wheel is 18 inches in diameter. With 5,618 CFMs at zero Static Pressure (resistance against air) and a 2.00 horsepower motor, this fan offers operation up to 0.5 static pressure and is rated for continuous use. Tri-voltage (115-208-230) is standard on all 3/4 to 1 1/2 horsepower, single phase motors. The Downblast Belt Drive Exhausters offer several horsepower options within each fan size.
