The DB18RH1S is just one item in the line of S&P Downblast Belt Drive Centrifugal Roof Exhausters. DB roof exhausters are used to remove relatively clean air from many types of commercial facilities. These include, but are not limited to, manufacturing and assembly plants, office buildings, schools, bathrooms, garages, general non-grease kitchen areas and other "clean air" facilities. 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. 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 DB18RH1S offers 17.8 Sones @ 0.25 Static Pressure with 1,075 RPMs. With it's quiet operation, the DB ventilation system is a great choice.
The housing on the S & P DB18RH1S features heavy-duty aluminum construction. An included bird screen will help to protect the fan. It also includes a stainless steel exterior fasteners and a disconnect switch. The cover is easily removed for convenient access to the single-speed, open drip-proof motor for repair and service.
The DB18RH1S is a size 18 model which means the fan wheel is 18 inches across. With 4,080 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 continuous use. Tri-voltage (115-208-230) is standard on all .75 through 1.5 horsepower, single phase motors. The Downblast Belt Drive Exhausters offer several hp options within each fan size.
