S & P DB20VH1S Downblast Belt Drive Centrifugal Roof Exhauster - 20" Wheel, 115/208-230 Volt
The DB20VH1S 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 ventilation fans also offer lower sound levels and lower RPMs. The DB20VH1S offers 26.0 Sones @ 0.25 Static Pressure with 1,210 RPMs. With it's quiet operation, the DB ventilation system is a great choice.

It also includes a 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.
