  • Description

    The DB20QH1S 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 being 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. 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 DB20QH1S offers 10.7 Sones @ 0.25 Static Pressure with 760 RPMs. If a quiet ventilation fan is your priority, this is the right model for you.

    The housing on the S & P DB20QH1S 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, ODP motor for servicing and repair.

    The DB20QH1S is a size 20 model which means the fan wheel is 20 inches in diameter. With 4,071 CFMs at zero Static Pressure (resistance against air) and a 0.50 horsepower motor, this fan offers operation up to 0.5 static pressure and is rated for non-stop use. DB exhausters with .33 through .50 horsepower motors are rated for 115 volts, single phase connections. DB Exhausters are available in 18, 20, and 24 inch models. Each model offers several hp options from 1/3 hp to 2 hp.

    S&P Downblast Belt Drive Centrifugal Roof Exhausters have a 5 year warranty. They are also AMCA Certified for Air and Sound Performance as well as cULus 705 Listed.
