  • Description

    The DB18QH1S 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. 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. With higher static pressure capabilities, both ducted and non-ducted installations are available options for the DB line of exhausters.

    Belt drives allow for easy adjustments to balance the system. An automatic belt tensioner is available for DB models up to size 24. The addition of this helps to eliminate the risk of over-tensioning the drive components. The 100070 Automatic Belt Tensioner must be ordered at the time of your roof exhauster and it is factory-installed.

    Belt driven exhausters also offer lower sound levels and lower RPMs. The DB18QH1S offers 14.0 Sones @ 0.25 Static Pressure with 940 RPMs. If quiet performance is on your list, the DB ventilation system is a good option.

    The housing on the S & P DB18QH1S features heavy-gauge aluminum construction. The housing includes a bird screen, 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 service.

    The DB18QH1S is a size 18 model which means the fan wheel is 18 inches in diameter. With 3,568 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 round-the-clock 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.

    This model makes for easy replacement of these exhausters: Greenheck GB, Loren Cook ACEB, Pennbarry DX, Carnes VEBX, Acme PV and Fantech 5BDD models.

    Soler & Palau DB Series Exhausters carry a 5 year warranty and are AMCA Certified for Air and Sound Performance and cULus 705 Listed.
