Soler Palau makes various types of ventilation. The DB line of Downblast Belt Drive Centrifugal Exhausters install on the roof of your "clean air" facility. Facilities such as manufacturing and assembly plants, schools, gyms and athletic facilities, hospitals and office buildings are considered clean air facilities. Eating establishments can also use this type of fan in non-grease areas. 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. The DB line offers higher static pressure capabilities which allows for both ducted or non-ducted installations.
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.
