DR is the standard industrial ROTRON series for continuous pressure or vacuum service in normal, non-classified environments. DR series blowers use cast aluminum housing, cover, impeller and muffler tower with removable cast iron flanges, TEFC motors on single-ended models and ODP on double-ended and spa blower models, and permanently sealed motor bearings rated at 20,000 to 25,000 hours. Made in the USA and BABA compliant.

When DR is a good fit

General aquatic equipment rooms, aquaculture aeration, hydroponic and aquaponic systems, filter air scour, commercial spa and water-feature applications, and other locations without unusual corrosion exposure or hazardous-area requirements.

Selection note

Choose the specific model from its performance curve at the required operating point. Confirm airflow, friction loss, pressure or vacuum, voltage, phase, inlet temperature, altitude and installation environment before ordering.
