Overview
The drum version is built to sit in a ring around a finned coil. The impeller draws or blows air across the coil face, and the ring holds the fan at the right distance from the fins — which is why the mounting, not the airflow, is usually what decides the model.
The range covers several diameters and motor speeds. Because these fans run for long periods in refrigeration equipment, the bearing and the ambient temperature at the fan matter more than the free-air airflow figure.

Selection and installation notes
Check the ring diameter and the blade clearance before ordering. A fan that does not seat on the ring pulls air around the coil instead of through it.
Ice, condensate and defrost cycles affect the fan as much as the air temperature. Tell us the application so the bearing and protection can be matched.
FAQ
How do I choose the ring size?
Measure the coil face and the mounting ring, then match the impeller diameter so the coil is covered without dead areas at the corners.
Can it be mounted horizontally?
Depends on the bearing and the condensate path. Tell us the orientation before ordering.
What about defrost cycles?
They matter. Ice on the blades unbalances the fan, so the defrost strategy and the fan position should be considered together.
Is a replacement available for an existing unit?
Yes, if the diameter, pole count and ring match. Send the label or a photo with a tape measure.
