4-1/2"Ø inlet and outlet.
cools low pressure air streams using fan-drafted ambient air. Ideal
for installation outdoors where cooling water is unavailable or undesirable due to freezing temperatures. Indoor installations should be well ventilated. The process air should be filtered and pulsating flow, such as that produced by rotary lobe blowers, should be dampened by a chambered silencer prior to entering the heat exchanger.
The fan runs well; sounds good. Demonstration video on file.
