development manufacture and worldwide sale of quality airmoving control and conditioning equipment with totalcommitment to customer service For 40,000 CFM at 0.25” of pressure in a non-ducted application, the prop fan is the right fan for the job. The 54” prop I am showing here has a relatively low FEG value. But a similar prop in a tubular housing with a higher FEG value actually consumes more power.
