CE compliant, ignition proof, marine fan with flows to 1424 CFM [40.3 M3/Min]

CE Labeled with integrated safety guard and reversible hub/blade assembly. Ignition-proof construction, conforms to J1171, ISO 8846 and ISO 9097.

Ideally suited for small vessel engine rooms and OEM applications where compact high flow ventilation systems are required. Excellent for today's high horsepower vessels, the 11-inch Axial Fan provides nearly 9 times the air volume of small DC centrifugal marine blowers with low electrical load requirements.

Design & Construction
The 11-inch Axial Ventilation Fan is specifically designed and built for the rigors of the marine environment. With a flanged shroud made of glass-filled nylon, this unit provides a nearly indestructible, compact fan with superior corrosion resistance. Extended wiring leads from the motor for simple, quick electrical connections. Simply changing motor polarity, removing the hub/shaft clip and reversing the hub allows this fan to be used for "pusher" or "puller" applications.

A specially marinized sealed DC direct drive motor provides quiet, reliable service. Motors are totally enclosed (TEAO), double-shielded, ball bearing type. Constructed with die cast aluminum end plates, O-ring seals, stainless steel shaft and tough black Teflon epoxy coating for superior corrosion resistance. Armatures are dynamically balanced for quiet, vibration-free operation.

Fan Hubs & Blades
A 5-blade glass-filled nylon hub with a pilot is secured directly to the motor shaft.

Black glass-filled nylon with black Teflon epoxy coating.
