Marine Duty Fans and Blowers - Hartzell Fan - #9

Series 39 M Adjustable Pitch Marine Duty Duct Fans

The Hartzell Series 39 M Adjustable Pitch Marine Duty Duct Fan is best suited for applications requiring high flow and low to medium pressure at temperatures not exceeding the motor rating where adjustable pitch blades allow fans to be accurately set. Propellers are high efficiency and quiet. Low Speed Ultra Quiet selections can reduce sound levels by 5-10 dBa.

• Stable Performance - Wide range in flow volume from low to high blade angle settings.

• Sizes - Available in sizes 16", 18", 24", 30", 32" and 36" for AL props and 40" and 48" for AA prop. Performance from 2,200 CFM to 59,000 CFM at free air and pressures from 0" SP to 2>2" SP.

• Housings - Housings are steel heavy-duty welded construction and are flanged and punched for easy duct connection.

• Axial Impellers - Assemblies are cast aluminum with steel hardware. True airfoil design blades with varying twist and sweep to move air evenly across the entire blade length to reduce system effects. Cast aluminum hub with split taper lock bushing as standard to insure secure mounting to shaft. Multiple blade configurations allow precise selection and performance can be adjusted in the field by change of blade angle if necessary.

• Motors are TEAO or TEFC Marine duty, certified to meet IEEE 45, USCG approved, 50°C ambient below deck type as standard, or per customer specifications.
