Exhaust fans have four designs of wheels.

While dust collectors have been the specialty of N.R. Murphy Limited for decades, the company offers a diverse product range. The portfolio includes a line of exhaust fans, which make employee breathing safer and easier. These devices come with four different types of fan wheels.

Each of these wheels is designed for a specific level of air or material handling for the respective exhaust fan.

Engineered according to exacting specifications

N.R. Murphy exhaust fan wheels run from 12¼ to 64-3/8 inches in diameter, from 3.21 to 16.85 feet in circumference, and from seven to 37 inches in inlet diameter. Outlet areas run from 0.265 to 7.41 square feet, while inlet areas range from 0.258 to 7.27 square feet.

Aiming for the highest standards, the N.R. Murphy team builds its own blades for wheels on exhaust fans, all made according to exacting specifications. The four types of fan wheels:

  • EH. An open wheel for almost any material-handling need, made of extra-heavy steel plate to resist severe shock and abrasion in tasks with high material volumes. Recommended for handling air containing small wood blocks, knots, or paper trims with nose cones in their designs.
  • EHL. With a similar design to the EH’s, but for standard material-handling needs.
  • EM-1. Also like EH, but slightly more efficient, with a back plate and individual blade supports for extra strength and rigidity. The plate stops wood shavings and long, fibrous, or stringy material from wrapping around the blades. Recommended for sawdust chips and similar items.
  • EA-1. The most efficient option, built to withstand high shock and abrasion with high material volumes. With a backward-inclined, radial-tipped design with a coned shroud and back plate for added rigidity, plus a controlled inlet clearance to guide airflow. Recommended for relatively clean air and pulling air through filters and separators, but not for materials.

Exhaust fans are available in a range of sizes and capacities, with fan arrangements for virtually all applications. All are digitally balanced for perfect operation, with optional construction for heavy abrasive materials and spark resistance.
