The company bases these wheel and fan-arrangement designs on decades of experience in manufacturing these industrial fans for a full spectrum of industries. The versatility of these designs allows users to apply the fans in various dust-control and air-handling tasks, with tested and proven specifications. N.R. Murphy makes these fans with top materials according to these exacting specifications, making the housing with heavy gauge steel and bracing it with steel angles. The team also welds the scroll wrap continuously to the side plates to create a dust-tight, rugged casing.
A major factor in N.R. Murphy exhaust fans is balances wheels, dynamically and statically balanced for smooth operation. These are carefully designed, tested, and built to give superior performance. The heavy-duty, self-aligning pillow block bearings are fastened securely to a strong plate pedestal.
Many sizes and types of N.R. Murphy exhaust fans are available. For heavy-duty material handling, the company recommends Model EH, while Models EM-1 and EH-1 are suitable for light-duty handling and Model EA-1 works best for air. All of these centrifugal blowers can handle air at temperatures up to 315 degrees Celsius. Fan charts, based on standard air of 0.075 density, can help customers select the air pressure and volume.
Exhaust fans work for various industrial applications, whether replacing other fans, connected to dust collectors, or used alone for air and materials. N.R. Murphy also offers various fan accessories and construction options for heavy abrasive material or spark resistance. Also available are heavy-duty fans in stock and ready for shipment, and the company can quickly change or custom-build fans for specific applications.
