The difference between industrial and commercial grade fans construction is the following: Industrial equipment is specifically designed and built to stand up to the rigors of an industrial application. The differences are concrete and easy to spot...if you know what to look for. Tenderall Fan designs and builds equipment strictly for industrial applications and has been doing it that way for over 100 years. Industrial fans and blowers are constructed of heavier duty materials and with higher quality components than their commercial counterparts. When properly applied, industrial equipment can withstand vibration, high and low temperatures, fumes and corrosive gases, materials in the airstream, and many other situations in an industrial environment. The equipment is built to provide longer service life, thus decreasing the need and frequency for replacements. Because industrial fans are expected to last longer, they are designed to be easy to install and maintain.

The best way to see the difference between an industrial product and a commercial product is to compare them feature for feature, including product weights. ...
... In the below example we’ll look at commercial panel fans versus Tenderall Fan industrial panel fans. The commercial grade panel fan has sheet metal, riveted blades, and a riveted hub. Tenderall Fan industrial panel fans have a solid, one-piece cast aluminum airfoil propeller or a cast aluminum adjustable pitch propeller. Lighter fans sometimes have balance weights clipped, bolted, or welded to the back of the fan blades, which can fly off during operation. Tenderall Fan cast aluminum propellers are precision ground and balanced, and therefore require no balance weights.

Another difference between the commercial and industrial fan is in the aerodynamic design. Tenderall Fan originally developed the air seal venturi to improve performance. With this design, the propeller is larger in diameter than the venturi opening, thus creating an air seal. This design eliminates back flow of air pressure and increases air delivery by 10% or more. The way most other panel fans are designed, the propeller is smaller than the venturi opening. This type of fan is easier to manufacture, but significantly less efficient. The basket fan provides even less value because of the air that is lost around the sides of the fan. A Tenderall Fan venturi design fan pushes the air velocity from the blades out the front of the fan for increased spread and throw versus a commercial type fan.

There are also installation differences to consider when purchasing a panel fan. Many commercial fans are shipped in parts. The motor and accessories may be shipped loose and must be assembled to the fan when received. In addition the commercial fan shown on the previous page has no provision for panel mounting or for accessory mounting. This means holes for bolts and mounting hardware must be drilled even before it can be completely assembled or installed. Tenderall Fan panel fans are shipped completely assembled and ready to install. A large selection of industrial fans are available from the stock program for quick shipment, including panel fan ventilators. You can be sure that Tenderall Fan equipment will provide many years of continuous service in your industrial air moving environment !
