A roundup of heavy-duty industrial fans to provide air cooling in applications from chemical processing to enclosure cooling.

A pre-engineered, packaged fan, the Design 5500/5800 PBC offers the performance of a special heavy-duty or custom fan without the lead time and costs of a custom fan, says the manufacturer. 

The EnduraDrive incorporates permanent-magnet, direct-drive technology in which the fan motor is directly coupled to the fan, eliminating the need for intermediary moving parts like gears or belts.

Smartpack is engineered to meet stringent low noise and high efficiency requirements in industrial heating, refrigeration and heat exchange applications. Construction of the plug-and-play fan packs includes a custom-configured Multi-Wing fan, an AC or EC motor, a fan guard and a shroud made from a strong metal frame with a plastic skin.

Series PF provide guaranteed NEMA Type 12 protection, says the manufacturer. Filterfans 4.0 reach a particularly high airflow and provide an IP 54, Type 12 system of protection with flow-optimized fins and rotor blades. 

The Air Movement and Control Association (AMCA) International Inc. announced the full revision of AMCA Publication 311, Certified Ratings Program Product Rating Manual for Fan Sound Performance.

A computer-optimized fan blade design provides increased airflow and reduced operating noise.

The B-Wheel backward curved impeller has a seven-blade design (instead of the standard eight) in which the blade diameter is smaller than the outside diameter of the cover and support plate.
