Fans for High Flow, High Pressure Applications
High pressure backward-inclined fans are designed to handle both clean air and lightly particulate-laden or moist-air gas streams in applications such as process cooling, food processing, thermal oxidation, combustion air and quench cooling. Model BC-2200 can be used in process temperatures from -50°F (-45°C) to more than 1000°F (538°C). It can be constructed using special alloys such as Hastelloy, Inconel or Carpenter 20 to meet application demands. The fan reaches a volume of 60,000 cfm [(101,940 m³/hr)]. It is available as standard in both belt-drive and direct-drive configurations, with arrangements 4, 3S1 and 7S1 available on request. Standard design features allow for pressures to 65" wg (16,175 Pa) and temperatures to 800°F (427°C). Sensor systems and controllers can be added to maximize efficiency and output, minimize power usage and energy costs, and reduce long-term operating expenses and downtime.

Computer-Optimized Blade Design Provides High Efficiency
The EMAX4 blade profile has a computer-optimized blade design for maximum performance and is designed to reduce energy consumption in air-cooled condensers, refrigeration, chillers, cooling towers and evaporators. The customizable fan can reduce noise emission by 2 to 3 dB. Engineered to fit the company’s existing range of hubs, the glass-reinforced polyamide fan blade works with the company’s modular system with variable pitch angles. This unique profile is available in 5-, 6-, 7-, 9- and 12-bladed configurations with a diameter range of 22 to 36".

Designed for Applications on Air-Cooled Heat Exchangers, Cooling Towers
Operating in air-cooled heat exchangers and cooling towers, heavy-duty fans keep liquids cool in refineries, power plants, process plants and gas compressors. The Class 10000 Heavy Duty has been strengthened in proportion with the increased duty for engine drive and larger fan diameter applications. It has a hub-tube diameter of 3" for added strength and durability. Features include resilient blade mounting, increased chord width, adjustable blade angle, reduced fan ring depth and adjustable diameter. The fan is available in both odd and even blade configurations with up to 16 blades.

High Airflow Fans for Thermal Management
Series PF provide guaranteed NEMA Type 12 protection, says the manufacturer. Filterfans 4.0 provide an IP 54, Type 12 system of protection with flow optimized fins and rotor blades. The fans have a four-corner fastening system that allows the filter medium to be replaced quickly. The fluted filter mat’s folded structure facilitates airflow while the closed frame prevents unfiltered air from penetrating the cabinet. Options include NEMA Type 3R/4/4X / IPx6 washdown or rain hoods, UV protection and EMC shielding. Eight types with capacities from 17 to 560 cfm are offered.
