Radial Fan Blowers

An axial fan moves air primarily parallel to the fan shaft, while a radial or centrifugal fan draws air into the impeller and redirects it outward. Radial fans are commonly selected for ducted systems and applications requiring pressure against resistance. The appropriate design depends on airflow, static pressure, gas chemistry, installation arrangement, and required construction material.

IPF Colasit products are available in fiberglass-reinforced plastic, PVC, polypropylene, and spark-resistant PPs-EL configurations, depending on the product family. These materials are intended for corrosive or chemical-laden gas streams and can support metal-free airstream requirements. Material selection should account for the process chemistry, operating conditions, temperature, airflow, and any spark or explosion-protection requirements.

The product range is used in wastewater treatment plants, chemical plants, metal finishing process lines, pulp and paper mills, semiconductor and PCB manufacturing, laboratory fume hoods, air pollution control scrubbers, dust collection systems, and industrial exhaust applications. Specific fan construction and drive configuration should be selected according to the environment and ventilation system design.

Thermoplastic and FRP radial fan blowers are designed for ventilation involving corrosive gases and chemical-laden airstreams. Polypropylene, PVC, and FRP options provide different resistance characteristics, while accessories such as Teflon seals or enhanced veil systems may be available for particular requirements. Confirm compatibility with the process chemistry and operating conditions before selecting equipment.

Available configurations include direct drive, belt drive, and in-line or roof-mounted arrangements across the product range. Direct-drive designs mount the impeller on the motor shaft, while belt-drive fans support a different equipment arrangement and service approach. Installation orientation, airflow, static pressure, access, and maintenance requirements should guide the configuration selection.

Selected IPF Colasit blower and fan models are available with spark-resistant PPs-EL construction, graphite impregnation, spark-proof construction, or explosion-proof motor options. These features are product-specific and must be matched to the application. Review the atmosphere classification, process hazards, fan arrangement, motor requirements, and applicable system specifications with a qualified design professional.
