1000 CFM Direct Drive Exhaust Fans

The CDD Direct Drive Plastic Fans are available in PVC, polypropylene, and spark-resistant PPs-EL construction. Material selection should reflect the chemicals, temperatures, and operating conditions in the exhaust stream. Polypropylene is chemically inert across most of the pH range and resists acid and caustic attack through the full wall thickness rather than relying on a coating.

In a direct drive design, the impeller is mounted on the motor shaft. This arrangement avoids belt and pulley components, helping provide whisper-quiet operation and reducing routine maintenance requirements. The appropriate motor, rotation, position, and configuration should be selected according to the ventilation system and operating conditions.

A spark-resistant PPs-EL option is available for applications requiring spark-proof construction. The system designer should review the airstream, process hazards, installation requirements, and applicable safety criteria before selecting a fan. Product suitability should be confirmed with IPF Colasit during the specification and quotation process.

The product information identifies a capacity range from 50 to 6,000 CFM, with configurations supporting up to 10 inches of static pressure. A 1000 CFM application falls within that stated range, but actual operating performance depends on static pressure, system design, fan configuration, and motor selection.

Available accessories include flexible connectors, flanges, vibration isolators, and stainless steel support sets and hardware. Accessories can help connect the fan to ductwork, manage vibration, and support installation requirements. The correct combination depends on the system layout, mounting arrangement, and selected fan configuration.

Direct drive construction eliminates belt-related maintenance, while the product information identifies a bearing life of more than 100,000 hours. Thermoplastic construction also supports corrosion resistance in harsh chemical environments. Maintenance requirements still depend on duty cycle, airstream conditions, installation quality, and the operating environment.
