1500 CFM Centrifugal Direct Drive Upblast Exhaust Fans

The CDD Direct Drive Plastic Fans are available in thermoformed PVC, polypropylene, and spark-resistant PPs-EL options. Material selection should be based on the chemical composition and operating conditions of the exhaust stream. Polypropylene is described as chemically inert across most of the pH range, while PVC, polypropylene, and FRP product options support different chemistries and temperatures.

Yes. The product information identifies thermoformed PVC and polypropylene construction with no metal in the airstream. This design is intended for ventilation systems handling corrosive or chemical-laden gas streams where metal components could be vulnerable. Stainless steel support sets and hardware are available outside the airstream as part of the fan construction.

CDD Direct Drive Plastic Fans are identified with a capacity range from 50 to 6,000 CFM and up to 10 inches of static pressure. A 1500 CFM application falls within that stated product range, but the appropriate configuration depends on the complete system requirements, including static pressure, air chemistry, temperature, and installation conditions.

In a direct-drive arrangement, the impeller is mounted on the motor shaft. This removes belt-driven components from the power transmission system and is described as supporting whisper-quiet operation and low maintenance. The product information also identifies bearing life of more than 100,000 hours, while actual service performance depends on operating conditions and maintenance practices.

Yes. The product information lists spark-sensitive or explosive atmospheres as an application environment and identifies a spark-resistant PPs-EL option. The correct material and configuration must be evaluated against the specific process, exhaust chemistry, operating conditions, and applicable safety requirements before selection.

The fans are available in six-position and dual-rotation configurations. Accessories include flexible connectors, flanges, and vibration isolators. These options can help align the fan with the ductwork, airflow direction, and installation arrangement. IPF Colasit can provide product-selection guidance based on the required airflow, static pressure, materials, and system layout.
