The 4-68 Series Centrifugal Ventilator Fan is a forward-curved blade design built for indoor air circulation in commercial and industrial spaces. It delivers consistent airflow at static pressures typical for ductwork systems, with the series commonly rated for volumes between 500 and 50000 m³/h depending on impeller diameter and motor configuration. The unit operates at noise levels under 75 dB(A) at 3 metres, making it suitable for environments where acoustic comfort is a priority.
Construction uses galvanised steel or aluminium alloys for the impeller and scroll casing, providing resistance to corrosion in standard indoor conditions. The series is available in single-inlet or double-inlet configurations, with motor power ranging from 0.75 kW to 22 kW for typical industrial applications. Bearings are grease-lubricated and sealed to reduce maintenance, while the impeller undergoes dynamic balancing to minimise vibration during operation.
This fan serves warehouses, workshops, and large office buildings where mechanical ventilation is required to maintain air quality. Buyers in manufacturing, logistics, and commercial real estate use it for general exhaust, supply air, or as part of HVAC systems. The unit is designed for easy integration with rectangular or round ducting, and the supplier can confirm compatibility with specific duct sizes and pressure requirements upon request.

Before ordering, verify the exact airflow and static pressure requirements for your application, as performance varies by model and configuration. Request the fan’s performance curve to confirm it meets your system’s demand, and check compatibility with your ductwork dimensions and materials.
Confirm logistics details such as lead time, shipping method, and Incoterms, as these are not specified in the listing. FOB or CIF terms may apply, and the supplier can clarify packaging, crating, and handling requirements for international transport. Payment terms should also be discussed to align with your procurement process.
Inspect the fan upon arrival for damage, and verify that the impeller and casing materials match the ordered specifications. Request a test run to confirm noise levels and vibration, and check that all documentation, including material certificates and balancing reports, is provided. For critical applications, consider third-party inspection before shipment.
