High-Performance Commercial Ventilation

The VKM 220V series is ideal for warehouses, workshops, manufacturing facilities and large commercial buildings requiring reliable supply or exhaust ventilation.

Unlike conventional axial fans, the centrifugal design is well suited to overcoming duct resistance, making these fans an excellent choice for longer or more complex duct systems.

Maximum airflow ratings are at 0" static pressure. Actual airflow depends on duct resistance and system design.

Frequently Asked Questions:

What type of inline fan is best for long duct runs and high static pressure?

Centrifugal inline fans, such as the Vents VKM series, are well suited to long duct runs, multiple elbows and restrictive ductwork. Their backward-curved impellers help maintain airflow against higher static pressure than many conventional axial fan designs.

How do I choose the right VKM inline centrifugal fan?

Start with the required airflow (CFM), duct diameter and system static pressure. The VKM 355Q, VKM 400 and VKM 450 accommodate 14", 16" and 18" ducts respectively. Always compare the fan's performance curve against the system's operating static pressure before selecting a model.

Can a VKM 220V inline fan be used for commercial exhaust ventilation?

Yes. The VKM 220V series is designed for high-volume supply and exhaust ventilation in commercial and industrial buildings. Applications include warehouses, workshops and large facilities requiring continuous airflow. Confirm that the fan is suitable for the specific exhaust airstream and installation requirements.

These 3 models are designed for 220V Commercial or Industrial applications where higher CFM is required. Want to learn more about inline fans? Read our guide to choose the right one with confidence.
