The DAIN Centrifugal Fan Turns 25!

News » The DAIN Centrifugal Fan Turns 25!

DAIN turns 25! This centrifugal fan is a reference point for industrial ventilation in the Ho.Re.Ca sector. Find out more, read the news.

On the market for 25 years, the DAIN centrifugal fan has become a benchmark in the Italian-made industrial ventilation landscape, ideal for applications requiring the handling of large air volumes in harsh environments with smoke, vapor, and light dust.

Designed to meet the needs of the most complex industrial plants, today DAIN integrates:

High-efficiency IE3 and IE4 motors
Modular design for new installations or retrofit interventions
ATEX Certification, essential for explosion-risk classified environments

All supported by personalized technical consulting to help you find the most suitable solution for your needs.

But DAIN is not the only CMC solution. In this news, let’s look together at how centrifugal fans work and the different types available on the market.

Centrifugal Fans: Function and Technology

The operating principle of centrifugal fans is as simple as it is effective: the impeller or fan rotates at high speed, drawing air from the environment and expelling it outward thanks to the centrifugal force generated by rotation.

This technology enables:

A constant and controlled air flow
A stable pressure within the system
High efficiency in air movement, both clean and contaminated

Understanding how a centrifugal fan works is important for choosing the right model based on the type of air to be treated, working conditions, and the type of system it is to be installed in.

Main Types of Centrifugal Fans

Scroll Fans

Designed for applications requiring a constant and controlled air flow, such as smoke extraction systems, welding areas, or industrial painting lines.

Inline Fans

Thanks to their compact design, they are ideal for confined spaces or systems with articulated ductwork, such as industrial HVAC systems, production halls with multi-level air distribution, or tunnel and underground ventilation systems.

Backward Curved Blade Fans

Robust and durable, these are specifically designed to extract air contaminated with dust, chips, or abrasive particles.

This type of fan is the ideal solution for harsh environments such as woodworking shops, metal processing plants, cement factories, or facilities with high mineral dust presence.

Forward Curved Blade Fans

Offer high air flow, with blades positioned forward for a constant and controlled air stream. Ideal for smoke extraction systems, drying plants, and ventilation in heavy-duty industrial processes.

Customized Solutions by CMC Ventilazione

To meet the diverse needs of each system, CMC Ventilazione offers a wide range of centrifugal fans fully customizable in size and accessories to ensure maximum operational efficiency.

CMC centrifugal fans are tested and certified according to the highest European standards, in compliance with the UNI EN 16798-3 regulation, which defines the air quality requirements in indoor environments and the criteria for proper and safe ventilation in workplaces.

Among our most appreciated solutions, the DAIN model is the preferred choice for its reliability, versatility, and high performance, establishing itself as a reference point for companies active in industrial production and mechanical processing.
