VDI Series Ducted Axial Fans

VDI Series – High efficiency and flow for industrial and civil ventilation

VDI axial fans, manufactured by SA NU VENT, are designed for moving air, gases, vapors, or smoke within industrial and general ventilation systems.
With a ducted design, these fans ensure simple and efficient integration into ductwork systems, providing constant airflow and stable pressure even at high flow rates.

The VDI series is intended for applications where strong air circulation is required, with minimal pressure losses and continuous reliability, even in slightly corrosive environments or with a moderate load of vapors and fumes.

Industrial and civil applications

VentilVentilatoarele axiale intubate VDI sunt potrivite pentru o gamă largă de domenii:

Industrial halls and production workshops – general ventilation and hot air removal;
Warehouses, commercial spaces, and underground parking lots – recirculation and exhaust of stale air;
Paint booths and finishing lines – exhaust of light fumes and vapors;
Civil ventilation – technical spaces, gyms, tunnels, transit areas.

With their compact construction and proven performance, VDI fans are the ideal choice for exhaust, air conditioning, or controlled cooling systems. They are the ideal solution for complex production flows.

Construction and technical characteristics

Casing: made of galvanized steel sheet, ducted, with anti-corrosion protection;
Impeller: made of corrosion-resistant polypropylene, ensuring durability and perfect balance;
Mounting: directly on the ventilation duct or on industrial walls, with quick fixing;
Motor: single-phase or three-phase, IP 54 protection, designed for continuous operation;
Airflow temperature: up to 60°C;
Ambient temperature range: between –15°C and +30°C;
Restrictions: gases must not be explosive or flammable.

VDI fans offer acoustic stability, reduced energy consumption, and a smooth pressure curve, making them ideal for applications where constant flow is essential.

Available series

VDI axial fans are available in two main versions:

🔹 Single-phase fans (VDI-M) – for standard ventilation and air conditioning applications;
🔹 Three-phase fans (VDI-T) – for extensive industrial systems, with continuous operation.

Each model is available in a variety of diameters (350 mm – 550 mm) and powers (0.12 kW – 3 kW) to meet the specific requirements of each type of installation.

Key advantages

High airflow with minimal pressure losses;
Compact construction and easy to integrate into existing systems;
Increased resistance to corrosion and wear;
Low noise level during operation;
Simple maintenance and long service life.

Proven performance in industrial ventilation

The VDI series is the result of over 40 years of experience in developing high-performance and energy-efficient industrial ventilation solutions.
Through the optimal combination of power, flow, and reliability, these fans have become the main reference for applications in which such equipment is suitable.
