Axial Fan Types

Fan Selection Tool

Axial fans from Ø250 to Ø2000 mm with aluminum or composite impellers, AC/EC motors, ATEX, VFD-ready and marine versions. Wall, duct or free-standing mounting with multiple coatings and accessories. Standard flange-mounted duct fans and wall-mounted fans can be selected online with the Fan Selection Tool.

AV series

Flange-Mounted Duct Fans

The AV axial fan is installed directly into the ventilation duct by means of flanges. Its compact design and efficient performance make it an ideal choice for ventilation applications in process industries, industrial halls, and commercial buildings such as shopping centers.

AVW series

Wall-Mounted Fans

The AVW model is designed for wall-mounted applications where efficient ventilation is required without ductwork. This axial fan is an ideal solution for factory halls, warehouses, and other large spaces where wall-mounted airflow control is needed.

AVR series

Reversible Axial Fan

AVR is a special axial fan model capable of operating in both directions, allowing effective airflow control across a wide range of applications. This makes it an excellent solution for tunnel ventilation, process industries, timber drying kilns, and other applications where reversing the airflow direction is required.

AVB series belt-driven axial fan with the motor mounted above the casing

AVB series

Belt-Driven Axial Fan

In the AVB model, the motor is positioned separately from the fan casing, making it particularly suitable for applications where the air temperature is so high that the motor’s standard cooling would not be sufficient.

The belt drive also provides greater flexibility in adjusting fan speed and power.

This axial fan is an excellent choice for high-temperature industrial applications and specialized ventilation systems.

AVC series

Cased Axial Fan with Motor Cooling Shroud

AVC is the ideal choice for applications where hot air flows through the duct, where the airstream contains particularly corrosive substances, or where the motor needs to be protected from contact with the air inside the ductwork.

The AVC motor is flange-mounted inside a separate sealed enclosure within the fan casing, preventing it from coming into contact with the process air. The enclosure is also ventilated through, providing additional cooling for the motor.

AVX series contra-rotating axial fan in a flanged casing with the AgniVent logo

AVX series

Contra-Rotating Axial Fan for Maximum Performance

When exceptionally high airflow and pressure are required, the solution is a twin axial fan, also known as a contra fan. This special configuration combines two axial fans in series, providing a significantly higher pressure rise and greater air-moving capacity.

It is an ideal choice for demanding industrial applications and special installations where a conventional axial fan does not provide sufficient performance.

Why Choose AgniVent Axial Fans?

We do not tie every project to a single production location. Manufacturing is selectedaccording to the application, required configuration, project budget, delivery scheduleand proximity to the customer — helping us keep both cost and lead time under control.

Impellers

Selecting the correct impeller material is essential to ensure reliable performance, durability and compatibility with the operating environment.

Blade Materials

PAPolyamide

Lightweight and durable; a good choice for general use.

PAGGlass-reinforced polyamide

Greater strength and stability for high-performance duty that demands superior mechanical properties.

AluminumHigh specific strength

Corrosion-resistant, and an excellent choice for high-performance and high-temperature applications.

PACASCarbon-fiber-reinforced polyamide

Conductive and flame-resistant, suited to explosive environments such as mining. ATEX declaration on request.

PAGAFRFlame-retardant glass-reinforced polyamide

Flame-resistant and compliant with fire-safety standards EN 45545-2 and NFPA 130, for safety-critical applications.

SteelHigh mechanical strength

Robust and durable

Blade Profiles

Airfoil

Highly adaptable and well suited to demanding engine cooling and HVAC systems. Efficient, stable at high RPM and cost-effective.

Sickle

Engineered for low noise while keeping efficiency high. Best where consistent pressure and low energy use matter.

Circular Arc

For tight spaces with limited mounting access, giving high airflow while coping with significant resistance.

Broad Circular Arc

Produces substantial airflow at low speed, ideal for cooling and air-conditioning applications.

And more sophisticated designs.
