Axial Fans and Types

Axial fans are devices that are rounded by giving a special shape, and round air duct flashes are mounted at the inlet and outlet openings. In these devices, the electric motors are mounted on the device body thanks to the connecting feet with increased strength. Round axial fans are manufactured using galvanized sheets with static paint.

What Does Axial Fan Do?

The task of axial fans is to provide a fast air transfer. These circular cross-section fans can be used with air duct connection or free discharge. Axial blade fans; It can be integrated into jetfan ventilation systems in parking lots. In this way, it is ensured that the collection air reaches the ground level. These devices can serve as both aspirators and ventilators. Axial bladed fans can also be used for the transfer of explosive and flammable materials.

Usage Areas of Axial Fans

Axial fans can be used in all areas where smoke evacuation, air transfer and similar needs are required. The motors of the fans working for smoke evacuation can withstand high temperatures. The smoke engines used in these fans are designed to withstand temperatures up to 300 degrees for at least 3 hours. Thanks to the propellers used in axial blade fans, flow and pressure adjustment can be made by means of angle adjustment. Blades with adjustable angle are produced using bakelite and aluminum materials.

Axial fans are especially preferred in cooling towers, dusty areas, facilities where explosive and flammable gases are used, and acidic environments. In addition, the ventilation need in long tunnels can be met by these fans. Axial fan types can also be used in foundries, industrial facilities, workshops and kitchens where high suction is needed.

Advantages of Axial Fans

Axial fans, which have a very practical use, offer economical solutions. Air duct counter flanges offer quick and easy mounting. It can also be used as an axial aspirator and ventilator by changing the mounting direction.

In these fans, the propellers are directly coupled to the motor shaft. In this way, there is no loss of efficiency due to power transmission mechanisms. In terms of the requirements of the project, the desired amount of pressure and flow can be adjusted precisely thanks to the angle adjustable blades. When necessary, it can be used in ventilation and smoke evacuation processes by using a two-speed electric motor.

Axial Fan Types

The main reason why radial and axial fans differ from each other is that the movement of the air created by pressure in axial fans is in the axial direction. In radial fans, this happens in the direction of the centrifugal force. Axial fan types are considered in three different groups. These are propeller blade type, roller blade type and guided roller type axial fans. Axial fan types are very practical and easy options in terms of assembly. The types of these fans, which are extremely successful in terms of energy efficiency, can be explained as follows;

  • Impeller Blade Type Axial Fans: This fan type; It is widely used in low, medium and high pressure general heating systems. In addition, this type of fans are also used in ventilation systems and air conditioning applications.
  • Cylinder Blade Type Axial Fans: These fan types are used in low and medium pressure general heating systems. In addition, cylindrical bladed fans are also used in the exhaust systems of the cabins where drying and painting processes are carried out.
  • Guided Cylinder Type Axial Fans: These fan types are used in low static pressure and large air flow rates.

Silent Axial Fans

These fans, also known as silent axial fans, are used in ventilation processes. It is possible to find different models of silent axial fans. These models generally differ according to their size, that is, their efficiency. Model variety can be in different standards. The biggest advantage is that it works silently. Silent axial fans operating at low decibel ranges provide ambient isolation. These fans, which can be mounted on walls or ceilings, can also be fixed on glass surfaces.

Practical and silent, this type of axial fans provide the conversion of ambient air. Quiet fans, which provide extremely efficient and fast air circulation, can reach temperatures up to 40 degrees. In addition to heating and cooling, these fans can also be used in air conditioning. In general, they have a water-resistant structure. For this reason, they are widely used in areas such as bathrooms, kitchens and toilets. In addition to these, it is very suitable for use in industrial facilities. They help to clean the air, especially in environments where flammable and explosive materials are present.

Axial Fan Models

It is possible to access dozens of different axial fan models with ERF. Thanks to its wide product range, you can easily find a fan model that suits your needs. Axial fans, which are important devices in terms of providing air flow, have different features. When choosing an axial fan, you must first determine your needs. After that, you can choose the type and model.

AKAP model is a directly coupled, sleeved option with aluminum propeller. AKAP has sleeved fan blades that can meet high pressure losses and high air flow rates. The material of manufacture of these propellers is aluminum. The fact that the blade angles are adjustable provides the opportunity to change the flow and pressure. Depending on your needs; They can be produced with engines that can withstand temperatures of 200, 300, 400 degrees for 2 hours.

Axial sleeve plastic propeller fan (AKPP) can meet high air flow rates and pressures. The impeller of the sleeve fans is produced from PVC materials. Thanks to the adjustment of the blade angles, flow and pressure changes can be made.

The four-bladed axial sleeve metal impeller fan can provide high airflow rates. AKMP, which performs this process successfully thanks to its metal propellers, can be manufactured as resistant to high temperatures according to demand.

This fan can be expressed as an axial fan with 4 blades and metal rollers. There is the possibility of mounting on the wall and window. They provide low noise level and strong airflow. It stands out as an economical option.

One of the distinguishing features of this axial fan with four blades and metal blades is that it has a square case. ADMP, which can be mounted on the wall and window, provides strong airflow.

Axial fan with seven blades metal propeller can be mounted on walls and windows. These fans are economical options that provide high efficiency.

ERF-ADYP is an axial fan option with 7 blades metal propeller and square case. This option, which provides strong airflow, offers the possibility of mounting on the wall and window.

Round axial fan (EST) can be easily mounted on walls and windows. Reaching high airflow rates, this device has low sound levels. EST is mostly used for ventilation of industrial areas such as factories, warehouses, paint shops, workshops. It is known as an industrial type axial fan.

Square cased axial fan (EKST) can reach high air flow rates at low sound levels. These fans, which are practically mounted on walls and windows; It is widely used in warehouses, paint shops, workshops and factories.

Axial fan (HKAF) with cell sleeve aluminum propellers can meet high air flow rates and pressure losses. The propellers of these sleeve fans can be produced from aluminum castings. In these fans with adjustable blade angles, the cabinet is insulated with 20 mm thick foil rock wool. In addition, they operate extremely silently and can be produced with a motor that can withstand temperatures of 200 to 400 degrees for 2 hours, depending on demand.
