 Description of axial fan GE404

GE404 is a highly efficient and smooth running axial fan with a rotation frequency of 1400 rpm and a voltage of 230 volts It has a high volume flow of 5000 m³/h and a diameter of 400 mm.

The application fields of the fans are versatile, so they can be used to cool machines, but also to ventilate office spaces. They can also be integrated into smaller generator rooms. The version of the built-in fan, thanks to the powder-coated or galvanized ring, which is made of steel, allows its use in containers. It can also be used in walls of offices and halls.

Voltage and regulation of axial fan GE404

Regulation of AC fans can be easily done at 230 volts by temperature controllers TR46 from our versatile offer.

Many offices use air quality controllers to stimulate air circulation in office spaces. Thus, the fans are also installed in stable buildings.

If the fan is used in a permanently high heat condition, thermal contacts in the form of bimetal switches prevent defects in the motor.

The control voltage of the AC fan is 230 volts and 50 hertz. Voltages for the USA area (480 volts, 60 hertz) and the Canada area (575 volts, 60 hertz) are available, and special voltages of 500 volts and 50 hertz are also possible.

The axial fans can be controlled by robust speed controllers, which are available in the versatile offer catalog of Kaiser Ventilatorenbau in transformer design. This is possible for the fans in the entire speed range.

Speed controllers can also control the 230 volt AC fans electronically and steplessly. In our offer there are also CO2 controllers, temperature controllers and air quality controllers, which can also take over the control.

According to DIN-IEC/TS 60034-17, an all-pole sinusoidal filter must be connected between the motor and the fan, depending on the frequency converter, if the three-phase motors are to be controlled by a frequency converter.

Stainless steel variants of the GE404 axial fan

Stainless steel fans in V2A (material number 1.4301 or AISI 304 or X5CrNi189) can be manufactured for the food industry. Fans in special stainless steel material V4A (material number 1.4571 or AISI 316 or X10CrNiMoTil810) are often used in air with high salt content.

If desired, the motors, which are cast from high quality aluminum, can be left raw or painted for the food industry. If the fans are ordered regularly, a special material approved for the food industry can be used in the production.

Painting with salt water-resistant paint for offshore use is also available.

Material of the GE404 axial fan

Glass fiber reinforced plastic material is the standard for the impellers of Kaiser Ventilatorenbau. For an application field with high temperatures, the product is also available with aluminum impellers.

Rectangular plate fans are also available as a design upon request, but due to cost considerations are only available with a minimum order.

IP54 and IP56 are available degrees of protection, which means that the fans can also be installed in humid areas. However, IP44 is installed as standard.

The air direction of the fans is freely selectable, but must be specified when ordering.

Technical drawing of the axial fan GE404

Reversible is the air direction of the fans due to the flexible design. For optimum efficiency, the plastic axial impeller blades are profiled. This reduces the air flow rate by 15% when the air direction is reversed.
The fans, which carry the high thermal protection class F or H according to DIN EN 60085, are an in-house design by Kaiser Ventilatorenbau and are specially adapted to the AC axial fans.
Type tests for installation and storage temperature are available. Also available are salt water tests for the fans in the offshore area and an IPx6 test of the humidity class.
The fan, which is 100% compliant with the requirements of the ERP2015 Ecodesign Directive (ErP Directive 2009/125/EC EU Regulation No. 327/2011), is designed to be energy efficient and carries the CE mark.
Weather protection dampers and blow-out protection grilles are available in our wide-ranging offer catalog.
CAD data of our products in STEP exchange format are permanently available on our website and ready for download. This makes it possible to easily and quickly include Kaiser Ventilatorenbau products in the design and planning process.
