Duct Fan

D-KTF Rectangular Duct Type Fan with External Motor; D-KTF external motor rectangular duct type fan is manufactured from high quality corrosion resistant galvanized steel. Fans are radial fans with backward curved blades driven by the motor outside the air flow. It is suitable for working in conditions that will adversely affect the engine, thanks to the fact that the engine is out of the air flow. The D-KTF series is the ideal choice for high performance and trouble-free operation. It can be used in all kinds of industrial, office, kitchen and residential ventilation where compact solutions are needed.

D-KTF series rectangular duct type radial fans with external motors are the most ideal fans for ventilation systems where it is desired to provide fresh air to the environment or to exhaust unwanted air from the environment. Thanks to their compact structure, they can be mounted directly to the air ducts in any required position. D-KTF duct fans have high performance and trouble-free operation.

The body is made of high quality galvanized steel resistant to corrosion. Optionally, it can be manufactured from stainless steel. The fans used are backward curved radial fans with rare blades. The motors are single-phase or three-phase, with IP55 and Class F insulation. The motor is mounted outside of the air flow. In this way, the device is resistant to continuous operation at 120°C. All models are suitable for frequency inverter. Optionally, it can be manufactured with Exproof feature. It can be used in all kinds of industrial, office, kitchen, hotel, residential and parking ventilation systems where the fluid is hot or corrosive. They can be mounted directly to the air ducts in any position needed.

D-KTF Rectangular Duct Type Fan with External Motor and Technical Specifications

Duct type fans are easily mounted on the wall, floor and ceiling with the mounting feet that come out without an additional console. The fan wheel is directly connected to the motor. Fans with dynamic and static balance work silently and without vibration. The enclosure is made of electrostatic paint coated galvanized sheet. The series of duct type fans has a wide range of applications. It is generally used to meet the need for fresh air and exhaust air for comfort ventilation. The rotor can be plastic or metal depending on use.

D-KTF duct fans have high performance and trouble-free operation. Thanks to their compact structure, they can be directly connected to the duct without the need for large elbows and converters.
