Product catalog summary

Overview: The document provides detailed information about Systemair's circular duct fans, specifically the K-fan and KD fan models, highlighting their reliability, airtightness, performance, and ease of installation.

Specifications:

The K-fan models range from diameters 63 to 315 mm, meeting European Standard EN 1506:1997 for spigot length and EN 60335-2-80 for thermal contact with electrical reset.
The KD fan models are designed for larger air volumes, suitable for ducting between 315-500 mm, and feature a mixed flow fan impeller for increased airflow.

Features and Benefits:

Both fan types offer easy installation with mounting brackets and FK mounting clamps to prevent vibration transfer.
The fans are speed controllable via transformer or thyristor and are suitable for wet environments due to their airtight casing.
Systemair provides a three-year guarantee on these products.

Performance Data:

Airflow rates for K-fan models range from 135 m3/h to 1640 m3/h depending on the model and static pressure.
KD fan models offer airflow rates from 1870 m3/h to 8030 m3/h, catering to larger air volume needs.

Installation and Accessories:

Fans come with a mounting bracket and cable gland included.
Accessories available include diffusers, draft dampers, silencers, filter cassettes, heaters, transformers, and thyristors.

Design and Construction:

The K-fan features a compact design with a sealed casing to prevent leakage and an 8 mm neoprene lining to suppress vibrations.
The KD fan utilizes an external rotor motor cooled by the transported air, allowing for voltage regulation of motor speed.

Range 250 - 500 mm • Compact design • High capacity • Low noise Mixed flow fan The KD fan is quite simply a continuation of the K-fan and designed to handle larger air volumes. Because of the relationship between pressure and air flow of radial fans with backward-curved blades, this fan type is not suitable for circular duct fans above diameter 315 mm. KD is a mixed flow fan, i.e. the fan impeller is a combination between a radial and an axial impeller. It gives considerably more airflow than radial fans and is the best fan impeller type for 315-500 mm ducting. The possibilities for tailor made...
