Duct Fans K EC SILEO, Systemair
Art. no.: 66411008
EC fans are very energy efficient and easy to control. They can be controlled speedlessly to match the airflow requirement, potentiometer supplied. For the same air flow, they consume considerably less energy than fans with AC motors. EC motors contribute to large reductions in energy use, especially in speed control. In speed control the energy consumption of the EC motor is much lower than for an asynchronous motor with a corresponding power. Reduced energy use guarantees lower operating costs. The K EC series is intended for duct mounting. All K-fans have at least 25 mm long connection socket. To facilitate installation, the K-fans have pre-assembled mounting brackets as standard. FK bracket makes mounting / disassembly easy and prevents vibration transfer to duct. The fans have backward curved blades and maintenance-free outer rotor motor (EC) and are supplied with a pre-coupled potentiometer (0-10V), factory set to 6-10V. To protect the motor from overheating, the fans have integrated motor protection. The casing is made of galvanized steel sheet and is folded, which provides a close to airtight casing.

Fresh Air Vent Fresh TL100DE T NEW
Art. no.: 9302642
Fresh fresh air vents are installed in bedrooms and living rooms. A rule of thumb for the correct number of vents is one in each bedroom and two in the living room. In some cases, it is wise to increase the number of vents if multiple people sleep in the same room or if the total living area is larger than usual. The Fresh TL DE series are sleek wall vents. TL DE comes standard with condensation protection, storm protection, and is also paintable. The vent has a telescopic function of 185-340mm; for thicker walls, extend with modular pipes. Installation/Placement The vent is placed high up on the wall, approximately 220 cm from the floor or with the top edge of the vent at least 10 cm from the ceiling.

The vent is excellent for use with underfloor heating. In this case, place the vent at least one meter from the window to prevent cold drafts due to cold radiation through the window. The vent should be placed directly above the heating element. This utilizes the rising heat from the radiator, known as convection current. Comfortable air distribution The air distribution is carefully developed; the vent releases air upwards and to the sides.

The outside air mixes very effectively with the room air, and just a few decimeters from the vent, the incoming air has reached a comfortable temperature. Storm protection saves energy Regardless of the weather, the storm protection slows down high airflows, which contributes to lower heating costs compared to a traditional vent. The storm protection provides good comfort in the room and reduces the risk of drafts.

Filter and maintenance Maintain good indoor air quality by regularly changing and maintaining your filters. To ensure good air quality and maintain flow, the filter should be cleaned or replaced one to two times per year. The standard filter is washable; use a mild soap solution. The pollen filter and electrostatic filter should be replaced with new ones. The filter is mounted in a filter holder behind the front. The front can be easily folded up for access to the filter holder. When using the electrostatic filter, the filter holder is replaced and cannot be combined with storm protection.
