Duct Fan KVK SILENT 100-160 EC, Systemair
Art. no.: 66421060
KVK Silent EC 100-160 is a fan with circular duct connections. Previously replaces KVKE EC. The casing is made of galvanized steel sheet, insulated with 50 mm thick high-density mineral wool insulation for best sound absorption and fire-engineering requirements with an inner surface layer that prevents the spread of fibers to the air. A screwed service door with hinges makes cleaning and servicing the fan simple. KVK Silent EC comes with integrated motor protection as well as integrated manual control which is pre-connected in the junction box in the form of a potentiometer that can control the fan 0-100%. The fan can easily be controlled on demand via sensors and control for eg. CO2, temperature, moisture, presence and VAV. See accessories list. The fan can be installed in any position. FK mounting clamp (accessory) enables easy installation and disassembly and prevents the transmission of vibration to the duct. • Low noise level, high density insulation • Compact design • Easy installation, maintenance and service • EC motor with high efficiency and low SFP • Adapted for demand controlled ventilation

Art. no.: 66411003
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.

Duct Fan PRIO, Systemair
Art. no.: 6511149
The Prio fan is designed for installation directly to circular ducts. The fan housing is made of Alu zinc. Prio can be demand controlled via sensors and control for CO2, temperature, humidity, presence and VAV etc. or manually with eg. steplessly with a thyristor or a 5-step transformer.
To protect the fan, the fan motors have integrated thermal contact with extended conductors to be combined with a separate motor cover to break the mains voltage in the event of overheating. Motor protection must always be switched on for warranty to apply. Engine covers are integrated in some of the fan control units (see instructions for each controller) or as separate accessories.
• Compact fan with dense design • High efficiency and low SFP • Low noise level • Speed adjustable • Easy installation, maintenance and service • With mounting brackets • Integrated thermal contact

Duct Fan PRIO EC, Systemair
Art. no.: 6511182
EC fans are very energy efficient and easy to control. They have integrated electronics in the engine, which means that the engine always works optimally. They can be controlled speedlessly to match the airflow requirement. With EC motors, they use considerably less energy than fans with AC motors, for the same air flow. The PrioAir series is intended for duct mounting. All fans in the series have at least 25 mm long connection socket (EN 1506: 1997). The fan wheels have aerodynamically optimized blades and guide rails. The engine cover is integrated into the engine electronics. The airtight casing is made of a special composite material (Density class C according to EN12237: 2003). To facilitate installation, mounting brackets (prio mounting bracket) and mounting brackets (FK) are recommended, which makes mounting / disassembly easy and prevents vibration transfer to duct. For installation in wet rooms, we recommend using a timer that ventilates the space for a certain amount of time, or a humidity control that gives a 0-10V control signal to the fan. The fans come with a pre-coupled potentiometer (0-10V) which makes it easy to set the desired working point. • EC motors, high efficiency • Low SFP • 100% speed adjustable • Integrated potentiometer for speed setting in the junction box • Integrated motor protection
• Can be mounted in any position • Compact design • Low noise level

Duct Fan IRE AC, Östberg
Art. no.: 6611701
IRE is equipped with a radial fan with forward or backward angled blades on the fan wheel. It tolerates high pressure with a low noise level. IRE is also available with one or two double pulling radial fans. 50 mm of insulation also means that the fan can be in the cold rooms. The swing out design facilitates cleaning and the fan’s design prioritizes function, durability and life. The stable chassis has been manufactured entirely of galvanised steel sheet. The outer rotor engine is reliable, maintenance-free and high quality.
All IRE are rpm adjustable 0-100% by voltage and frequency control. All IRE have approved thermo-contact engine protection as standard, and can also be supplied with an extensive thermal contacts, for example, for emergency operation (standard on the 3-phase fans).
