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.

Duct Fans K EC SILEO, Systemair
Art. no.: 66411006
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.

Accessory for wet room fan Pax
Art. no.: 9302371
Various accessories suitable for Pax Fitted series.

back draught shutter Fitted Can be used to avoid air movements in undesired directions during fan installation in ducts without natural circulation (e.g. against an exterior wall). This assumes that another ventilation system handles the building’s basic ventilation flow.
Noskona Pax is installed according to need as a replacement of back draught shutter on the Pax Fitted 31.
All pole switch Fitted According to the standards for household products, EN 60 335-1, can be isolated from the electricity network.
Pax Wall plate Used as a mounting/support frame when the fan doesn’t cover the channel opening and/or when there are issues with screw anchors in the direct vicinity of the channel opening.
Spacer frame Fitted moves the fan 52mm out from the surface, i.e. the same distance that Pax Fitted Fans usually recesses into the ventilation channel. Therefore, together with the spacer frame, it becomes possible to mount the fans in channels smaller than Ø100 mm, or channels where for some other reason it is too cramped for normal installation with an insert.
