Systemair K 315 L SILEO Centrifugal Duct Fan
Item no. 19514
Description
- Speed-controllable
- Integral thermal contacts
- Can be installed in any position
- Can be installed outdoors
- Maintenance-free and reliable
The K series is designed for installation in ducts. All K-fans have minimum 25 mm long spigot connections.
The fans have backward-curved blades and external rotor motors. The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibration to the duct. The fans can be speed-controlled via a stepless thyristor or a 5-step transformer.
To protect the motor from overheating, the fan has integral thermal contacts with electrical reset. The casing is manufactured from galvanised sheet steel and folded, which gives the fan a close to air-tight casing. Duct connected outdoor and wet room applications of the fan are possible due to the air tight casing.
