FAQ
Can a "whirlybird" be used on top of a braai?
No, it is not recommended as the high temperature will ruin the bearings.
Can I use ducting with the ceiling extract fans models CEH 200/250?
No - these are "free air" fans. Any ducting will cause the fan to burn out
Can I use standard fans to draw out smoke from a chimney?
No - The maximum temperature the fan can handle is 60°C.
Can the fans "suck and blow"?
Certain domestic fans may be made to operate in reverse with the aid of a special controller.
This does produce less air. Generally, most fans are made to either work as "suckers" OR "blowers".
Do the CEH 200/250 have ball bearing or bushes?
Both models have bearings which are greased for life.
