Combining great looks with excellent performance, the SP SILDES100HT 'Silent Design' is an exceptional extractor fan. Using an IPX5 rated motor, it is "resistant to jets of water from all angles" and can therefore be installed anywhere in the bathroom. Powerful and quiet, it is also very energy efficient, using only 8w..which is about the same as an LED lamp! The SILDES100HT features an integral humidistat, adjustable on install from 60 - 90% Relative Humidity. This humidistat option is particularly suited to tenanted properties, bathrooms with lots of natural light or indeed any situation in which their is a risk the fan will not be turned on manually.

You will need the following, all available from the accessories list below:
1 x Length of flexible aluminium ducting. (sold by the metre)

Stylish with quiet operation, humidistat was required and works well in the bathroom.

Good looking extractor with quiet operation.

Humidistat fans

Purchased two of these after a recommendation. Easy to install, very quiet unlike my last fan. Have found my bathroom & en-suite a lot drier which is great. You can change the timer & humidity on the fan which is great too. Very pleased, fab price too.

Looks good

Received quick, haven't finished wet room yet so still need to install but unpacked & all looks good.

Great Web site

Quiet and effective fan

The humidistat sensor works well at keeping our bathroom dry.

The motor runs very quietly so far.

The anti backdraft is just a thin plastic sheet that creates an annoying fluttering sound while the fan is running.
