A 100mm Newlec extractor fan, with timer, was fitted into my (plasterboard) cloakroom ceiling about 7 years ago and despite light use, it's recently packed up. I've never been impressed with this device so I'm looking for a higher quality replacement that has a chance of lasting 10+ years.
I dug out the installation & wiring instructions for the fan and the brand name, Newlec, doesn't appear anywhere in the manual although model numbers are mentioned that are similar (though not identical) to Newlec extractor fans currently on the market. Seems my failed fan is the model NLLPF100TA. I guess this is a cheap generic product which carries various sellers' branding?
Anyway, this fan has always been better at making noise than shifting air. Specified at 21 L/sec air flowrate, I doubt it's half that though that may be due to generating such little pressure that it struggled to push open the external plastic louvre shutter sited on an external wall. Maybe the fan has an in-built backdraft valve and having to push through two such arrangements proved too much? I'll find out when I replace it. The fan is connected to approx. 1.2m corrugated 100mm plastic trunking that forms a very gentle 90 deg curve over it's entire length. I've checked the trunking and it's in good condition.
Do all these 100mm axial fans struggle to open anti-backdraft louvred flaps? In use, I had to set the maximum timer duration of approx. 30 mins so it adequately cleared a 4.8 cubic metre cloakroom.
I'm in two minds. I could simply buy a higher quality replacement. Is this a good option?
or go for a inline fan, axial or centrifugal, mounted in the loft? Something like this (although one with more airflow and power usage data):
Interested to hear thoughts, many thanks.
