1 / 3Manrose ID100T 100 mm Inline Shower Extractor Fan, 85 m³/h
The Manrose ID100T is a loft-mounted 100 mm inline extractor fan with an adjustable overrun timer and a stated airflow of 85 m³/h. Its remote installation suits bathrooms, shower rooms and toilets, but the listing describes a fan-only product, so ducting and grilles need to be sourced separately.

Pros and cons
Pros
- Timer overrun can continue extracting after the room light or fan switch is turned off.
- Remote mounting makes the fan unit suitable for installations where a ceiling-void or loft position is available.
- The stated 100 mm spigots match standard 100 mm ducting.
Cons
- Ducting and grilles are sold separately, so this is not a complete ventilation kit.

What to know before buying
Listing details to confirm
The listing has inconsistent airflow wording: it gives 85 m³/h and 23 litres per second in the feature text, but the description says 85 m/hr and 2 litres per second. The supplied voltage and 3-pin connector details are also not reconciled with the installation instructions, so confirm electrical requirements and the intended airflow before purchase. The title says fan unit only while the box list claims a fan with timer and bracket. The listing also recommends a 3A fused double-pole isolator and an electrician for fitting.
Who is it for?
A good fit for
- Buyers replacing an existing inline fan who can confirm that 100 mm ducting and the electrical arrangement suit their installation.
- Bathrooms, shower rooms or toilets where a remote fan position and adjustable post-switch-off running time are useful.
Less suited to
- Buyers needing an all-in-one kit with ducting and grilles included.
- Installations where the supplied electrical specification or stated extraction rate cannot be confirmed as suitable.

Customer feedback reports that the fan is quiet and easy to install, with positive comments about functionality, fit and replacement use. That may matter when replacing a compatible existing unit, although the listing’s conflicting airflow figures and unresolved electrical details still warrant checking for the intended installation. Some ratings are low, so experiences are not uniformly positive.
