Overview

Ultra-thin exhaust fans with a 100 mm deep body, for the case where the ceiling void is too shallow for a standard fan. The series covers 13B, 13B-L4, 13B-L6, 14B5, 15B-L and 15B, sharing a housing listed at 9" × 9" × 5-3/4", and a 10W dimmable LED panel at 3000K–5000K behind a glass panel on the versions that carry it.

These are retrofit fans: the catalogue lists installation without cutting or attic access, and the units ship with hanger bars and foldable mounting ears. The shallow body is the reason the series exists — it goes into voids where a standard-depth fan will not. Airflow and sound are not published at family level, so selection starts from the housing depth and the light option, then is confirmed against the ventilation rate the room needs.

Where it is used

Bathroom exhaust in a retrofit with a shallow ceiling void
Ensuite and powder room ventilation in multi-unit residential
Bedroom or hallway exhaust where the fan also provides the room light
Mid-rise and multi-family projects where ceiling depth is restricted
Light-commercial washrooms

Selection & installation notes

01
Check the ceiling void first: the body is 100 mm deep and the housing is listed at 9" × 9" × 5-3/4". Measure the void and the joist spacing before ordering.
02
Confirm the light option for the series you order. The listed LED is 10W dimmable, 3000K–5000K, with a glass panel; check dimmer compatibility before it goes on the schedule.
03
Airflow, static pressure, duct size, sound level and power supply are not published at family level — confirm per model on the submittal sheet.
04
The listed working temperature is −10°C to 40°C, so this is an indoor, conditioned-space fan.
05
Hanger bars and foldable ears are supplied, which suits installation from below without attic access.

Common questions

Will it fit a shallow ceiling?

The body is 100 mm deep with a housing listed at 9" × 9" × 5-3/4". Measure the void and the joist spacing before ordering; if the space is tighter than that, ask us about the alternatives.

Is the LED dimmable, and at what colour temperature?

The listed LED is 10W dimmable, 3000K–5000K, behind a glass panel. Confirm the dimmer you intend to use with us before quoting.

What airflow does it deliver?

Airflow is not published at family level. Tell us the ventilation rate and the duct run and the factory will confirm the model and its data on the submittal sheet.
