Blauberg CALM100T Extractor Fan Kit with White Grille | CALM100TKITWH

Ultra-Quiet 100mm Zone 1 Timer Bathroom Extractor Fan Kit with 5m Insulated Ducting & White External Grille

The Blauberg CALM100T Extractor Fan Kit with White Grille | CALM100TKITWH is a complete ventilation package designed for bathrooms, shower rooms, en-suites, toilets and other moisture-prone areas where quiet and effective extraction is required.

At the heart of the kit is the Blauberg CALM 100 T, a 100mm timer extractor fan delivering up to 97m³/h (27 l/s) airflow while operating at just 25dBA. It features an adjustable 2–30 minute automatic run-on timer, anti-vibration motor mounting and an integrated backdraft shutter for efficient, low-noise moisture control.

The fan's IP45 rating also makes it suitable for appropriate Zone 1 bathroom installations when correctly installed in accordance with current electrical regulations.

The kit also includes 5 metres of 100mm SonoFlex insulated flexible ducting with 25mm Rockwool insulation, helping reduce heat loss, condensation risk and duct-borne noise where ventilation runs pass through cold lofts, roof voids and ceiling spaces.

Completing the installation is a 100mm white fixed-blade external ventilation grille, providing a clean, discreet termination that coordinates particularly well with white soffits, fascias, render and other light-coloured exterior finishes.

Complete Bathroom Ventilation Kit

The CALM100TKITWH combines the main components required for a typical 100mm bathroom extract installation into one convenient package.

Rather than purchasing the fan, insulated ducting and external termination separately, the kit combines the CALM 100 T timer extractor fan, 5m SonoFlex insulated flexible ducting and a white external ventilation grille matched around a 100mm ventilation system.

This makes it an excellent option for bathroom refurbishments, extensions, loft conversions and new ventilation installations where extracted air needs to be ducted to an exterior wall or soffit.

Ultra-Quiet CALM 100 T Extractor Fan

The Blauberg CALM 100 T has been engineered specifically for low-noise domestic ventilation.

Despite delivering an impressive 97m³/h (27 l/s) airflow, the fan operates at just 25dBA, helping provide effective extraction without the intrusive noise associated with many conventional bathroom fans.

Special anti-vibration motor mounts help minimise the transmission of motor vibration through the casing and surrounding structure.

The result is a quiet ventilation solution ideally suited to bathrooms, en-suites, toilets and other areas where low operating noise is important.

Adjustable 2–30 Minute Run-On Timer

The CALM 100 T incorporates an automatic adjustable run-on timer.

Once triggered, the fan can continue extracting after the switched input has been turned off, with the overrun period internally adjustable between approximately 2 and 30 minutes.

This is particularly useful in bathrooms and shower rooms because moisture remains in the air long after the occupant has left the room.

Rather than stopping extraction immediately when the light is switched off, the fan continues operating for the selected period to help remove residual humidity.

Effective Condensation & Moisture Control

Bathrooms, shower rooms and wet rooms can quickly accumulate large quantities of water vapour.

If this humid air is not adequately removed, moisture can condense on windows, mirrors, tiles, ceilings and other cooler surfaces.

With a maximum extraction rate of 97m³/h, the CALM 100 T helps remove moisture-laden air and improve ventilation.

Effective extraction can help reduce excessive condensation and the conditions that encourage damp and mould growth, while supporting better indoor air quality.

IP45 Rated for Bathroom Installation

The CALM 100 T carries an IP45 ingress-protection rating, providing protection appropriate for specified bathroom applications.

Its high IP rating allows the fan to be used in suitable Zone 1 and Zone 2 installations, subject to correct positioning, electrical protection and installation in accordance with the current edition of BS 7671 and applicable bathroom electrical requirements.

This can remove the need for a separate 12V SELV fan in installations where a suitably rated mains-powered fan is permitted.

All electrical installation work should be carried out by a suitably qualified person.

Integrated Anti-Backdraft Shutter

The CALM incorporates an anti-backdraft shutter to help reduce unwanted reverse airflow through the ventilation duct while the fan is switched off.

This can help minimise cold draughts and external air entering the room through the extract route.

The integrated design also reduces the need to add a separate internal backdraught shutter to many conventional installations.

A+ Energy-Efficient Ventilation

The Blauberg CALM combines strong extraction performance with low electrical consumption, achieving an A+ energy-efficiency rating.

This makes it a practical option for modern domestic ventilation projects where both effective moisture removal and ongoing energy consumption are important considerations.

5m SonoFlex Insulated Flexible Ducting

Included with the CALM100TKITWH is 5 metres of Blauberg SonoFlex 100mm insulated flexible ducting.

SonoFlex combines a flexible internal ventilation duct with 25mm Rockwool insulation, helping provide both thermal and acoustic insulation along the duct route.

It is particularly useful where bathroom ventilation ductwork needs to pass through:

• Cold Lofts
• Roof Voids
• Ceiling Voids
• Garages
• Unheated Areas
• Other Cold Building Spaces

Helps Reduce Condensation in Ductwork

Warm bathroom air can contain significant amounts of moisture.

When that warm air travels through uninsulated ducting in a cold loft or roof void, its temperature can fall rapidly, increasing the risk of water vapour condensing inside the duct.

The 25mm Rockwool insulation surrounding the SonoFlex duct helps reduce heat loss and the rate at which extracted air cools.

This makes insulated ducting particularly beneficial for longer ceiling-mounted bathroom extraction routes through cold spaces.

Thermal & Acoustic Insulation

SonoFlex also provides acoustic benefits.

Its insulated construction can help soften fan and airflow noise travelling through the ventilation system, complementing the already low 25dBA operating noise of the CALM 100 T.

This makes the kit particularly attractive where quiet ventilation is a priority.

White Fixed-Blade External Grille

The CALM100TKITWH is supplied with a 100mm white external ventilation grille, replacing the slate grey grille supplied with the CALM100TKITSG version.

Its fixed-blade louvred design provides a neat termination point for the ventilation duct while helping protect the opening from weather and debris.

The white finish is particularly well suited to:

• White Soffits
• White Fascias
• Light-Coloured Render
• White PVC Cladding
• Conservatories
• Modern Domestic Exteriors
• Traditional Properties

The result is a clean, unobtrusive exterior finish that coordinates naturally with many residential properties.

Wall or Ceiling Installation

The CALM fan is suitable for use in wall or ceiling-mounted ventilation arrangements, providing flexibility when planning the extract route.

For ceiling-mounted applications, the included 5m insulated duct is particularly useful for routing extracted air through a loft or ceiling void to an appropriate external termination.

For best performance, flexible ducting should generally be installed as short and straight as practical, avoiding unnecessary bends and compression that can increase airflow resistance.

Why Choose the Blauberg CALM100TKITWH?

The Blauberg CALM100TKITWH provides a convenient complete ventilation solution rather than simply supplying the extractor fan on its own.

The CALM 100 T combines powerful 97m³/h extraction with ultra-quiet 25dBA operation, while its adjustable 2–30 minute timer allows extraction to continue after the bathroom has been vacated.

Its IP45 rating, anti-backdraft shutter and energy-efficient design make it well suited to modern bathroom ventilation, while the included 5m SonoFlex insulated ducting provides additional thermal and acoustic protection where the duct route passes through a cold loft, ceiling void or roof space.

The kit is completed by a 100mm white external grille, providing a smart, discreet exterior termination that blends particularly well with white soffits, fascias and other light-coloured exterior finishes.

For installers and homeowners looking for a quiet 100mm timer bathroom extractor fan with insulated ducting and a white external grille, the CALM100TKITWH provides all three principal components in one convenient package.
