Blauberg CALM100T Extractor Fan Kit with Slate Grey Grille | CALM100TKITSG

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

The Blauberg CALM100T Extractor Fan Kit with Slate Grey Grille | CALM100TKITSG is a complete ventilation package designed for bathrooms, shower rooms, en-suites, toilets and other moisture-prone areas where quiet, 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 includes an adjustable 2–30 minute run-on timer, anti-vibration motor mounting and an integrated backdraft shutter for efficient, low-noise moisture control. Blauberg also rates the fan IP45, making it suitable for appropriate Zone 1 bathroom installations when installed in accordance with current wiring 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 slate grey fixed-blade external grille, giving the outside termination a neat contemporary appearance while helping protect the duct opening from rain, debris and insects.

Complete Bathroom Ventilation Kit

The CALM100TKITSG combines the key components required for a typical 100mm extract installation into one convenient package.

Rather than purchasing the fan, insulated ducting and exterior terminal separately, the kit combines the CALM 100 T timer fan, SonoFlex insulated flexible ducting and a slate grey external grille matched around a 100mm ventilation system.

This makes it particularly suitable for bathroom refurbishments, extensions, loft conversions and new ventilation installations where a duct route needs to pass from the room to an exterior wall or soffit.

Ultra-Quiet CALM 100 T Extractor Fan

The Blauberg CALM 100 T has been engineered for low-noise operation, producing just 25dBA while delivering up to 97m³/h (27 l/s) airflow. Blauberg uses anti-vibration motor mounts to minimise transmission of motor vibration into the fan casing and surrounding structure.

This combination of strong airflow and low operating noise makes it well suited to bathrooms, en-suites and other spaces where loud extractor noise can be intrusive.

Adjustable 2–30 Minute Run-On Timer

The integrated timer allows the fan to continue extracting after its switched input has been turned off.

The run-on period can be adjusted internally between 2 and 30 minutes, allowing ventilation to continue after a shower or bath when residual humidity is still present.

This helps remove lingering moist air rather than stopping ventilation immediately when the room light is switched off.

Effective Condensation & Moisture Control

Bathrooms and wet rooms can quickly accumulate moisture from showers, baths and other hot-water use.

With an extraction rate of 97m³/h, the CALM 100 T helps remove humid air before it condenses excessively on windows, tiles and other cold surfaces.

Effective ventilation can form an important part of controlling the conditions that encourage condensation, damp and mould growth.

IP45 Rated for Bathroom Installation

The CALM 100 T is IP45 rated and is marketed by Blauberg as suitable for Zone 1 and Zone 2 bathroom applications, subject to correct electrical installation.

This allows the fan to be used in locations where a standard lower-IP mains extractor may not be appropriate.

Bathroom electrical installations should always comply with the current edition of BS 7671 and any applicable RCD and zoning requirements.

Integrated Anti-Backdraft Shutter

An integrated backdraft shutter helps reduce unwanted reverse airflow through the ventilation opening while the fan is not operating.

This helps limit draughts and external air entering through the duct route, while also avoiding the need for a separate internal backdraught shutter in many standard installations.

5m SonoFlex Insulated Flexible Ducting

The kit includes 5 metres of Blauberg SonoFlex 100mm insulated flexible ducting, providing a practical duct route where the fan is not mounted directly through an external wall.

SonoFlex combines a flexible inner duct with 25mm Rockwool insulation and a protective aluminium laminate outer jacket.

It is particularly useful for duct routes passing through:

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

Helps Reduce Condensation in Ductwork

Warm, moisture-laden bathroom air can cool rapidly when it passes through ducting installed in a cold loft or roof space.

The 25mm Rockwool insulation surrounding SonoFlex helps slow this temperature change, reducing the conditions that can encourage condensation inside or around the ductwork.

This makes insulated ducting a valuable upgrade over standard uninsulated flexible hose for longer bathroom extract runs through cold areas.

Thermal & Acoustic Insulation

SonoFlex not only helps manage condensation but also provides useful thermal and acoustic properties.

Blauberg specifies a thermal conductivity of ≤0.04 W/mK, while the insulated construction also helps soften fan and airflow noise travelling along the duct route.

This complements the already low-noise CALM fan and helps create a quieter overall ventilation installation.

Slate Grey External Grille

The kit is finished externally with a 100mm Blauberg slate grey fixed-blade louvred grille.

Its contemporary slate grey finish is especially suited to modern windows, doors, guttering, soffits and external finishes where conventional bright white ventilation grilles may look out of place.

Blauberg's 100mm slate grey grille is designed as a termination for extractor fans and duct systems and incorporates a fixed louvre arrangement to maintain airflow while helping protect the opening from weather and debris.

Integrated Insect Mesh

The slate grey exterior grille also incorporates an insect and fly mesh, helping prevent insects and larger debris from entering the duct route.

Its removable core also simplifies installation and subsequent cleaning or maintenance.

Suitable for Wall or Ceiling Installation

The CALM fan can be incorporated into either wall or ceiling-mounted ventilation arrangements, giving installers flexibility in how the extract route is configured.

For ceiling installations, the included insulated ducting is particularly useful for routing extracted air through a loft or ceiling void to a suitable external terminal.

Flexible ducting should be kept as short, straight and fully extended as practical to minimise airflow resistance.
