Blauberg CALM100T Extractor Fan Kit with Brown Grille | CALM100TKITBR

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

The Blauberg CALM100T Extractor Fan Kit with Brown Grille | CALM100TKITBR is a complete bathroom ventilation package combining quiet, powerful extraction with insulated ducting and a smart brown exterior termination.

At the heart of the kit is the Blauberg CALM 100 T, a 100mm timer extractor fan capable of 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 anti-backdraft shutter. The fan is also rated IP45 and is suitable for appropriate Zone 1 bathroom installations when correctly installed.

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 brown fixed-blade external ventilation grille, providing a discreet exterior finish particularly suited to brickwork, timber, brown fascias and darker exterior finishes. Blauberg confirms its brown 100mm grille has a 100mm duct connection, weather-resistant fixed louvres and an integrated insect/fly mesh.

Complete Bathroom Ventilation Kit

The CALM100TKITWBR combines the main components required for a typical 100mm bathroom extraction system into one convenient package.

Instead of purchasing the fan, insulated ducting and exterior grille individually, this kit combines the CALM 100 T timer extractor fan, 5m SonoFlex insulated flexible ducting and a brown 100mm external ventilation grille.

It's an excellent option for bathroom refurbishments, extensions, loft conversions and new installations where extracted air needs to travel through a loft, ceiling void or other space before terminating outside.

Ultra-Quiet CALM 100 T Extractor Fan

The Blauberg CALM 100 T has been engineered to provide powerful bathroom extraction without excessive operating noise.

Despite delivering up to 97m³/h (27 l/s) airflow, the fan operates at only 25dBA. Special anti-vibration mounting helps isolate motor vibration from the fan casing and surrounding structure, contributing to its low-noise performance.

This makes the CALM particularly well suited to en-suites, bathrooms and other areas where extractor-fan noise can be intrusive.

Adjustable 2–30 Minute Run-On Timer

The CALM 100 T incorporates an automatic run-on timer adjustable between approximately 2 and 30 minutes.

Once the switched input is turned off, the fan can continue extracting for the selected period. This is particularly useful after showers and baths because significant moisture can remain in the room after the occupant has left.

Continued extraction helps remove this residual humid air rather than stopping ventilation immediately when the room light is switched off.

Powerful 97m³/h Moisture Extraction

With an extraction capacity of 97m³/h, equivalent to 27 litres per second, the CALM 100 T provides effective airflow for domestic bathrooms, shower rooms, wet rooms and toilets.

Efficient extraction helps remove moisture-laden and stale air, reducing excessive condensation on windows, mirrors, walls and other cooler surfaces.

By controlling excess humidity, effective ventilation can also help reduce the conditions that encourage damp and mould growth.

IP45 Rated for Bathroom Installation

The CALM 100 T has an IP45 ingress-protection rating, and Blauberg markets the fan as suitable for appropriate Zone 1 and Zone 2 bathroom applications.

This makes it a versatile alternative to conventional lower-IP bathroom extractor fans.

Final positioning and electrical installation must comply with current BS 7671 requirements, including appropriate RCD protection and bathroom zoning requirements.

Integrated Anti-Backdraft Shutter

An integrated anti-backdraft shutter helps prevent unwanted reverse airflow through the ventilation route while the fan is switched off.

This helps minimise draughts and unwanted external air entering the bathroom through the ductwork.

Combined with the external grille, it provides a practical ventilation arrangement without requiring a separate internal backdraught shutter in many installations.

A+ Energy-Efficient Ventilation

The Blauberg CALM combines strong airflow with low electrical consumption.

Blauberg specifies the CALM 100 T at just 7.5W, alongside an A+ energy-efficiency rating.

This makes it a particularly attractive choice for modern bathroom ventilation projects where both performance and energy consumption are important.

5m SonoFlex Insulated Flexible Ducting

Included with the CALM100TKITBR is 5 metres of 100mm SonoFlex insulated flexible ducting.

Its insulated construction uses 25mm Rockwool insulation, providing both thermal and acoustic benefits compared with conventional uninsulated flexible ducting.

It's particularly useful for ventilation routes passing through:

• Cold Lofts
• Roof Voids
• Ceiling Voids
• Garages
• Unheated Building Spaces
• Loft Conversions

Helps Reduce Duct Condensation

Warm bathroom air can carry substantial amounts of moisture.

When that air passes through uninsulated ductwork located in a cold loft or roof space, its temperature can fall rapidly, increasing the potential for condensation within the duct.

The 25mm insulation surrounding the SonoFlex ducting helps reduce heat loss from the extracted air, making insulated ducting a particularly useful choice for longer ventilation routes through cold spaces.

Thermal & Acoustic Insulation

The insulated ducting also helps reduce the transmission of fan and airflow noise through the ventilation system.

Combined with the CALM 100 T's low 25dBA operating noise, this makes the kit well suited to installations where acoustic comfort is a priority.

For best airflow performance, flexible ducting should be installed as straight and fully extended as practical, avoiding unnecessary bends and compression.

Brown Fixed-Blade External Grille

The key difference with the CALM100TKITBR is its brown 100mm external grille.

Blauberg's round brown external grille is designed for a 100mm duct opening and features fixed louvres to maintain ventilation while helping protect the duct termination from rain and debris.

The brown finish is particularly suited to:

• Brown Brickwork
• Traditional Brick Properties
• Timber Cladding
• Brown Fascias
• Brown Soffits
• Dark Window Frames
• Traditional Residential Exteriors
• Darker Exterior Finishes

Blauberg specifically describes the finish as a rustic brown designed to complement building exteriors.

Integrated Insect & Fly Mesh

The brown external grille incorporates an insect and fly mesh, helping prevent insects and larger debris from entering the ventilation duct.

The grille also has a detachable core to simplify installation, cleaning and ongoing maintenance.

Wall or Ceiling Installation

The CALM fan can be incorporated into either wall or ceiling-mounted ventilation installations.

For ceiling-mounted installations, the included 5m insulated duct is particularly useful for routing extracted bathroom air through a loft or roof space before terminating through an external wall or soffit.

This provides greater installation flexibility than a basic through-the-wall fan arrangement.
