Blauberg CALM100T Extractor Fan Kit with Terracotta Grille | CALM100TKITTC

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

The Blauberg CALM100T Extractor Fan Kit with Terracotta Grille | CALM100TKITTC is a complete bathroom ventilation package combining powerful, ultra-quiet extraction with insulated ducting and a stylish terracotta 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 IP45 rated and suitable for appropriate Zone 1 bathroom installations when correctly installed.

The kit also includes 5 metres of 100mm SonoFlex insulated flexible ducting, providing thermal and acoustic insulation for ventilation routes through lofts, roof voids and other unheated spaces.

Completing the installation is a genuine Blauberg 100mm terracotta fixed-blade external grille. Its warm terracotta finish is particularly well suited to red and orange brickwork, clay tiles and traditional building exteriors. Blauberg confirms the grille is weather resistant, incorporates an insect/fly mesh and is designed for 100mm ventilation systems.

Complete Bathroom Ventilation Kit

The CALM100TKITTC brings together the principal components required for a typical 100mm bathroom extraction installation.

Rather than purchasing the extractor fan, insulated ducting and exterior termination separately, this kit combines the CALM 100 T timer fan, 5m SonoFlex insulated ducting and a terracotta 100mm external ventilation grille.

This makes it ideal for bathroom refurbishments, extensions, loft conversions and new installations where moist air needs to be ducted through a ceiling void, loft or other space before being discharged externally.

Ultra-Quiet CALM 100 T Extractor Fan

The Blauberg CALM 100 T has been engineered to deliver effective bathroom ventilation without excessive operating noise.

It provides up to 97m³/h (27 l/s) airflow while producing a sound level of only 25dBA. Special anti-vibration mounting helps isolate motor vibration from the fan casing and surrounding structure.

This makes the CALM particularly well suited to en-suites, bathrooms, toilets and other spaces 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 from approximately 2 to 30 minutes.

Once the switched input has been turned off, the fan continues extracting for the selected period. This is particularly useful following a shower or bath, when significant moisture can remain in the room after it has been vacated.

Continued extraction helps remove this residual humidity rather than stopping ventilation as soon as 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 ventilation for bathrooms, shower rooms, wet rooms and toilets.

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

By controlling excess humidity, effective ventilation can also help reduce the conditions that encourage damp and mould growth while contributing to better indoor air quality.

IP45 Rated for Bathroom Installation

The CALM 100 T has an IP45 ingress-protection rating and is marketed by Blauberg for appropriate Zone 1 and Zone 2 bathroom installations.

This provides greater installation flexibility than conventional lower-IP mains-powered bathroom fans.

Final positioning and electrical installation must comply with the current edition of BS 7671 and applicable bathroom-zone and RCD requirements. Electrical work should be undertaken by a suitably qualified person.

Integrated Anti-Backdraft Shutter

An integrated anti-backdraft shutter helps minimise unwanted reverse airflow through the ventilation duct when the fan is switched off.

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

The integrated shutter also means a separate internal backdraught shutter may not be required in many standard installations.

A+ Low-Energy Ventilation

Despite its strong airflow performance, the CALM 100 T consumes only 7.5W and carries an A+ energy rating.

This combination of high airflow and low power consumption makes it a practical choice for modern domestic ventilation installations where energy efficiency and effective moisture extraction are both priorities.

5m SonoFlex Insulated Flexible Ducting

Included with the CALM100TKITTC is 5 metres of 100mm SonoFlex insulated flexible ducting.

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

It is 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 significant amounts of water vapour.

When that air travels through uninsulated ducting in a cold loft or roof space, it can cool rapidly, increasing the likelihood of condensation forming within the ventilation system.

The insulation surrounding the SonoFlex duct helps limit heat loss from the extracted air and therefore helps reduce condensation risk within cold duct runs.

This makes insulated ducting especially useful for ceiling-mounted extractor fans where the duct passes through an unheated loft before reaching the exterior.

Thermal & Acoustic Insulation

SonoFlex ducting also provides useful acoustic properties.

Its insulated construction helps soften fan and airflow noise travelling along the ventilation route, complementing the CALM 100 T's already low 25dBA operating noise.

For optimum airflow, flexible ducting should be installed as straight and fully extended as practical, with unnecessary bends and compression kept to a minimum.

Terracotta Fixed-Blade External Grille

The defining feature of the CALM100TKITTC is its 100mm terracotta external ventilation grille.

Blauberg's DECOR 100-MB TERRACOTTA grille is specifically designed for 100mm ventilation systems and provides a neat termination point for extractor fans and ventilation ducting.

Its fixed louvres help maintain airflow while providing protection against rain and debris, and the grille's terracotta finish is designed to coordinate attractively with traditional exterior materials.

Ideal for Brick & Terracotta Exterior Finishes

The terracotta grille provides a warmer and more sympathetic exterior appearance than a standard white ventilation grille.

It is particularly well suited to:

• Red Brick Properties
• Orange & Terracotta Brickwork
• Clay Roof Tiles
• Terracotta Exterior Finishes
• Traditional Residential Properties
• Period-Style Buildings
• Warm-Coloured Render
• Matching Exterior Fixtures

This allows the external termination to blend more naturally into the building rather than standing out as a contrasting white fitting.

Integrated Insect & Fly Mesh

Blauberg's terracotta external grille incorporates an integrated insect and fly mesh, helping prevent insects and larger debris from entering the ventilation system.

The grille also incorporates a detachable core, helping simplify installation and ongoing cleaning.

Weather-Resistant External Termination

The grille is manufactured for exterior ventilation applications and is designed to withstand exposure to adverse weather while helping protect the duct opening against rain and debris.

It can be used as an external termination for extractor fans and ventilation ductwork, including appropriate wall, soffit and fascia installations.

Wall or Ceiling Installation

The CALM fan can be incorporated into either wall or ceiling-mounted ventilation installations, providing flexibility when planning the extract route.

For ceiling-mounted installations, the included 5m insulated ducting is particularly useful for routing moist bathroom air through a loft or roof space before terminating at an appropriate external location.
