Efficient dMEV Ventilation

Unlike a conventional intermittent extractor fan, the CALM 100 dMEV is designed for decentralised mechanical extract ventilation, providing an efficient approach to maintaining air quality and controlling moisture within suitable domestic applications.

Continuous low-energy extraction helps remove humid and stale air, reducing the risk of:

• Excess condensation
• High humidity
• Mould growth
• Damp-related problems
• Poor indoor air quality

Automatic Humidity Control

The integrated humidity sensor can be adjusted between 60% and 90% relative humidity (RH).

When humidity levels increase, such as during a shower or bath, the fan can respond automatically to provide increased extraction without requiring manual intervention.

This makes it particularly suitable for bathrooms and other rooms where humidity levels can change rapidly.

Adjustable Run-On Timer

The TH version also features an integrated turn-off delay timer, adjustable between 2 and 30 minutes.

This allows the fan to continue extracting moisture and stale air for a selected period after activation, helping ensure the room is thoroughly ventilated.

Ultra-Quiet Operation

Blauberg's specially designed mixed-flow impeller combines strong airflow performance with low operating noise.

With a sound pressure level of just 25dB(A), the CALM 100 dMEV is an excellent option for installations where quiet operation is a priority, including bathrooms located close to bedrooms and other living areas.

Ultra-Low Energy Consumption

With maximum power consumption of just 3.4W, the CALM dMEV is designed for efficient long-term operation.

An SFP of only 0.278 W/l/s helps keep electricity consumption low, making the fan particularly well suited to continuous domestic ventilation applications.

The Blauberg CALM dMEV range is designed to comply with key requirements of the UK Building Regulations, including:
