EnviroVent ECO dMEV LC 100mm (4") Extractor Fan with Timer | ECO-DMEV-T-LC

Quiet, Energy-Efficient Continuous Running Extractor Fan for Bathrooms, Kitchens and Utility Rooms

The EnviroVent ECO dMEV LC 100mm (4") Extractor Fan with Timer is a high-performance, energy-efficient ventilation solution designed to improve indoor air quality by extracting moisture, stale air and unwanted odours from domestic environments.

Featuring a low-energy DC motor, adjustable overrun timer, centrifugal fan technology and IPX4 splash protection, the ECO-DMEV-T-LC offers reliable ventilation for bathrooms, toilets, kitchens and utility rooms.

Part of the EnviroVent ECO dMEV LC range, this compact extractor fan is designed for continuous or intermittent operation, depending on the installation requirements.

Its continuous running functionality provides background ventilation, while the boost function allows increased extraction when additional airflow is required.

The fan features an adjustable run-on timer, allowing ventilation to continue for a selected period after the boost activation signal is removed. This helps extract lingering moisture and odours after bathroom use.

With an airflow range of approximately 15–60m³/h (4–17 litres per second), the ECO dMEV LC provides flexible ventilation performance for suitable domestic applications.

The efficient DC motor consumes as little as 0.8W at minimum operation, with a maximum absorbed power of approximately 5.6W, helping to reduce electricity consumption compared with many conventional extractor fans.

Designed for quiet operation, the fan produces sound pressure levels below 20dB(A) at minimum operation, making it particularly suitable for bathrooms, en-suites and other areas where low-noise ventilation is desirable.

The 100mm (4-inch) duct connection makes it suitable for compatible ventilation ducting systems, while its compact construction allows installation in suitable wall, ceiling or panel locations.

With a contemporary white finish and interchangeable front panel trims, the ECO-DMEV-T-LC offers a discreet appearance that complements modern bathrooms and utility spaces.

The fan is also Class II double insulated and IPX4 rated, providing electrical protection suitable for appropriately designed installations in moisture-prone environments.

Backed by a 2-year manufacturer's warranty, the EnviroVent ECO-DMEV-T-LC is a practical choice for electricians, ventilation installers, property developers and homeowners seeking efficient, quiet and dependable extraction.

Continuous Running and Intermittent Ventilation

The EnviroVent ECO dMEV LC has been developed to offer flexible ventilation operation.

The fan can be configured for continuous background extraction or intermittent operation where permitted by the installation requirements.

Continuous Running Operation

In continuous mode, the fan provides low-level background ventilation throughout the day.

When additional extraction is required, the fan can operate at a higher airflow setting.

This makes continuous operation particularly useful for controlling everyday moisture and maintaining ventilation in domestic properties.

Benefits of Continuous Ventilation

• Provides ongoing background extraction
• Helps manage everyday moisture
• Supports improved indoor air quality
• Reduces the accumulation of stale air
• Useful for bathrooms and utility spaces
• Low-energy operation for extended running periods

Intermittent Operation

Intermittent operation allows the fan to operate when activated rather than providing continuous background extraction.

Important: The manufacturer identifies restrictions on intermittent operation for kitchen and utility room applications. For these locations, the fan should be configured and installed according to the manufacturer's instructions and applicable ventilation requirements.

Energy-Efficient Low-Wattage DC Motor

The ECO-DMEV-T-LC incorporates a low-energy DC motor designed to provide efficient extraction with minimal electricity consumption.

According to the manufacturer's technical information, the ECO dMEV LC range has an absorbed power range of approximately 0.8W to 5.6W, depending on the operating setting.

This makes the fan suitable for installations where energy efficiency is an important consideration.

Benefits of Low-Energy DC Technology

• Low electricity consumption
• Suitable for continuous ventilation
• Efficient extraction performance
• Reduced running costs compared with higher-wattage alternatives
• Practical for modern energy-conscious homes
• Suitable for new-build and refurbishment projects

The low-energy motor is particularly beneficial when the fan is configured for continuous background ventilation.

Actual energy consumption will depend on the selected airflow settings and operating conditions.

Ultra-Quiet Extractor Fan Operation

The EnviroVent ECO dMEV LC is designed to provide effective ventilation while maintaining low noise levels.

The manufacturer's technical data specifies sound pressure levels of below 20dB(A) at minimum operation, increasing to approximately 32dB(A) at maximum operation, measured at a distance of 3 metres under the stated test conditions.

This makes the fan an attractive choice for bathrooms, en-suites and other domestic spaces where quieter ventilation is desirable.

Benefits of Quiet Ventilation

• Suitable for bathrooms and en-suites
• Minimises noise during background operation
• Practical for bedrooms with adjoining bathrooms
• Comfortable for everyday domestic use
• Suitable for continuous ventilation
• Helps maintain a quieter indoor environment

Noise levels experienced after installation will depend on mounting arrangements, ductwork, airflow settings and surrounding conditions.

Powerful Centrifugal Extraction

The ECO-DMEV-T-LC uses a centrifugal fan design to provide effective extraction through suitable ductwork.

Centrifugal extractor fans are commonly selected for ventilation installations where airflow must be maintained against resistance from ducting and associated components.

The ECO dMEV LC range offers adjustable airflow settings, allowing the ventilation rate to be configured for the intended application.

Airflow Performance

• Minimum airflow: 15m³/h
• Maximum airflow: 60m³/h
• Minimum extraction rate: Approximately 4L/s
• Maximum extraction rate: Approximately 17L/s

Benefits of Centrifugal Extraction

• Suitable for ducted ventilation applications
• Adjustable airflow performance
• Practical for bathroom extraction
• Suitable for continuous background ventilation
• Helps remove moisture and stale air
• Useful for domestic ventilation systems

Actual installed airflow will depend on the ductwork design, installation resistance and selected settings.
