Continuous Running and Intermittent Ventilation

The EnviroVent ECO-DMEV-S-LC is designed to provide flexible ventilation operation.

The fan can be configured for continuous background extraction or intermittent operation, depending on the application and installation requirements.

Continuous Running Operation

In continuous mode, the fan operates at a selected low-level extraction rate throughout the day.

This provides ongoing ventilation to help remove everyday moisture, stale air and unwanted odours.

When additional extraction is required, the fan can be boosted through a suitable external switch.

Benefits of Continuous Ventilation

• Provides ongoing background extraction
• Helps manage everyday moisture
• Supports improved indoor air quality
• Reduces the accumulation of stale air
• Suitable for modern domestic ventilation systems
• Low-energy operation for extended running periods
• Practical for bathrooms, kitchens and utility rooms

Intermittent Operation

The fan can also operate intermittently in suitable applications.

This allows extraction to be activated when required rather than running continuously.

Important: The manufacturer states that intermittent operation is not suitable for kitchen and utility room applications. These locations require an appropriate continuous ventilation configuration.

Adjustable Background Airflow

The EnviroVent ECO dMEV LC features adjustable background airflow settings.

This allows the installer to configure the fan's extraction rate according to the requirements of the room.

The manufacturer's technical information identifies adjustable trickle settings ranging from approximately 4–13L/s, with boost extraction up to approximately 17L/s.

Benefits of Adjustable Airflow

• Allows extraction rates to be configured
• Suitable for different room requirements
• Supports effective background ventilation
• Helps balance airflow and energy consumption
• Practical for continuous ventilation systems
• Provides flexibility during commissioning

Correct airflow settings are essential to ensure that the ventilation system meets the intended installation requirements.

External Switch Boost Function

The ECO-DMEV-S-LC is the standard model within the ECO dMEV LC range.

It can provide increased extraction when activated through an appropriate external switch.

This allows the fan to operate at a low background setting during normal conditions and increase ventilation when additional extraction is required.

Benefits of Boost Ventilation

• Provides increased extraction when needed
• Useful during bathroom use
• Helps remove excess moisture
• Supports improved ventilation during periods of higher humidity
• Practical for domestic ventilation systems
• Allows control through a suitable external switch

Unlike the timer and humidistat models, the standard ECO-DMEV-S-LC does not incorporate automatic timer or humidity-responsive controls.

Energy-Efficient Low-Wattage DC Motor

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

The manufacturer's technical information specifies an absorbed power range of approximately 0.8W to 5.6W, depending on the selected operating setting.

This makes the fan particularly suitable for continuous ventilation applications.

Benefits of DC Motor Technology

• Low electricity consumption
• Suitable for continuous background extraction
• Efficient airflow performance
• Helps minimise running costs
• Practical for energy-conscious homes
• Suitable for new-build and refurbishment projects
• Designed for reliable everyday operation

The motor is mounted on vibration-reducing supports and incorporates sealed-for-life ball bearings to support quiet operation and long-term performance.

Actual electricity consumption depends on the selected airflow setting and installation conditions.

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.

These figures are based on the manufacturer's stated measurement conditions.

Benefits of Quiet Ventilation

• Suitable for bathrooms and en-suites
• Helps minimise 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

The fan's low-noise design makes it particularly useful for properties where ventilation may operate for extended periods.

Please note: Actual noise levels depend on airflow settings, ductwork, mounting arrangements and surrounding conditions.

Centrifugal Extraction Technology

The EnviroVent ECO-DMEV-S-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 provides adjustable airflow settings, allowing ventilation performance 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
• Adjustable trickle settings: Approximately 4–13L/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 ductwork design, installation resistance and selected settings.

Ideal for Bathroom Ventilation

The EnviroVent ECO dMEV LC 100mm Extractor Fan is particularly suitable for bathroom ventilation.

Bathrooms frequently experience increased humidity due to showers, baths and everyday use.

Without adequate ventilation, moisture can accumulate on walls, ceilings, windows and other surfaces.

The ECO-DMEV-S-LC helps extract humid air, supporting improved indoor air quality and reducing conditions that can contribute to condensation.

Bathroom Ventilation Benefits

• Helps remove excess moisture
• Supports condensation control
• Extracts stale air and unwanted odours
• Suitable for continuous background ventilation
