Continuous Constant Volume Ventilation
The Vent-Axia Response 7 Pro uses decentralised mechanical extract ventilation (dMEV) technology to provide continuous background extraction, helping remove excess moisture, stale air and household odours.
The Pro model incorporates constant volume airflow control, designed to maintain the commissioned extraction rate as installation conditions change. This helps deliver reliable ventilation performance and supports consistent indoor air quality.
With extraction rates of up to 35 l/s, the fan is suitable for a range of domestic applications, including bathrooms, kitchens, toilets and utility rooms.
Smart Sense™ Intelligent Technology
The integrated Smart Sense™ system makes the Vent-Axia Lo-Carbon Response 7 Pro straightforward to install, configure and monitor.
A clear alphanumeric LED display and three-button menu provide easy access to commissioning settings and operational information. The display automatically adjusts its orientation according to whether the fan is installed on a wall or ceiling, improving accessibility during installation.
Smart Sense™ technology provides useful performance information, including:
- Total number of days the fan has been operating.
- Running hours in continuous trickle mode.
- Total operating hours in boost mode.
- Boost running hours triggered by humidity control, where applicable.
- Recorded energy consumption.
- Installed airflow and system pressure information.
This detailed operational monitoring is particularly valuable for landlords and housing associations managing ventilation performance across multiple properties.
Digital Airflow and System Pressure Monitoring
The Response 7 Pro features an innovative digital display that provides information about installed airflow and system pressure.
This allows installers to check ventilation performance during commissioning and helps property managers assess whether the fan is operating as intended.
The clear digital interface reduces the complexity of setup and supports accurate adjustment of ventilation settings.
High-Performance Trickle and Boost Ventilation
The Vent-Axia 494144 is designed to provide effective continuous extraction at trickle speed, helping maintain good indoor air quality without frequent high-speed operation.
When additional extraction is required, boost operation increases airflow to help remove moisture and odours more quickly.
This combination of continuous background ventilation and responsive boost performance helps manage condensation while maintaining a quieter living environment.
Comfort Control Technology
The Lo-Carbon Response 7 range features an optional patented Comfort Control function designed to minimise unnecessary boost activation during short bathroom visits.
When selected during installation, the delayed-start function can postpone boost activation for up to 20 minutes, allowing occupants to use the bathroom without immediate increased fan noise.
If the bathroom light is switched on and off within three minutes, the boost function will not activate. This is particularly beneficial during night-time bathroom visits, helping reduce disturbance to other household members.
Designed for Social Housing and Residential Properties
The Vent-Axia Response 7 Pro has been developed with the needs of social housing providers, landlords and residents in mind.
Its filterless design reduces maintenance requirements, while the ultra-low-profile construction provides a discreet appearance in bathrooms and other domestic spaces.
The integrated settings lock helps prevent unauthorised adjustments, ensuring commissioned ventilation settings remain consistent. Smart Sense™ data logging also enables property managers to review operating information and demonstrate that the fan has been running.
Energy-Efficient and Low-Maintenance Operation
Featuring Vent-Axia's Lo-Carbon motor technology, the Response 7 Pro is designed to provide reliable continuous extraction with low energy consumption.
The fan's efficient background ventilation performance helps minimise unnecessary boost operation, while the filterless construction eliminates the need for routine filter replacement.
Its compact design and optional decorative frame support a clean, professional installation in both new and refurbished properties.
