Envirovent QRHT-LC Quro-LC Low Noise Decentralised Mechanical Extract Unit with Adjustable Timer & Humidity Sensor
Product Overview
The Envirovent QRHT-LC Quro-LC is a SAP PCDB listed decentralised mechanical extract ventilation (dMEV) unit designed for low noise, high efficiency and complete flexibility. Suitable for kitchens, bathrooms, en-suites, utility rooms and WCs, it provides reliable continuous extraction in both through-wall and ducted installations.
Delivering sound levels of below 9 dB(A) at 3 metres and a maximum airflow of 30 l/s (108m³/hr), the Quro-LC ensures powerful performance with minimal disruption. With a market-leading Specific Fan Power (SFP) of down to 0.08 W/l/s, it offers excellent energy efficiency and supports SAP compliance requirements.
Advanced Performance with Back Pressure Detection
Aerodynamically engineered with integrated back pressure detection, the QRHT-LC automatically compensates for external resistance and varying installation conditions. Two selectable installation configurations allow accurate commissioning, ensuring required airflow rates are achieved while maintaining compliance with regulations.

- SAP PCDB listed with SFP down to 0.08 W/l/s
- Ultra-quiet operation below 9 dB(A) at 3m
- Low energy DC motor for improved efficiency
- Back pressure detection menu for precise setup
- 3 year manufacturer warranty
Intelligent Timer & Humidity Control
The QRHT-LC model features an automatic intelligent over-run timer that adjusts operation based on how long the fan has been running in boost mode. This ensures optimal moisture extraction without unnecessary energy consumption.
An integrated intelligent humidity sensor monitors relative humidity levels and automatically adjusts fan speed when required. This proactive control helps reduce condensation, damp and mould growth while maintaining a healthy indoor environment.
User-Friendly Digital Display
A side-mounted digital interface provides intuitive control over fan speed, timer settings, humidity parameters (model dependent) and installation type selection (through-wall or ducted). The display also shows runtime information, current humidity levels (where applicable) and diagnostic error codes.
Flexible Commissioning with Multiple Speeds
The Quro-LC offers multiple selectable trickle speeds ranging from 5 l/s to 19 l/s, factory set at 8 l/s, allowing precise adjustment to suit property requirements. Boost speeds are selectable between 20 and 28 l/s, factory set at 25 l/s, with settings based on installation configuration.
This flexibility makes the QRHT-LC suitable for a wide range of domestic applications, delivering consistent ventilation performance regardless of property exposure or duct layout.
Low Maintenance Design
Designed for hassle-free servicing, the Quro-LC does not require filters. The front cover can be easily removed for cleaning with a dry cloth, reducing maintenance time and ongoing costs.
