Product Overview

The Envirovent QRST-LC Quro-LC is a SAP PCDB listed decentralised mechanical extract ventilation (dMEV) unit engineered for low noise operation, high efficiency and flexible installation. Suitable for kitchens, bathrooms, en-suites, utility rooms and WCs, it delivers continuous, reliable ventilation for modern homes.

Producing sound levels of below 9 dB(A) at 3 metres and offering a maximum airflow of 30 l/s (108m³/hr), the QRST-LC combines discreet performance with powerful extraction. With a market-leading Specific Fan Power (SFP) of down to 0.08 W/l/s, it supports SAP compliance and energy-efficient building standards.

Advanced Performance with Back Pressure Detection

The Quro-LC range has been aerodynamically designed with integrated back pressure detection to ensure required airflow rates are achieved in a variety of installation scenarios. Two selectable installation configurations (through-wall or ducted) allow precise commissioning while taking property exposure and external conditions into account.

• Maximum airflow up to 30 l/s (free air)
• 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 regulatory compliance
• 3 year manufacturer warranty

Automatic Intelligent Timer

The QRST-LC features an automatic intelligent over-run timer that adjusts the run-on period depending on how long the fan has been operating in boost mode. This ensures effective moisture extraction while optimising energy consumption.

User-Friendly Digital Controls

A side-mounted digital display provides intuitive control of fan speed, timer settings and installation type. The interface also displays runtime information, operational status and diagnostic error codes for straightforward setup and maintenance.

Flexible Set-Up with Multiple Fan Speeds

The Quro-LC offers multiple selectable trickle speeds ranging from 5 l/s to 19 l/s, factory set at 8 l/s, enabling accurate commissioning to suit individual property requirements.

Boost speeds are selectable between 20 and 28 l/s, factory set at 25 l/s, with settings based on the chosen installation configuration. The maximum airflow in free air is 30 l/s, ensuring strong performance across a range of applications.

Low Maintenance Design

Designed for fuss-free maintenance, the Quro-LC does not require filters. The removable front cover allows quick and simple cleaning with a dry cloth, reducing ongoing maintenance time and cost.
