Product Overview

The Envirovent QRST Quro is a SAP PCDB listed decentralised mechanical extract ventilation (dMEV) unit designed to deliver continuous, low noise ventilation for residential properties. Ideal for kitchens, bathrooms, en-suites, utility rooms and WCs, it provides a flexible and energy-efficient solution for maintaining healthy indoor air quality.

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

Energy Efficient Performance

Powered by a low wattage DC motor, the Quro QRST offers reduced energy consumption without compromising airflow performance. Its aerodynamic design and constant volume technology ensure that selected airflow rates are maintained across a range of pressures, preventing nuisance running and eliminating the need for manual adjustment.

• Maximum airflow: 30 l/s (108m³/hr)
• Ultra-low SFP down to 0.08 W/l/s (SAP PCDB listed)
• Whisper-quiet operation below 9 dB(A) at 3m
• Constant volume control with limiter
• Low energy DC motor for improved efficiency
• 3 year manufacturer warranty

Automatic Intelligent Timer

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

User-Friendly Digital Controls

A convenient side-mounted display allows straightforward control of fan speed and timer settings. The interface also provides runtime information, operational status and diagnostic error codes for simple commissioning and maintenance.

Flexible Commissioning Options

The Quro QRST offers five selectable trickle speeds of 5, 8, 11, 13 and 16 l/s, factory set at 8 l/s, allowing the unit to be tailored to suit the specific needs of the property. Boost speeds are selectable between 20 and 30 l/s, factory set at 25 l/s.

Typically installed in a central hallway or landing, the unit gently ventilates the home to transform stale, stagnant air into a fresh, healthy and condensation-free environment.

Low Maintenance Design

Designed for fuss-free maintenance, the Quro does not require filters. The front cover can be easily removed and wiped clean with a dry cloth, helping to reduce long-term maintenance costs.
