ComfoAir Q350 PL L VV TR ERV recuperator, left version, enthalpic. Ventilation unit with heat recovery 350 471502072

Heat recovery ventilation unit – comfort and energy saving

Zehnder ComfoAir Q350 PL L VV TR ERV is a central ventilation unit with heat recovery, designed for efficient ventilation of single-family homes. The device combines high performance, quiet operation and intelligent control, providing an optimal indoor climate with minimal energy consumption. This model features an enthalpy exchanger that recovers not only heat but also moisture, which improves comfort and prevents air from drying out. The left-hand version (L) allows for flexible mounting on the wall or floor, and the possibility of converting to a right-hand version (R) expands the range of applications.

Technology for demanding users – performance and functionality

ComfoAir Q350 PL L VV TR ERV is an advanced solution for people looking for modern ventilation systems. Built-in sensors automatically regulate air flow, temperature and humidity, ensuring ideal conditions in every room. The modulated pre-heater (VV) adjusts the temperature of the supply air to external conditions, minimizing energy losses. Adjustable connection spigots (TR) facilitate installation and adaptation to specific needs. The cross-current heat exchanger with a large surface area ensures efficient heat recovery – up to 95% – which translates into significant savings in heating costs.

Advantages for installers and users

• High efficiency: 350 m³/h at 200 Pa ensures effective ventilation even in larger rooms.
• Moisture recovery: The enthalpy exchanger prevents air from drying out in winter and maintains optimal humidity levels throughout the year.
• Quiet operation: The quietest fans on the market guarantee almost silent operation of the device, which is particularly important in bedrooms and children's rooms.
• Intelligent control: Built-in sensors and the ability to connect to ComfoSwitch C, ComfoSense C and ComfoConnect LAN C systems provide full control over the ventilation system.
• Flexible installation: The possibility of wall or floor mounting and the option of converting to a right-hand version (R) facilitate installation in various types of buildings.
• Energy saving: High heat recovery and a modulated pre-heater minimize electricity consumption, reducing operating costs.
• 25% larger heat exchanger surface area: Compared to competitive solutions, it provides better heat recovery and lower thermal load on the building.
• Flow Control regulation: Automatic balancing of supply and exhaust air guarantees maximum heat recovery without the need for manual adjustment.

The Zehnder ComfoAir Q350 PL L VV TR ERV central unit is an investment in a healthy indoor climate and energy savings – a solution appreciated by both professional installers and end users.
