The FLX REKU ventilation system is a next-generation household ventilation system designed for intelligent, room-by-room distribution of fresh air. Developed by Alnor — a trusted HVAC expert with over 30 years of experience — FLX REKU delivers precise airflow control, high energy efficiency, and a healthier indoor environment.
As a standout among smart home ventilation systems, FLX REKU not only improves air quality but also reduces heating demand, making it the ideal solution for homes that prioritize comfort, health, and sustainability.
The FLX REKU home ventilation system is a compact, high-efficiency solution dedicated to single-family homes. Unlike basic air exchange units, it offers a whole-house ventilation system that supplies fresh, filtered air while extracting stale air — all with minimal heat loss thanks to its built-in reku heat recovery unit.
By capturing thermal energy from the outgoing air and transferring it to the incoming stream, the system ensures a balanced indoor climate with lower energy consumption. Its integrated components — including sound-insulated ducts, silencers, diffusers, and smart flow regulators — work together seamlessly to enhance indoor air quality throughout the home, without noise or disruption.
FLX REKU is engineered to be the best home ventilation system for households seeking long-term health, efficiency, and control.
It continuously removes airborne pollutants, allergens, moisture, and odours, significantly improving indoor air quality and helping to reduce respiratory issues — especially in sealed, energy-efficient homes. As indoor air pollution is a growing concern, FLX REKU provides year-round protection and peace of mind.
Reku heat recovery technology drastically cuts energy consumption by reusing warmth from extracted air, resulting in noticeable reductions in heating bills. The system is both smart and adaptive — with intelligent air distribution that adjusts airflow based on occupancy, time of day, or activity. Whether you're cooking, sleeping, or relaxing, FLX REKU tunes ventilation for optimal comfort.
Despite its performance, FLX REKU remains whisper-quiet thanks to acoustic insulation and precision-engineered silencers. Maintenance is quick and simple, and its durable, modular design ensures reliability for years. More than just a system — FLX REKU is an investment in a healthier, more comfortable home.
The house ventilation system operation behind FLX REKU blends technical precision with everyday simplicity.
Fresh air is drawn from outside, purified through high-grade filters, and passed through the system's heat recovery ventilation unit. Using reku technology, thermal energy from outgoing air is transferred to the fresh incoming air — keeping interiors warm in winter and cool in summer without energy loss.
Tempered air is then distributed evenly to living spaces, while stale, humid air is extracted from moisture-prone rooms. FLX REKU goes a step further with built-in sensors that monitor humidity, temperature, and CO₂ levels, automatically adapting airflow to keep conditions optimal.
FLX REKU ventilation heat exchange mode adjusts seasonally — conserving heat in colder months, and bypassing it in summer to prevent overheating. Homeowners can also manage settings manually via a smart panel or mobile app, tailoring the system to individual needs and routines.
The FLX REKU home ventilation system is designed for flexibility — making it ideal for both new-build homes and retrofit projects. From compact urban flats to spacious family houses, FLX REKU can be tailored to suit virtually any layout or size.
In new developments, it's easily integrated during the planning stage. For renovations, FLX REKU's modular, space-saving components make retrofitting ventilation systems simple and minimally invasive. Its low-profile design requires little technical space, while ensuring optimal airflow distribution.
Standard home ventilation system installation is completed within days by certified professionals. Alnor supports the full process — from consultation and design to commissioning — guaranteeing compliance with building regulations and energy standards.
Additionally, in many regions, the system qualifies for energy efficiency grants and subsidies, helping reduce upfront costs and accelerate your return on investment.
FLX REKU is more than just a ventilation product — it's a fully integrated solution backed by the engineering excellence of Alnor, a brand recognized throughout Europe for its HVAC innovation and reliability.
Combining smart home ventilation solutions with silent operation and robust construction, FLX REKU enhances indoor air, reduces energy usage, and increases property value. It's a long-term choice that pays off in comfort, health, and savings.
