HERU 15 R – ROOM VENTILATOR
HERU 15 R – Room Ventilator with Smart Energy Recovery
COMPACT VENTILATION FOR SMALL SPACES
A “MINI UNIT” WITH HIGH CAPACITY – EVEN WITH FILTER
HERU 15 R is an efficient room ventilator that provides balanced, bidirectional and continuous ventilation – perfect for tiny houses, apartments, offices, site cabins and other smaller spaces where traditional ventilation solutions are oversized.
Despite its minimal dimensions (220 × 270 × 110 mm), HERU 15 R delivers impressive performance and high comfort. The compact design makes it ideal for locations where ducting is difficult to install, costly or aesthetically undesirable.
CENTRIFUGAL FANS FOR CONSTANT AIRFLOW
HERU 15 R is equipped with centrifugal fans that ensure a smooth and stable airflow throughout operation. This means that the air volume is maintained even when air passes through the integrated filter, providing reliable and efficient room ventilation.
Minimal Intervention – Maximum Effect
HERU 15 R is installed directly in the outer wall using only one installation hole – quick, easy and without extensive construction work.
FOUR SPEEDS – FOR AREAS UP TO APPROX. 40 m2
HERU 15 R features four ventilation modes adapted to different needs and is suitable for rooms up to approx. 40 m².
IDEAL FOR RENOVATION AND EXTENSIONS
HERU 15 R is perfect when you want to achieve energy-efficient ventilation:
• Extensions
• Garages
• Komplementbyggnader/ tiny houses
• Rooms where ventilation is missing or insufficient
• Areas where ducting is impractical
Better Health, Better Sleep, Better Air
With the option to use allergy filters, HERU 15 R supports cleaner indoor air, helping to reduce allergy exposure and create a healthier indoor environment – day and night.
ENERGY SAVINGS AND FAST PAYBACK TIME
With high heat recovery and low energy consumption, HERU 15 R provides a short payback period. Ideal for those who want to improve energy performance without major installations.
HIGH EFFICIENCY – AT REAL AIRFLOWS
The product is designed to deliver consistently high and even energy recovery at nominal airflow. This makes HERU 15 R a reliable choice where high energy efficiency is required
Key Benefits
• HIGH PERFORMANCE – EVEN WITH FILTER HERU 15 R uses high-performance centrifugal fans that provide a stable airflow. The unit is always equipped with filters for cleaner air, safe operation and more even ventilation.
• COMPACT DESIGN – 220 × 270 × 110 mm
Its extremely compact construction requires minimal space and fits even where space is limited.
• TRUE TWO-WAY AND CONTINUOUS VENTILATION
Unlike many common solutions, HERU 15 R delivers continuous and balanced airflow – for better comfort, better air quality and higher energy efficiency.
• DECLARED EFFICIENCY AT REAL AIRFLOWS Efficiency is stated based on nominal airflow, giving a transparent and honest picture of actual performance over the year.
• HEAT AND MOISTURE RECOVERY FOR IMPROVED INDOOR CLIMATE
The built-in enthalpy exchanger recovers both heat and moisture to the supply air, reducing the risk of dry indoor air in winter and creating a more comfortable climate.
• HIGH ENERGY EFFICIENCY AND FAST PAYBACK
• BETTER AIR – BETTER HEALTH
Continuous and even air exchange creates a more pleasant indoor environment and helps remove stagnant air.
• MINIMAL INTERVENTION – MAXIMUM VENTILATION EFFECT
Installation requires only one wall opening. No ducting, no major construction – just efficient ventilation that is easy to install and maintain. Can be installed in an existing 160 mm duct.
By recovering a large share of heat from extract air, the need for additional heating is reduced, resulting in lower operating costs.
• OPTIMAL SOLUTION FOR EXTENSIONS AND RENOVATIONS
Makes it easy to meet ventilation requirements in extensions, garages, Attefall houses and other small spaces.
• PERFECT WHERE TRADITIONAL DUCTING IS NOT POSSIBLE
Ideal for difficult-to-access areas, small houses, cabins or architecturally sensitive environments
• MORE COMPACT THAN COMPETITORS
Significantly smaller than comparable products on the market – without compromising on performance or capacity.
