Kair Mini Single Room Heat Recovery Ventilator – Prevents Condensation & Recycles Heat
The Kair Mini Single Room Heat Recovery Ventilator (Model: KSRHRV100-WH) is a compact, wall-mounted ventilation solution designed to combat condensation, reduce humidity, and recover heat. Ideal for bathrooms, kitchens, bedrooms, or utility rooms, it extracts stale air and delivers fresh, filtered air while recycling heat through a high-efficiency ceramic regenerator. Easy to install and low-maintenance, this unit offers powerful performance in a discreet, energy-efficient design.

General Product Information
The Kair Mini SHR Ventilator is ideal for maintaining a healthy indoor environment in single rooms. Its compact cartridge design houses a fan and heat regenerator that alternately extract and supply air every 70 seconds, retaining heat and humidity to minimize energy loss. Units can be paired in master-slave networks for balanced airflow.
Energy Efficiency
Rated as a Class II appliance, the unit consumes between 1.6W to 5.5W (normal operation), with minimal thermal loss thanks to the ceramic regenerator. The auto damper further prevents backdrafts, and standby modes help conserve energy.
Health Dividend
Designed to reduce condensation, mould, and pollutants, the Kair Mini HRV promotes cleaner air and stable humidity. It’s particularly helpful for allergy and asthma sufferers, enhancing overall air quality without increasing heating bills.
How It Works
In regeneration mode, the ventilator operates in 2 cycles:
Cycle 1: Warm, stale air is extracted through a ceramic regenerator, which stores heat and moisture.
Cycle 2: Fresh air is drawn in and passed through the regenerator, recovering heat and humidity before entering the room.
This cycle repeats every 70 seconds. Paired units operate out of phase to ensure balanced extraction and supply.
