Key Features
Products Design
Adapts To 270-500 mm Walls
Designed for versatile installation, this mini single-room energy recovery ventilator adapts to wall thicknesses from 270 to 500 mm. Combined with a compact 120 mm installation hole, it allows easy retrofitting in different building structures while minimizing wall damage—ideal for both new installations and renovations.
97% Regeneration Efficiency
The ECO-PAIR 1.2 features a high-efficiency ceramic energy accumulator with up to 97% regeneration efficiency, effectively recovering heat from exhaust air to condition the incoming airflow. Choose between Honeycomb or Heat Storage Ball regenerators for optimal energy savings and comfort.
Suitable for All-Season
Summer: Recovers indoor cooling and humidity, reducing air-conditioning load and preventing stuffiness.
Winter: Recovers indoor heat and humidity, lowering heating energy consumption and preventing dryness.
Winter: Recovers indoor heat and humidity, lowering heating energy consumption and preventing dryness.
32.7 dB Ultra Quiet*
The EC motor fan, located near the outdoor side, operates at ≤32.7dB(A), ensuring ultra-quiet performance. Perfect for bedrooms and studies, it uses a brushless DC motor for silent operation, (*Tested under internal laboratory conditions at its lowest speed setting for optimal quietness.)
Smart & Stable Control
Easily pair two units within 1 minute without the need for cables. The Wireless Bridge feature allows seamless connection between a Leader Unit and a Follower Unit for efficient and stable control.
Optional F7 (MERV 13) Filter
Effectively traps PM2.5, pollen, and fine pollutants as small as 0.4μm. It helps remove harmful particles from your air, including: Smoke; PM2.5; Pollen; Airborne dust; Pet dander; Dust mites
