Key Features

Technical Highlights

The AHE25NB steps up to Ø150 mm ducting, supporting longer duct runs and more supply/return outlets — covering 2-bedroom apartments and small villas without oversizing the unit or compromising noise performance.

Dual PSY Polymer Cores
Dual PSY Polymer Enthalpy Cores
Two washable PSY polymer enthalpy cores, 92% total energy recovery at rated 250 m³/h flow. Polymer construction transfers both sensible heat and moisture — maintaining indoor humidity balance in both winter heating and summer cooling modes. Cores rinse clean under running water.
DC Brushless Fan Motor
70W BLDC Centrifugal Fan
25 dB(A) at minimum speed. At 250 m³/h, the Ø150 mm centrifugal fan delivers adequate static pressure for multi-room duct networks. Variable speed control (30–100%) enables demand-controlled ventilation when paired with CO₂ sensors or smart home integration.
Slim Profile
Ceiling-void Friendly Design
986.5 × 641 × 228.8 mm body fits within the standard ceiling cavity of most 2.7–3.0 m ceiling height apartments. Tool-free access panel for filter and core maintenance. Standard G4 coarse pre-filter + F7 fine filter combination captures pollen, dust mite debris, and urban particulates.
