A two-way flow ventilation unit with purification but without heat exchange is a ventilation device that achieves indoor-outdoor air circulation through dual supply and exhaust channels, integrates filtration and purification functions, but is not equipped with a heat exchange module. Its core features are as follows:

Working Principle

Dual-flow design: Independent supply and exhaust fans work simultaneously to forcibly bring fresh outdoor air into the room while expelling indoor stale air, ensuring efficient ventilation. Air purification: Equipped with multi-stage filters (e.g.,HEPA, activated carbon) to remove pollutants such as PM2.5 and formaldehyde, with purification efficiency typically exceeding 97-99%.

No heat exchange: Unlike full heat recovery models, this device does not recover heat or coolness during ventilation, which may cause temperature fluctuations in winter or summer due to the temperature difference. Advantages and Use Cases

High-efficiency ventilation: The dual-flow design offers better ventilation efficiency than one-way flow systems, making it ideal for spaces with high ventilation requirements (e.g., living rooms, offices). Lower cost: Without the heat exchange module, the price is typically lower than that of full heat recovery models.
