Ventilating Ceiling Ducted Dehumidifier CD-F Series introduces partial fresh air from outdoors and mixes with the indoor return air. The mixed air will then pass through the first stage (G4 efficiency), and second stage (F7 efficiency) air filtration to remove airborne particles and contaminants. The partially filtered air will then enter into the direct expansion dehumidification system to remove the excess moisture. The excess moisture in the air will be condensate and turn into water. The water will then be collected at a drain pan, where it will be pushed out with the help of positive air pressure from the processed air. The dried air will then pass through the final stage of the HEPA filter to remove micron size particles and airborne bacteria. The final output of the processed air will be dried and cleaned.

This system is suitable for applications that require the introduction of fresh air into the room and also that require to create of positive air pressure. This system can also be the replacement of the traditional ventilation fan that is used to keep the room filled with fresh air.

With CD-F Series, the supplied of fresh air would help to prevent issues that may affect the well-being of occupants due to lack of oxygen. Besides, it also help to reduce the growth of airborne bacteria with the built-in air purification, ensuring continuous supply of  fresh, clean and dry air is supplied into the room.
