Thermal Insulation Type AIR DUCT FABRIC

This type are made of special material which with 3 layer, outside and inside layer are same material to standard type, However, medium layer will be a kind of rubber insulation material, thickness will be 13,20 or 25mm in total, This type used to be for area which has suspended ceiling and air duct has to be installed above ceiling. This type are able to to avoid unnecessary heat loss and improve our heat supply efficiency.

Air flow



The surface air

Surface air flows through the pipe surface of a breathable fabric, or air is distributed through micropores that account for at least 25% of the pipe surface area. Usually usedas a primary or secondaryflow pattern mixed with adirectional flow pattern.



microporous relating to the surface area of a pipe 25%-100%. Surface air flow is usually used to prevent dust or other particles from accumulating inside or on the surface of the pipe, resulting in little maintenance of the pipe.Also can prevent the formation of condensation in or around the pipe.





Directional airflow

Directional airflow can be used to accurately distribute one or more sets of airflow over theentire length of the pipe to the desired area.

Directional airflow is often used asthe main airflow to achieve short-range, medium-range, long-range air supply.
