It is used for the ovalizer duct manufacturing. After spiral duct,the ovalizer duct machine expands it into standard size,with the character of good shape,high efficiency,easy operation.

It is indispensable for duct manufacturing. Machine control is by PLC, and the LCD unit on the operator‘s panel stores all set parameters for easy recall by the operator when required.

Advantages of oval ducts rather than normal spiral ductworks,

» Better airflow
» Easier to install
» Less joints
» Less hangers
» Often requires less space
» Corrugation for added strength
» Modern design

hydraulic flat oval duct machine

Product Description
The oval duct is formed by round spiral duct that is stretched and deformed upward. The design of the oval duct forming machine plays a big role. The newly upgraded oval duct forming machine has increased the capacity of the cylinder on the basis of the original, so that the diameter of the processing is larger, the expansion makes the joint more precise and does not rebound.
Preda oval duct forming machine is easy to operate, and it can be easily operated after being filled with oil. It is a more practical equipment in the air duct production industry.
