Discarding of primary filter
FEATURES
- The wedge-shaped pleats have the largest filtering area, and the airflow can help to collect dust. It is widely accepted in high performance and long-term needs.
- It is also suitable for variable air volume systems. It can be installed in the box by using the clip.
※ The filter screen can be flexibly designed according to customer needs, and the material, origami thickness, filter efficiency, air volume and air inlet size can be selected.
※ Various sizes, specifications and any special functions can be customized.
※ All kinds of special customized designs, there are too many types to be uploaded, please inquire and refer to the actual performance unit.
