More air filter area, more airflow rate
Synthetic fiber, Panel and flat design
- Generally, the thickness of a flat pre air filter is between 10-25 mm. This thickness is generally not suitable for a pleated pre air filter. The flat pre air filter can provide a thinner thickness, which is more conveniently to use. The thickness of filter media is usually the same as the thickness of the filter 10-25 mm, with a fluffy construction, and one side may contain glue to absorb more dust.
- The flat pre air filter uses synthetic fiber as the filter material. When enough dust is collected to reach the rated dust holding capacity, it can be washed 1-2 times. However, multiple cleaning is not recommended, as water washing will damage the structure of the synthetic fiber and affect the filtration efficiency.
- The fluffy synthetic fiber has lower resistance, which can reduce the power consumption of the ventilation system.
