The thickness of AHU filters can vary depending on the type of filter and its efficiency. Here’s a general guideline:
Panel filters:
These are the thinnest, typically ranging from 1 inch (25 mm) to 2 inches (50 mm)
Pleated filters:
Their thickness varies based on the pleat depth, usually in the range of 1 inch (25 mm) to 4 inches (100 mm).
Bag filters:
As deep pleated filters, they are the thickest option, commonly ranging from 2 inches (50 mm) to 12 inches (300 mm) or even more.
HEPA filters:
While HEPA filtration media itself is thin (around 0.5mm to 1mm), HEPA filters are often constructed with pleats to increase surface area and fit within a frame. Their overall thickness can be similar to pleated filters, ranging from 1 inch (25 mm) to 4 inches (100 mm).
Carbon filters:
Their thickness can vary depending on the amount of carbon contained within the filter. They can be as thin as standard pleated filters (1-2 inches) or thicker depending on the application.
Important factors to consider:
- AHU design: The available space within the AHU will limit the maximum filter thickness that can be accommodated.
- Airflow requirements: Thicker filters can restrict airflow more. AHU capacity and desired airflow should be considered when selecting filter thickness.
- Efficiency needs: Higher efficiency filters, like HEPA filters, may require a thicker design to achieve the necessary filtration area.
It’s important to consult the AHU documentation or manufacturer’s (Contact Vipul Ac to learn about our HVAC Service Call +91 8000092000 ) recommendations to determine the appropriate filter thickness for your specific unit.
