VEVOR HEPA Replacement Filter, 24\'\'x24\'\'x11.5\'\' AC Filter, True HEPA Pleated Air Filter, Air Filter Replacement with Galvanized Frame, 99.97% Standard Filter Compatible for HEPA Filter Novair 20

The pressure drop or static pressure is not fixed. The higher the air volume, the higher the pressure. The recommended maximum throughput is 3400m³/hour. The pressure drop or static pressure is less than or equal to 220Pa at an air volume of 3400m³/hour. After a period of time, the pressure increases and reaches 450 Pa. It is recommended that you need to replace the filter.

The efficiency of the item is 2000m³/h,1cfm≈1.7m³/h.

If you use a single filter than an AC infinity cloudlift s14, you need at least a fan with CFM of 1K due to the thickness of this filter. Make sure to add a 2nd pre filter before this one to extend its life, a MERV value of 11-13 due to small pollen/mold spores will do great.

I am creating a flow hood with 2 of these and I will be placing 2 of those fans in a push from the top configuration. The fans come with a wireless remote and so it will be easy to adjust the speeds. As long as you can adjust the speed with sometype of potentiometer, you will be good. Turn the fan on and than place a candle in front of the filter, if you see movement toward you, it's a good speed, if not than keep increasing speed of that fan that you buy. see less If you use a single filter than an AC infinity cloudlift s14, you need at least a fan with CFM of 1K due to the thickness of this filter.

The exact answer to that question is still unknown but what I did was try different inline fans with a speed controller and used a BBQ lighter and adjusted the fan speed until I saw a steady flame being blown about 45 degrees in the direction the airflow was blowing.

In my case, I wound up using a 8 inch max fan fan with three speeds and keep it on the first speed even though it works it’s not ideal. If you wanted something more ideal then I would choose a squirrel cage blower that ran on a DC motor with a speed Adjuster on it. There are videos on YouTube that describe how to make a laminar flow hood. Those were a lot of help. see less The exact answer to that question is still unknown but what I did was try different inline fans with a speed controller and used a BBQ lighter and adjusted the fan speed until I saw a steady flame being blown about 45 degrees in the direction the airflow was blowing.
