Understanding Unducted Air Cleaner Systems
There are two main ways that Electrostatics air cleaners capture air, source capture systems and unducted systems, also known as ambient or free air. Source capture still stands as the most recommended and efficient way to capture air but in some cases our customers find an unducted capture to be the best solution for their operations.
Success with unducted systems is created by establishing a recirculating air flow in your space. The airflow is established by having the clean airflow from one precipitator blow across to the intake of the next precipitator which collects the rising pollutants along with it. A key point to remember is the overall performance of the unducted system will come out of the ability to properly create a recirculating air flow. Two examples of air flow patterns are below. These are shown using Smog Hogs SG-4-T models.
Unducted systems must be designed properly to see effective results. Some design considerations to consider are the size and shape of your space, existing air and ventilation equipment, having the right filtration equipment to match your design specifications and how many air changes per hour. Below is a graphic showing the recommended air changes per hour. Another way to determine how frequently to change the air over is to notice how soon after starting your machines the room is too smoky.If it is too smoky at 10 minutes, you need to change the air more than six times an hour. In other words, if you turn the air over six times an hour you will always have 10 minutes of smoke in the air.
