As a result of increasing energy costs and the importance of reducing CO2 emissions, air filter energy consumption has become the focus of attention.
Energy Efficient Air Filters
It is possible to reduce energy consumption that is produced by your filters by using more energy efficient air filters. However, there are a few changes that will need to be made to your air handling system to accommodate this.
If your fan is constantly operating at a fixed speed, this will lower the average pressure drop of the air filters. Consequently, this will produce an increased air volume flow rate. As a result, the fan may be operating in a region with lower efficiency which causes increased overall energy consumption. Energy efficient air filters require the speed of the fan to be adjusted to supply a constant air volume flow rate.
Air Filter Energy Consumption
The energy consumption of air filters can be determined using several factors:
- The volume flow rate
- Fan efficiency
- Operation time
- Average pressure drop.
