Abstract

The main component of air filter in Air Handling Unit (AHU) is to trap the air contaminant in air and supply to space. Most people will choose pleated filter as the main type of filter in AHU and also as pre-filter. The efficiency and pressure drop of the filter can be shown in difference filter angle. This study aim to design and fabricate the prototype of air filter test rig based on ASHRAE standard 52.2 and EN 779. The efficiency of air filter in the test rig placed in 30°, 60° and 90 of angle also are determined. Heterogeneous of fiber arrangement in air filter will more effective to remove air contaminant and cause the pressure drop will suddenly decline in the middle of process when the dust cake reached certain high. Also, the thickness of dust cake will increase the efficiency and pressure drop of air filter. The air flow rate is 600m3/h until 6000m3/h and the U-shape of air filter test rig based on ASHRAE 52.2 standard. Hence, the test rig had been design in U-shape with the size of 610mm (H) x 610mm (W) and the formula to calculate the air flow range is 0.64m/s until 4.48m/s. The fan speed in this experiment is 1986.5rpm. The highest efficiency of air filter angle is 90°. Although the angle of 60° had the largest difference of pressure drop and permeability, but the angle of 90° had the high face velocity than 60° in starting point. Hence, the pressure drop and permeability of air filter will keep increase and decrease respectively after starting point. In conclusion, we can said that angle of 90° is more efficiencies than angle 60° to trap the air contaminant at the starting point.
