<p><P>PROBLEM TO BE SOLVED: To provide a low-cost compressed air filtration device which is an energy-saving type having a simple constitution, requires no maintenance and whose maintenance cost is low and which can be easily applied to an air compressor used already. <P>SOLUTION: In the compressed air filtration device, a supply pipe 2 and a discharge pipe 3 for compressed air are disposed on the upper part, the supply pipe 2 for the compressed air is extended to the lower part in a chamber 1, where a drain pipe 4 is disposed on the bottom part, and an inverse funnel shaped expansion part 7 which is expanded near an inner circumference part of the chamber 1 is formed on the lower end of the supply pipe 2 for the compressed air. Preferably, the inside of the chamber 1 is divided into upper and lower parts by a filter 6, the supply pipe 2 for the compressed air is extended through the filter 6 and the inverse funnel shaped expansion part 7 which is expanded near an inner circumference part of the chamber 1 is formed on the lower end of the supply pipe 2 for the compressed air. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
