Ambient air Debris Moisture Air compressor Piping Contaminated compressed air Rust Piping debris Oil Carbon Problems with compressed air Compressed air is made by compressing ambient air. In this process, other substances are taken in with the air. Significance of a dryer Compressed air includes foreign objects such as moisture (water vapor, water droplets), oil, debris. Water droplets, oil and debris can be removed using air filters, mist separators, etc., but it is necessary to eliminate water vapor by using a dryer. 113 l = 1.8 l x Approx. 63 bottles In fact, this is how much moisture is included in compressed air. Compressor output: 75 kW, Air at 30°C and a relative humidity of 80% is compressed to 0.7 MPa for 8 hours. Moisture Odors Dust particles exceeding 3 μm (Solid contents) Dust particles less than 3 μm (Solid contents) (Water vapor) (Debris) Air impurities Compressed air not including impurities Air compressor After cooler Air tank Refrigerated Micro mist Air filter separator Main line filter Mist separator Odor removal filter (Deodorization) Compressed air impurities Air Preparation System air dryer 2
