3 in 1 MULTI DRY FILTER for Compressed Air

Case 1: Automotive manufacturer

Coating production line for Japan’s leading automotive manufacturer

1. Issues
Coating defects were a problem, even after installing 0.01μm filters, and they often had to re-paint the body.
2. Investigations
Air quality was measured with a laser particle counter, and caught impurity particles of over 0.3μm at quantities of 1,200 pcs/l. Based on these results, it was clear that these impurities were a root cause for coating defects.
3. Solutions
Maeda Shell Service’s 3 in 1 Multi Dry Filters were installed in areas of air supply for drying, overcoating and clear coating, which solved the problem.
4. Results after installation
– Airborne impurities over 0.3μm were reduced from 1,200 pcs/l to 0 pcs/l.
– No painting defects due to compressed air

Case 2: Food Industry

Bread production

1. Issues
Packings were inflated with air, however there were no high performance air filters installed in the packaging system. As a result, molds were growing within shelf-life.
2. Investigations
Impurity particles of over 0.3μm were found at quantities of 10,000 pcs/l when the air quality was measured. These results clearly states that those bacterias in air were causing the breads to mold.
3. Solutions
Maeda Shell Service’s 3 in 1 Multi Dry Filters were installed in the packaging process,  as well as at the bread depanner, airblow and any other locations where air was directly contacting the product.
4. Results after installation
– Impure particles over 0.3μm found in air were reduced from 10,000 pcs/l to 0 pcs/l.
– Mold free shell life of baked goods
– Contributing to food safety

Case 3: Machine tool

Precision metal processing industry

1. Issues
Air and oil was supplied to the main axis in order to cool and lubricate it. Galling is a common problem in metal forming and it had been a problem at this company too, costing them around US$ 8,000 to repair the main axis.
2. Investigations
The manufacturers knew the quality of air was causing the problem and they requested to urgently solve the problem. When air quality of the factory were measured, impurity particles of over 0.3μm were found at quantities of 430,000 pcs/l.

3. Solutions
Maeda Shell Service’s 3 in 1 Multi Dry Filters were installed at the main axis.
4. Results after installation
– Impure particles over 0.3μm were reduced from 430,000 pcs/l. to 0 pcs/l.
– No galling were caused
– No need to repair the main axis
