Drainage-related malfunctions

When your air tool stops working, the most common cause is rust inside the air tool caused by moisture contained in the compressed air.

Air normally contains moisture. The maximum amount of water vapor that air can contain is called the saturated water vapor content, and it changes depending on the temperature and pressure.

Air tools use compressed air, so a compressor is required. When air is compressed, the saturated water vapor content decreases. This causes moisture to form inside the compressor (this is called drain water).

This water enters the air tool along with the compressed air and corrodes the parts.

The photo above shows an air tool rotor corroded by condensate. This condition will prevent the tool from working. Even a brand new tool can become inoperable within a week if a large amount of condensate gets into it. When using an air tool, be sure to pay close attention to condensate. Methods for removing condensate include:

1. Install a dryer on the compressor.

(Currently, compressors with built-in dryers are the mainstream.)

2. Install an air filter midway through the piping.

3. Add a drop or two of turbine oil to the air inlet before and after using the air tool.

By following these steps, you can significantly reduce air tool malfunctions. (Failure to remove condensate will also affect the compressor's lifespan.)

If a part becomes corroded as described above, please return it to the manufacturer or take it to a nearby repair shop. We will remove the corrosion and repair it. However, in this case, disassembly and adjustment fees will be charged.

Also, internal rust may be caused by factors other than condensate. The amount of saturated water vapor also changes depending on the temperature. It decreases as the temperature drops, so if the piping is long, the air temperature is often lower than the temperature inside the compressor, causing water droplets to form inside the piping. This can lead to corrosion of the piping, so slope the piping and arrange for the drain to collect in a uniform location, and also drain the drain. The best way to prevent this is to install an air filter.

When using air tools, please take care to prevent moisture from entering the air tool itself. This will significantly extend the life of the compressor, piping, and air tool itself, and is more environmentally friendly.
