I bought it for improving work efficiency.
Because it has a lot of air volume, it can not be used if the output of the compressor is small.
With a 2.2 kw compressor, pressure drops to 5 kg or less when it is used continuously, so I think that it is not suitable for work requiring wind pressure.
However, if the compressor is 3.7 kW or more, there is no pressure drop and considerable improvement in efficiency can be expected. I think that it is still only expected value because it is not used for work at the site yet.
However, I'd like you to keep the price a little more. After that, the freedom of connecting plug was not so necessary for me.
