Luchtcompressor regelklep, 1/4in drukschakelaar 220V 380V 20A voor vervanging

So, here is my report after i bought this Air Set:Pressure Switch: Very nice Quality outside and inside, the red button needs little grease inside of the cap, it will work more easily, there are not screws for the Ground cables (you can use your old ones, no problem).Works perfectly, stops at 8 Bar, really nice.Safety Valve: Small valve with double outlet, good Quality, works perfectly.Gauges: Again very nice Quality, beautiful, work perfectly.Air pressure Regulator: 2-3 Stars Review, little difficult to turn even after greasing, i dismantled it completely, there was a big metal chip left inside the holes, i deleted it.It is not written which is the inlet on it (the hole that you can see the spiral coil inside is the inlet).Be careful not to tight the connectors very deep on it because it will break up (i used teflon tape and not glue, i used the red plastic washers in the photo for this purpose).It has two outlets which is good of course so you can use two air tools at the same time, i would prefer one outlet with full air pressure from the air tank and one with regulated air but it's ok.After all it works fine but it is not the best as the rest parts of the set.Air Connectors: They look nice and good Quality, little difficult to disconect the air hose, maybe after use they will get better, no leaks, i also lubricated them with Oil spray, they need it.Generally is a good Air Set, it is Chinese but really good Quality (except the Air Regulator).Advice:Grease (Switch Button, Air Regulator Knob) , Oil Spray ( Switch Mechanism inside, Air Hose Connectors, Safety Valve) , Gauges (No lubrication! Not recommended!) and you done!Your New Air Set will work perfectly and will last longer.As an old customer, Many Thanks to Amazon for the good products and for the good Service.
