●It is a cooling method that does not use cutting fluid unit.●Cooling air is 31●C lower than the outside air.●To cool the blade edge and cool the workpiece during cutting.●Air Consumption (L/min):230 to 490●Working Air Pressure (MPa):0.2 to 0.5●Connecting Screw:R1/4●Adaption fluid: air●Hose Nipple●If it is not clean air, clogging may occur and the cooling capacity may fall.
