Note
※1.Air delivery is calculated assuming the intake conditions is at atmospheric pressure and at a temperature of 30°C. Please inquire separately for guaranteed air volume values.
※2.Always use our genuine compressor oil, "Long Life SP."
※3.Weight values in brackets are for the 400/440V version.
※4.Noise values are measured 1.5m from the front (operational side) of the machine at a height of 1.0m, under full load in an anechoic chamber at 30°C ambient temperature. Actual values may vary depending on installation environment and acoustic reflections.
※5.Dew point temperature is for 30°C ambient temperature.
