*1 At installation distance 50 mm 1.97", air flow 60 Nl/min (ambient temperature 20 to 30 °C 68 to 86 °F, relative humidity 40 to 60 %)
*2 Values obtained at an installation distance of 50 mm 1.97" and air flow rate of 20 Nl/min [ambient operating temperature +20 to +30 °C +68 to +86 °F, ambient operating humidity 40 to 60 % RH] (without nozzle)
*3 Inquire for derating of humidity/pressure in environments exceeding +35 °C 95 °F. Use clean or dry air at a temperature of -20 °C -4 °F or less. Min. air pressure varies by nozzle used.
*4 Use a supplied fluid with a temperature of 40 °C 104 °F or less.
*5 Only for the pressure cable. Other parts should be used with an ambient temperature of 0 to 40 °C 104 °F.
