5-2 Specifications
This section provides the specifications of the SJ-M201 Series.
■ Static Elimination Head/Controller Unit
*1: Values obtained at an installation distance of 50 mm and air flow rate of 60 Nl/min (ambient operating
temperature +20 to +30°C, ambient operating humidity 40 to 60% RH) (without nozzle)
*2: Values obtained at an installation distance of 50 mm and air flow rate of 20 Nl/min (ambient operating
temperature +20 to +30°C, ambient operating humidity 40 to 60% RH) (without nozzle)
*3: Inquire for derating of humidity/pressure in environments exceed +35°C.
Use clean, dry air at a temperature of -20°C or less. Air pressure varies
by the model of nozzle used (see the chart to the right).
*4: During regular use, supply air at a supply temperature of +40°C or less.
*5: These values are for the High-pressure Cable Unit only. The ambient
operating temperature is 0 to +40°C for other parts.
*6: When the ambient temperature exceeds +40°C, perform derating
according to the following figures.
