Note 1: Pressure unit [MPa] in the table 2-4 means gauge pressure.
Note 2: The J-series compressors must be used within the allowable operation range defined in the
table 2-4 and next page, Figure2-1.
When using J series in the explosion-proof area, use certainly in the condition with the
maximum suction temperature of equal to or less than 50 °C, the maximum lubrication
temperature of equal to or less than 55 °C (Refer to Note).
It is important specifically in the Application limits each clause eyes.
Note: When exceeding 55 °C, consult us for the further study because the maximum
lubrication temperature limitation is related to the atmosphere temperature, too.
