Frequently Asked Questions
What is the ambient air humidity range for the ARW1?
The surrounding air humidity range is -40P to +40P, with a 24-hour average value not exceeding +35P. The lower limit is -40^ unless specially declared.
What is the maximum altitude limit for the general type ARW1?
For the general type, the altitude must not exceed 2000m. If used above 2000m, it must be operated with reduced capacity.
What is the maximum altitude limit for the plateau type ARW1?
The altitude limit for the plateau type of ARW1 must not exceed 5000m.
How does temperature affect the permissible relative humidity for the ARW1?
At a maximum temperature of +40P, the relative humidity must not exceed 50%. However, higher relative humidity is allowed at lower temperatures, such as up to 90% at 20P.
What are the Pollution and Protection classes for the ARW1?
The ARW1 is classified under Pollution Class: Class 3 and Protection Class: IP30.
