Increased discharge pressure
The blower temperature rise has been reduced through the use of a new tooth profile and the improvement of the radiation mechanism. At the same time, the burden to the grease has been reduced. As a result, the maximum discharge pressure has been increased to 50kPa {0.51kgf/cm } for models ARH20S to ARH40S and 60kPa {0.61kgf/cm } for ARH50S and higher models. All models permit the use of ordinary grease available on market.
