  • Air delivery is converted at intake conditions at atmospheric pressure and 30°C. As for guaranteed value of air delivery, please contact us if necessary.

 

  • The high-pressure specifications are an option at the time of manufacture.

 

  • Be sure to use Long-Life SP genuine Hokuetsu compressor oil.

 

  • Weight figures in parentheses show the weight of the unit without dryer.

 

  • The noise value is converted to anechoic chamber conditions at a distance of 1.5 m from the pump front (operating side) and a height of 1.2m (1.0m for SMS15/22/37) when the pump is operating at full load. Depending on the installation environment (effects of surrounding reverberation, etc.), the noise level when the system is actually installed may be higher than the level indicated here. The noise level also changes when the capacity control operation is in effect.

 

  • Outlet dew point is at an ambient temperature of 30°C.

 

  • When using in cold weather regions (2°C or below), the optional tape heater is required. (Cold weather region specifications).

 

  • Discharge air pipe diameter is 32A (1 ¼’’) for specifications without dryer. * A separate air tank with sufficient capacity must be installed. * The listed weights of oil-free models are the weights before installation of the Top Runner Motor.
