h frequency conversion soft start, it avoids grid impact,self-engendered mechanical impact, and negative factors of lastinghigh speed operation of the air end. Without the participation of acontactor, it prevents point contact failure. Setting desiredpressure at discretion, and maintaining constant pressureUsers can set pressure between 3-14 bars at their discretion,without changing the gear of belt.When air use increases, the unit increases air output throughautomatic acceleration of rotational speed to avoid a fall inpressure and ensure air supply at constant pressure. When air usedecreases, the unit increases air output through automaticdeceleration of rotational speed to avoid a rise in pressure andensure continued air supply at constant pressure.Efficiency and energy conservationThanks to the variable speed control technology, the capacityof compressors can be perfectly combined with the air use of users,which downright avoids the unloading power loss. In intermittentair use, the zero load of soft start avoids the peak of current andtorque. Therefore, the speed of the units can be adjusted forlimitless times. Truly realizing steeples speed change andminimizing the loss of reactive power. Without the pressure burdenin excess of 2 bar, the unit can save energy directly by 14%.Thatis because every 1 bar operating pressure reduced can save energyby 7%. Specifications
