Profile: Hitachi Home Electronics America, Inc. specializes in automotive products. Our product line includes televisions, power tools, hard disk drives, compressors and generator. Our DSP oil free rotary screw air compressors-single stage fixed speed provides stainless steel rotors which eliminate corrosion and promote the adhesion of the coatings. The cooling air path of the hi-precooler maximizes thermal efficiency of the cooling system. The standard motorized isolation valve (MIV) automatically closes the discharge when the DSP air compressor stops, protecting major components. The E-series vortex blower can be utilized in both discharge and suction applications. The E-series vortex blower is designed to provide non-pulsating air flow.
