The unique design and construction, with leakage, phase and overload protection device, ultra-small size is particularly applicable to the work area is small, but continuous dust generated by the work area. There can be mounted on a large-scale equipment, as a fixed vacuum devices, with the production equipment. Features: compact body, suitable for narrow work areas; low noise for quiet working environment; with overload, filter, phase protection switch; can last 24 hours working parameters: Technical parameters Technical Parameters Model Modle PM0075 PG0075-G PM0175 PM0175-G PM22 PM22-G PM34 PM38-G Voltage Voltage (V) 380V 380V 380V 380V Power Power (KW) 0.75KW 1.75KW 2.2KW 3.4 KW suction Max.Vacuum (kpa) 14Kpa 21Kpa 22Kpa 26 Kpa Noise Noise Level ( db) A 63dB 70dB 72dB (A) 72dB (A) the amount of wind Airflow (m3 / h) 144 m3 / h 216 m3 / h 312 m3 / h 312 m3 / h Weight Weigh (kg) 30kg 38kg 50kg 53kg Dimensions Dimensions L x W x H (mm) 750 * 450 * 690mm 765x460x720mm
