The casing is high reinforce and high temperature resistant engineering plastic. There are two types of structure: single impeller structure and double impeller structure. The lives of double impeller air blowers are longer than the single impeller ones. The differences of air pressure and air flow between single impeller ones and double impeller ones are inconspicuous. Compare the data of noise, although the dB(A) value of double impeller air blower is only 2 or 3 points lower than single impeller air blower, the high-frequency noise of double impeller air blower is much lower than single impeller air blower in peoples' hearing.The wind of double impeller air blower is soft and comfortable. They are the first choice products for hydromassage bathtub and SPA large pool which making bubble.
Motor: low-noise air blowers' dedicated excitation motor which with dedicated thermal protection (VDE or UL approval) that can protect the motor. Insulation class F and with thermal protection from T.I. The carbon brush of the motor is import material. The life is greater than or equal to 1000 hours (continuous duty).There is fuse inside the motor, pneumatic switch control for easy operation.
