Air flow rate can be paid Down an average wind speed of approximately 0.33 m/sec wind and Inflow rate on average wind speed of approximately 0.53 m/s, while the work does not exceed 62 dBA.
Down flow rate of air supply to the average wind speed of about 0.33 m / s wind speed and wind Inflow rate of about 0.53 m / s, while the noise does not exceed 62 dBA.
Can supply wind Down flow in air velocity average 0.33 meters / second and wind Inflow have air velocity average 0.53 meters / sec. By working noise does not exceed 62 dBA.
