NOISE LEVEL
1.The values are specified at the static pressure of 0 Pa.
2.The values of noise level is A weighted average sound pressure level,the mean value
measured by our company,3 and -7 tolerance.
3.The values of noise level measured at the 1m apart from side of the fan body.
(When ducts are connected on both the discharge and suction sides.)
4.The values of air volume are the mid-points of results measured by our company,with 10% tolerance.
