44、m2 shall be permanently equipped with a filter. The filter shall be made of corrosion resistant metal. If mesh filters are used, the unrestricted filter surface area shall be at least five times the sum of the gas flow areas in the component and the mesh of the filter shall be between 0,5 times and
45、0,8 times the smallest dimension of any passage in the gas flow. If sintered metal filters are used, the surface area of the filter in the gas flow divided by the porosity shall be at least five times the sum of the gas flow areas in the component. The manufacturer shall specify: - A-weighted sound
46、level over the pressure range; - pressure range; - type of supply gas; - maximum flow rate of supply gas in the specified pressure range; - minimum operating temperature: - 20 C or lower; - maximum operating temperature: + 50 C or higher. Where the manufacturer specifies extended temperature ranges,
47、 these temperatures shall be used for the requirement in 4.4 and the test in 5.5.
