From high-efficiency heat exchangers to advanced control options, we've got the capacities and capabilities to get the job done. has been designing and manufacturing attenuators and RF switching products since 1979. For ducted SDA type units, the attenuator cross-section should ideally be sized to maintain a maximum pressure drop of 10Pa. Square and rectangular duct shown in the drawings will have to be converted to equivalent round size. An air handler typically contains a fan, heating coils, cooling coils, a filter section, sound attenuators, dampers, actuators and controls, depending on the particular design. Variable attenuators are an integral part of most BER testing and EDFA characterization setups. Heating, Ventilation and Air Conditioning Product Manufacturers. Download youre free copy.
