Product Description
The Astberg AF125 is a silent mix-flow inline duct fan that has been meticulously developed to offer the best airflow while remaining quiet. It provides maximum performance with minimal noise, with an output of 284 m³/h (167 CFM) and an operating loudness of only 31 dB(A).
It is wide-duct capable, and its mixed-flow impeller design generates a high static pressure (159 Pa), which favors short duct work over lengthy runs or complex ventilation systems.
It contains a complete ABS plastic casing with multilayer insulation, making it lightweight but durable enough to withstand years of continuous use.
The speedy installation and low maintenance AF125 can be employed in both residences and light commercial vent requirements, especially where a gracious sense of stillness is silvered with gold.
