The LLFA Noise Dampening Cabinet is designed for FAM and FAH fans and is used to dampen noise dispersion into the environment. The noise dampening cabinet is designed for indoor use, but if required, it can be adapted for placement outdoors. The cabinet is manufactured from 1.5 mm thick aluminium zinc plates and is insulated with polyurethane foam together with a bitumen mat to dampen structure-borne sound. This dampens noise by approx. 15 dB in case of 50 mm insulation and approx. 20 dB in case of 100 mm insulation. The fan and noise dampening cabinet are supplied fully assembled with a round duct at the air inlet and outlet. The cabinet features a large door on one side enable easy access during electric installation, service work and inspection. Sleeve couplings, clamping ribbons and noise dampers are separately available for on-site installation. It features standard H2 air exhaust. Upon request, other air exhaust models are available.
