EC motor enhances Advanced Air fan decks
The EC (electronically commutated) motors in Advanced Air’s horizontal fan deck have a chip developed by Nailor, the company’s American parent, which gives a pressure-independent unit and makes the fan-coil self balancing so that no commissioning is required on the air side.
The large horizontally mounted motors mean that energy efficiency is maximised, with specific fan powers of 0.15 W/l/s or lower. Also, with these slow-running fans, noise levels are much reduced, and NR25 has been achieved on a number of projects.
Advanced Air makes its own fan decks. Since most fan coils are batch produced, as opposed to mass produced, special designs do not create a problem or even a cost penalty.
