HEVAC’s Air Distribution Manufacturers Group has thoroughly revised its Guide to Air Distribution Technology for the Internal Environment.
This guide is intended to be used by designers or contractors who install air diffusion equipment. HEVAC says that using the manual early in the design stage will assist both designers and contractors in obtaining a satisfactory air distribution system.
First published in 2000, the guide has been out of print for many years. The new format is a freely downloadable pdf from the HEVAC website http://www.feta.co.uk/associations/hevac/specialist-groups/air-distribution-group
