NEW! Now  with both Imperial and Metric Values! Since its first edition in 1951, Industrial Ventilation: A Manual of Recommended Practice has been used by engineers and industrial hygienists to design and evaluate industrial ventilation systems. The 28th edition of this Manual continues this tradition. Renamed Industrial Ventilation: A Manual of Recommended Practice for Design (the Design Manual) in 2007, this new edition now includes metric table and problem solutions and addresses design aspects of industrial ventilation systems.
