This company has introduced the Tri-Flow Environmental Control Booth, which was designed for plant areas where dirty and/or noisy tasks need to be confined to their own workspace. The booth provides HEPA-level filtration performance and has a MERV 16 rating. It is 99.999% efficient on particles 0.5 micron and larger by weight. Perforated acoustical panels contain and absorb noise generated inside the booth. It provides reliable and consistent capture velocities at the booth opening and throughout the booth. There is no air turbulence, no "hot spots," and no uncomfortable drafts to interfere with operator productivity. The capture velocity provided throughout the booth means that workers are not confined or tied to a fixed work space, hood, hose, etc. Because the collector pulls in dust through a grille that extends the full width of the booth, workers can freely perform tasks throughout the workspace.products
