The Tri-Flow environmental control booth from Tri-Mer Corp. is designed for plant areas where dirty and/or noisy tasks need to be confined to their own workspace. With HEPA-level filtration performance and a MERV 16 rating, the booth is 99.999 percent efficient on particles that are 0.5 micron and larger by weight, the company says. Perforated acoustical panels contain and absorb noise generated inside the booth.
The booths are designed to provide consistent capture velocities at the opening and throughout the booth, with no air turbulence, “hot spots” or uncomfortable drafts to interfere with operator productivity. 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. Typical inlet velocities range from 125 to 150 fpm.
A timer-controlled, automatic pulse-jet cleaning system uses solenoid valves and blow-down pipes to ensure that the booth maintains its capture velocity by measuring filter pressure drop and automatically cleaning the filters on demand. The booths operate at a lower pressure drop than traditional cartridge filters, resulting in lower energy consumption and longer filter life.
The booths are customized to suit the application and the facility, and can be expanded as necessary. It is suited for a variety of metalworking processes, particularly welding, plasma torch cutting, air arcing, sanding, grinding, chipping and buffing. It also is effective for isolating processes such as powder coating, mixing and polishing.
