Tri-Mer Corporation, a provider of air pollution control systems and indoor air quality products, has introduced the Tri-Flow Environmental Control Booth, which is designed for plant areas where dirty and/ or noisy tasks need to be confined to their own workspace. The solution is applicable to mining equipment OEMs, rebuilders and mine maintenance shops as it is aimed at metalworking areas, particularly welding, plasma torch cutting, air arcing, sanding, grinding, chipping, and buffing. It is also described as highly effective for isolating processes such as powder coating, mixing and polishing.
The Tri-Flow Environmental Control Booth provides HEPA level filtration performance and has a MERV 16 rating. It is 99.999% efficient on particles of 0.5 micron and larger by weight. Perforated acoustical panels contain and absorb noise generated inside the booth. The company states that Tri-Flow Environmental Booths provide 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 or hose. 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 are generally in the range of 125-150 feet per minute (FPM). Tri-Flow Booths also operate at a significantly lower pressure drop than traditional cartridge filters. This results in significantly lower energy consumption as well as longer filter life. Typically, Tri-Flow filters have a productive service life three to five times that of conventional filters. The Tri-Flow booths use low-speed, low-noise direct drive blowers that are an integral part of the booth and power module. A timer-controlled, automatic pulse jet cleaning system uses solenoid valves and blow-down pipes to assure that the booth maintains its capture velocity by measuring filter pressure drop and automatically cleaning the filters on demand. Filter access is easy, and change-out is simple and tool-free, according to Tri-Mer.
The booths feature a smooth, ledge-free interior to minimise dust accumulation. Each booth is custom-configured to suit the application, and can be expanded as facility needs change. Overhead lighting is provided to suit the application as well. Tri-Mer also states that the Tri-Flow Booth is also the only environmental booth that is customised to the facility. A selection of seven media options provides a solution for most applications, whether it involves electrostatics, fine dusts or fumes, high temperatures, or hydrophobic/oleophobic particulates. All media is pleated and continuously bonded for maximum stability.
