Tri-Mer releases environmental control booths with HEPA level filter performance


Tri-Mer, Owosso, Mich., has released the Tri-Flow Environmental Control Booth that was designed to meet the five specific requirements buyers say are most important for an environmental enclosure in an industrial setting: protection from dust and noise, efficient filter performance, simple operation and maintenance, booth design flexibility, and low life cycle cost.

1) Protection from dust and noise
The Tri-Flow Environmental Booth was designed for plant areas where dirty and/ or noisy tasks need to be confined to their own workspace. The Tri-Flow Environmental Control 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.

2) Efficient filter performance
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, 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. Typical inlet velocities are generally in the range of 125-150 FPM.

Tri-Flow Booths 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 3 to 5 times that of conventional filters.

3) Simple operation and maintenance
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."

4) Booth design flexibility

Tri-Flow booths feature a smooth, ledge-free interior to minimize 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.

The Tri-Flow Booth is also the only environmental booth that is customized to the facility. A selection of 7 media options means there's an ideal solution for your application, whether it involves electrostatics, fine dusts or fumes, high temperatures, or hydrophobic / oleophobic particulate. All media is pleated and continuously bonded for maximum stability.

5) Low life cycle cost
The Tri-Flow Environmental Booth provides manufacturing, process and job shop facilities with an exceptionally efficient, new option for in-plant enclosures. It is the ideal choice for companies who want to combine high filter efficiency – 99.999% on 0.5 micron and larger particles (by weight) – with lowest life cycle cost.

The Tri-Flow Environmental Booth is useful for metalworking processes, particularly welding, plasma torch cutting, air arcing, sanding, grinding, chipping, and buffing. It is also highly effective for isolating processes such as powder coating, mixing, and polishing.
