Thermal/Flame Spray Dust and Fume Collectors

The potential for fire and explosion is very real when dealing with Thermal Spray and dust collectors. It is imperative that Farr APC be contacted for proper explosion venting and other safety concerns. Explosion vents, sprinkler kits, flame retardant cartridges and possibly spark traps all need to be addressed during the proposal phase of the sale. With Thermal Spray applications, proper information gathering of the specific application is crucial since there are many different types of processes and material coatings, most all of which will react differently inside the dust collector. Although there are different powders used in plasma spray for example, the process results in generally spherical shaped particulate and consistent in size at around three microns making it fairly easy to capture. With the Farr APC Gold Series Vertical Cartridge Collector, plasma spray and powder applications are generally sized around 1:1 air-to-cloth ratio (A/C) with Hemipleat Fire Retardant cartridges. Electric Arc Wire (EAW) Spray on the other hand has proven to be a real challenge. This dust is very fine (mostly sub-micron) and is inconsistent in shape. This seems to be true of the process itself no matter what type of wire is being used.
