Ancillary Items are pieces of equipment that work with the existing equipment. These items can include various pieces of equipment such as: Spark Detection units, Piping and Ductwork, Fans, Blowers, Airlocks, Abort Gates, and Electrical Components, just to name a few.
Spark Detection Units are pieces of equipment that can be configured to detect a spark in the ductwork of a collector and then help suppress the spark before it reaches the filters where a dangerous fire could start. A spark detector can utilize a burst of water or dry chemical to subdue the spark once it is detected.
Piping and Ductwork are used to control where the air flow is directed.
Fans and Blowers help circulate air through a dust collection unit. The primary fan/blower is the heart of the entire system. Fans come in a large variety of configurations. In most cases used fans can be modified to meet precise CFM, static pressure, and horsepower needs. Two very basic fan styles are: material handling fans placed on the positive pressure side of the collector, and centrifugal fans placed on the negative pressure side of the collector. With the latter being the preferred method, that way no material is hitting the fan.
Abort Gates are used to help protect factories and dust collection equipment from sparks, burning material, flammable gases, and smoke. These gates help divert these dangerous products away from the dust collection units.
Rotary Airlocks, as the term implies, create a seal between the collector and the storage component at the bottom of the collector to maintain the pressure inside it. This allows for the material being collected to be removed continuously as not to have to shut down the unit to clean it. The airlock typically uses a slow-moving gear with rubber wipers which move the material into a storage component creating an air tight seal.
