How Downflow/Vertical Systems Operate

How Downflow/Vertical Systems Operate

Contaminated air enters the collector above the filter cartridges. Specially designed components in the cabinet uniformly distribute the contaminated air across the top of the filters. The contaminated air flows downward without the detrimental velocity spikes that are common with competitive designs. Dust is conveyed to the settling area below the filters by both air movement and gravity. The extremely small particulate is collected on the filter media, allowing clean air to return to the workplace. Once particulate collection is sufficient to reduce airflow, the patented reverse jet pulse cleaning system is initiated to propel the collected dust off the filters and into the settling area.

Downflow

Air Boss’ downflow/vertical design has zero velocity at the base of each filter stack, allowing dust to settle uninhibited below the cartridges, thereby eliminating re-entrainment.

Cartridge Filters

The standard 100% cellulose cartridge media is high in resin content for mechanical resilience and has pleat-lock construction. Standard cartridges are rated for temperatures up to 160° F – high temperature cartiridges are available.

Dust Settling

The Air Boss design allows larger dust contaminants to have a clear path to the settling area and finer dust to be collected by the filters.

Venturi

Venturi Reverse Pulse Cleaning is the quick release of pressure through a blowtube into a venturi enductor tube into a cartridge filter. A higher volume of air is induced via this principle. The resulting burst of com- pressed air is more equally dispersed across the filter resulting in greater cleaning effectiveness compared to standard reverse pulse cleaning.

Pulse Jets

Pulse jet performance and economy are maximized by optimizing the orifice size and position. There are four methods of initiating jet pulse cleaning to best fit the end user’s needs.

Cylindrical Fan Housing

The motor, fan and full-length venturi are packaged into a tubular centrifugal fan arrangement for greater performance, quieter operation and simplified maintenance.

Solution. With Air Boss’ patented downflow/vertical airflow technology, re-entrainment and its effects have been minimized for maximum efficiency and filter life. Carefully managed inlet velocity ensures that the air only flows downward, never up or sideways. This prevents air movement below the cartridges, where the dust has settled, and facilitates effective cleaning, both when the collector is operating and when it is shut down.
