Cartridge Collectors: AT Series Dust Collector
AT Series Advantages
CARTRIDGE AIR CLEANING
Contaminated air is drawn through high-efficiency cartridge filters, where the particulate is collected on the outside of the media. Filtered air is pulled down through the system and
exhausted. Standard units feature Venturi reverse pulse cleaning systems to extend filter life and decrease costs.
HIGH-PERFORMANCE CARTRIDGES
With a 99.7% efficiency rating for submicron (0.5) particulate, extra-large circular filters are vertically oriented for uniform dust loading and efficient cleaning.
EFFICIENCY
The AT Series utilizes a patented downflow/vertical design to ensure consistent filtration and efficient dust handling. Many competitors’ products operate with a high level of
re-entrainment, which means that energy and filter life are wasted by repeated collecting of the same dust.
SIZE AVAILABILITY
The AT Series is designed with a full range of capacities for a vast array of applications. From the AT-2M with (2)
cartridges to the AT-64 with (128) cartridges, every AT Dust Collector has the media capacity and optimal filtering
velocity for every type of contaminant and process.
POWERFUL CLEANING
The patented Venturi assisted design optimizes reverse jet pulse cleaning and increases filter life. With four available methods to initiate the filter cleaning cycle, every AT Dust Collector is equipped with the control system that best fits the application.
IMPROVED FAN OPERATION
Venturi and innovative cylindrical fan housing increases performance, attenuates noise, simplifies maintenance and eliminates the need for a discharge damper.
EASE OF MAINTENANCE
Outstanding design features combine to promote longer filter life. Easy access allows each filter to be changed within
several minutes.
SPACE ECONOMY
The downflow/vertical design has a smaller footprint than comparable units with horizontal filters.
ROCK-SOLID INDUSTRIAL CONSTRUCTION
AT Dust Collectors are built for durability and reliability with 11 gauge steel fabrication and welded seams and joints.

How AT Series Dust Collectors 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 at a steady velocity. Dust is conveyed to the settling area below the
filters by both air flow and gravity. Extremely small
particulate is collected on the filter media, allowing clean air to return to the workplace or outside environment. Once
particulate collection on the filters is sufficient to reduce air flow, the patented reverse jet pulse cleaning system propels the collected dust off of the filters and into the settling area.
DOWNFLOW
The AT Series downflow/verticle design produces zero
velocity at the base of each filter stack, allowing the dust to settle uninhibited below the cartridges, thereby eliminating re-entrainment.
CARTRIDGE FILTERS
The standard 80/20% cellulose/polyester cartridge media is high in resin content to provide mechanical resilience, and has pleat-lock construction. Standard cartridges are rated for temperature up to 160 degrees Fahrenheit. High temperature cartridges are also available.
DUST SETTLING
The AT Series design allows larger dust contaminates to have a clear path to the dust settling area and finer particles 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 compressed air is more equally dispersed across the filter resulting in greater
cleaning effectiveness compared to typical 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 each
application.
CYLINDRICAL FAN HOUSING
The motor, fan and inlet cone are packaged into a tubular
centrifugal fan arrangement for greater performance, quieter
operation and simplified maintenance.
DUST COLLECTION EFFICIENCY
The major obstacle to dust collection efficiency is re-entrainment, the refiltering of dust that has been stirred up prior to settling. The goal is to dislodge the dust from the filter and allow it to settle in the hopper below.
The AT Series utilizes patented downflow/verticle technology to minimize re-entrainment and extend filter life. Carefully
managed inlet air velocity ensures that the air only flows
downward, never upward or sideways. This prevents air
movement below the filters where the dust has settled and results in effective cleaning while the dust collector is operating and shut down.
