Industrial Cartridge Dust Collector

A.C.T. Dust Collectors — Downward-Airflow Cartridge Collection

Most cartridge dust collectors mount their filters vertically, with dirty air entering from the side or below. When the pulse-cleaning cycle fires and dislodges accumulated dust, that dust has to travel against the airflow to reach the hopper and much of it gets re-entrained on the filters before it gets there. A.C.T. Dust Collectors are built around a different principle. Dirty air enters from the top of the housing and flows downward through horizontal cartridge filters. When the pulse-clean cycle fires, dislodged dust falls with the airflow directly into the hopper. The result is longer filter life, lower pressure drop over time, and less maintenance. ACT’s standard Nano-Elite nanofiber cartridges deliver 99.9% filtration efficiency at MERV 15, and because they use standard 254 sq ft cartridges, filter replacement costs stay predictable. As an authorized ACT distributor, we size systems from single-source weld cells to centralized factory extraction serving an entire production floor. ACT is designed, engineered, and manufactured in the USA.

• Airflow Range: 1,000 CFM to 100,000+ CFM; modular expansion available
• Standard Filter Media: ACT Nano-Elite nanofiber — 254 sq ft per cartridge, MERV 15, 99.9% efficiency
• Cleaning System: Venturi-assisted pulse-jet — Goyen® diaphragm valves, Dwyer solid-state controls
• Airflow Design: Top-entry downward flow — dust falls into hopper; eliminates re-entrainment
• Door Design: Patented single-handle cartridge access — no tools, no knobs, no springs
• Accessories: Spark arrestors, explosion venting panels, hopper discharge options
• Made in USA: Designed, engineered, and manufactured domestically

ACT Series — Size-by-Size Performance

ACT models are designated by Series (housing size) and cartridge count. All use identical 254 sq ft Nano-Elite cartridges, so filter area scales directly with cartridge count.

ACT Model	Cartridges	Filter Area	Airflow	Typical Application
ACT 2-4	4	1,016 sq ft	~2,000 CFM	Single weld cell, small grinding station
ACT 2-8	8	2,032 sq ft	~4,000 CFM	2–3 weld cells, laser table, plasma cutting
ACT 3-12	12	3,048 sq ft	~5,800 CFM	Multiple weld stations, grinding, blasting
ACT 3-24	24	6,096 sq ft	~10,400 CFM	Production welding lines, thermal spray, powder coating
ACT 4-16	16	4,064 sq ft	~8,600 CFM	Fabrication shops, heavy grind, blasting booths
ACT 4-80	80	20,320 sq ft	~40,000 CFM	Central plant extraction, large fabrication facilities
ACT 4-112	112	28,448 sq ft	~55,000+ CFM	Multi-process centralized systems, automotive, aerospace
