The ACT Group services, designs and supplies industrial dust collection for Los Angeles County — baghouse and cartridge collector service, replacement filters, dust suppression, ventilation and NFPA 660 compliance for the aggregate, cement, recycling, food and manufacturing plants of the L.A. basin. Crews from Fontana, about an hour out, inside the South Coast AQMD since 1991.
Los Angeles County has some of the densest industrial neighborhoods in the country — Vernon, Commerce, City of Industry, Sun Valley, Irwindale, Carson and the harbor — and every one of them has neighbors, inspectors and a South Coast AQMD permit file. A dust collector that drifts out of compliance in L.A. is not a maintenance item; it is a notice of violation and a community complaint. Since 1991 our crews have kept L.A. collectors performing, and our customers across the basin include Cemex, Granite Construction and Tesla, alongside the recyclers, food processors, foundries and batch plants that fill in between.
Inside the District: We work under South Coast AQMD every day. Rule 403 fugitive dust, permit conditions on collectors, source tests and visible-emission limits — we know what the inspector is looking for because we see it weekly.
About an Hour Out: Fontana to downtown, the San Gabriel Valley and the Gateway Cities is roughly an hour; the ports, South Bay and San Fernando Valley are within two. Filters ride out with the crew.
Any Collector, Any Brand: Donaldson Torit, Camfil, Imperial Systems, UAS, Nederman, RoboVent, MikroPul and the older baghouses that anchor L.A.’s aggregate and cement operations.
Baghouse and cartridge collector service: Change-outs, cage and venturi replacement, leak detection, pulse-system repair, differential-pressure troubleshooting and rebuilds — see baghouse & dust collector servicing.
Dust collection system design and installation: Hood capture, duct sizing, collector and fan selection by the ACGIH method, fabricated in our Fontana shop — start with the free System Designer.
Dust suppression: Fog, spray and foam for truck dumps, crushers, transfer points and stockpiles at aggregate, recycling and port operations — see dust suppression.
Combustible dust and NFPA 660: Dust hazard analysis and explosion protection for food, wood, plastics and metal dusts common in L.A. manufacturing — see explosion protection.
Replacement filters: Cartridges and bags for the major brands, in stock in Fontana — see dust collector replacement filters.

Differential pressure climbing, dust at the stack, or an inspection on the calendar? Call and a crew is moving from Fontana with the filters on the truck.

Vernon to the harbor: collectors kept inside their permits
Los Angeles industrial zones sit shoulder to shoulder with housing, and South Coast AQMD complaint response is fast. A collector that is technically running but drifting on pressure drop, or a transfer point that fogs on a windy afternoon, becomes a violation before it becomes a maintenance ticket. We keep the collector inside its permit and the dust inside the fence.
Cartridges and bags for the collectors we see most across Los Angeles, stocked in Fontana, so a change-out is one visit.
About an hour to downtown, Vernon, Commerce and the San Gabriel Valley from Fontana; up to two to the ports and the San Fernando Valley. Emergency service is same-day and we answer 24/7 at (888) 480-0680.
Yes. We diagnose why the collector or the source failed, fix it, and prepare the engineering data — airflow, pressure drop, control efficiency — you need for your response. We are not attorneys, but we have been through it with many L.A. plants.
Yes. Flour, sugar, starch, wood, plastics and metal dusts are combustible, and NFPA 660 requires a dust hazard analysis and protection on the collector. We perform the analysis and install the isolation, venting and suppression hardware.
We service every major brand and stock Donaldson, Camfil, Imperial Systems, UAS, Nederman/Pneumafil and RoboVent filters in Fontana, with cross-references for the rest.
