Thermal Spray Dust Collectors and Metalizing Dust Collection Systems

All thermal spray processes create overspray that can create hazards. Whether using plasma, HVOF, arc, or flame spray, fine metal particulates endanger worker/operator health, trigger NFPA 652 combustible dust risks, and can violate OSHA exposure limits for nickel, chromium, zinc, and cobalt.

The right thermal spray dust collectors turn that risk into a controlled, repeatable part of your operation. Astro Alloys supplies purpose-built metalizing dust collection equipment engineered to capture submicron metal particulates at the source, protect operators, and keep your spray cell running without interruption.

Built for the Demands of Thermal Spray Environments

Standard shop-floor units are not designed for the fine, reactive, and often pyrophoric dust generated by metalizing. Astro Alloys offers high-performance CamFil Farr dust collectors, the same systems trusted by aerospace, oil and gas, and medical device manufacturers running 24/7 production. These compact, energy-efficient units handle the heavy particulate loads of thermal spray booths while maintaining the airflow needed to prevent re-entrainment onto coated parts.

Core capabilities include:

  • HemiPleat filter cartridge technology with fire-retardant media sized at a conservative air-to-cloth ratio for thermal spray duty
  • Sub-micron filtration efficiency on fine metal dusts, including chromium, nickel, zinc, bronze, aluminum, and carbide overspray
  • Explosion protection options, including vents, spark traps, and flame-retardant cartridges aligned with NFPA requirements
  • Modular designs that fit tight spray cell footprints and integrate with existing ductwork

Application-Specific Dust Collection for Thermal Spray Processes

Not every spray process produces the same dust. A dust collection for thermal spray system sized for arc spray zinc will not perform correctly on a tungsten carbide HVOF cell. Astro Alloys evaluates your application, material, and cycle time to recommend the right configuration.

  • Plasma spray: High particulate loading with very fine ceramic and metallic powders. Requires high-efficiency cartridge filtration and stable negative pressure to protect coating quality on plasma and arc spray equipment.
  • HVOF: Dense, high-velocity overspray with tungsten carbide, chromium carbide, and superalloy powders. Benefits from robust airflow capacity and abrasion-resistant ducting to match the demands of HVOF spray and coating equipment.
  • Arc spray and metalizing: High volumes of zinc, aluminum, and copper alloy dust, often combustible. Pairs with arc spray systems and requires spark detection and deflagration protection.
  • Grit blasting and surface prep: Heavy, abrasive dust loads that benefit from pre-separators and heavy-duty cartridge media.

Compliance, Safety, and Uptime

For EHS managers and plant engineers, an Industrial Dust Collection System is not just an air-quality investment, it is also a compliance tool. A correctly engineered system helps you meet OSHA PELs for hex chrome and other regulated metals, satisfies NFPA 652 dust hazard analysis requirements, and reduces the explosion risk that comes with accumulated combustible metal dust. It also cuts housekeeping labor, extends the life of booth windows and manipulators, and protects expensive coating equipment from contamination.

Metal finishing dust collection is equally critical in industries where coating integrity defines the product. Astro Alloys supports aerospace, oil and gas, medical, power generation, and other industries served with dust collection solutions matched to their specific regulatory and production demands. Pair your spray cell with a thermal spray acoustical enclosure to control dust, reduce noise to 85 dBA, and deliver consistent quality coatings shift after shift.
