Dust extraction for shot blasting machines

Shot Blasting
Dust Collectors

Cartridge and wet dust collectors for shot blasting machines, with configurations also available for sandblasting cabinets and rooms. Selection depends on the workpiece, abrasive, dust load and extraction requirements.

Our shot blasting cartridge systems use a secondary HEPA filter for direct discharge into the workshop, where suitable. Integrated and separate fan arrangements are available for OEM equipment and retrofit projects.

Need More Airflow?

For larger machines, heavier dust loads or several compatible extraction points, consider a modular collector with a separate fan and suitable dust discharge.

Optional Accessories for Cartridge Systems

Spark Arrestor

Where sparks or hot particles enter the extraction duct, an upstream spark arrestor helps reduce their carryover to the filter cartridges. Select it to suit the airflow and process; it supplements the system’s fire protection measures.

Powder Feeder for Oily Dust

For shot blasting oily parts, a duct-mounted powder feeder can introduce compatible conditioning powder to form a protective layer on the cartridges and reduce oil-related clogging. Powder selection and feeding depend on the dust and oil loading.

HEPA Filtration with Direct Indoor Discharge

For suitable applications, filtered air leaves the fan and discharges directly into the workshop. It is not ducted as supply air to individual workstations.

A Practical OEM Package

An indoor discharge arrangement avoids an outdoor exhaust stack for the approved application and simplifies external ductwork. Integrated units suit compact layouts; a separate fan can be placed in an acoustic enclosure.

Maintain the Complete Filtration System

Monitor filter pressure drop, check cartridge and HEPA seals, and service the dust discharge. Pulse cleaning maintains the cartridges; the HEPA stage is replaced when required rather than pulse-cleaned.

Confirm suitability for indoor discharge. Assess the workpiece, abrasive and surface coatings, including hazardous constituents. Verify filtration performance and workplace exposure against project requirements. HEPA captures particles; it does not remove all gases or vapours, and does not itself provide fire or explosion protection.

Wet Dust Collectors for Shot Blasting

Wet collection is an option for selected combustible metal dusts and processes where oily residues or ignition concerns make dry filtration difficult.

Wet Collection for Combustible Metal Dust

For shot blasting aluminium, magnesium-alloy and titanium workpieces, we configure wet dust collectors to suit the metal dust. Our wet collectors for these applications include hydrogen vent valves to help prevent hydrogen accumulation, together with water-level controls and appropriate sludge removal.

Oily Parts and Sludge Handling

Wet collection may be considered for shot blasting heavily oiled cold-rolled steel parts. Check oil loading, dust wettability and the required separation performance. Circulating water still needs maintenance, and sludge and wastewater need an appropriate disposal route.

Outlet treatment and the discharge arrangement are selected to suit the process, including droplet separation and additional filtration where required.

Select Around the Blasting Process

Airflow alone does not define the collector. Start with the blasting machine and dust characteristics, then select filtration, fan pressure and discharge arrangements.

Application	Configuration to Assess	Key Checks
Dry dust; indoor discharge proposed	Cartridge collector + HEPA	Contaminants, filter seals, delivered airflow and verified discharge performance
Limited floor space; one machine	All-in-one cartridge package	Dust load, hopper capacity and maintenance access
Larger airflow or multiple machines	Modular cartridge collector + separate fan	Simultaneous demand, compatible dust streams, duct balancing and dust discharge
Combustible metal or heavily oily dust	Assess a dedicated wet system	Material reactivity, ignition sources, hydrogen, water controls and sludge handling
Sandblasting cabinet or blast room	Collector sized around the enclosure	Openings, nozzle duty, abrasive, visibility, clearance time and operator protection

Capture at the Machine

Use the machine maker’s extraction requirements where available. Check enclosure openings, leakage, duct resistance and dust clearance before doors open. Abrasive recovery and separation remain separate functions from ventilation dust collection.

Also Applicable to Sandblasting

These collector types can also serve sandblasting cabinets and rooms when selected for the process. Provide the enclosure dimensions, openings, nozzle count and abrasive type so we can assess airflow and dust loading. The photos above are shot blasting references; no sandblasting installation is pictured.

Technical reference: OSHA abrasive blasting ventilation guidance. Requirements depend on the installation location and process.

Questions Before Selection

Practical points for OEM packages and dust collection upgrades.

Does indoor discharge mean air is supplied to the operator?

No. In the arrangement described here, air passes through cartridge filtration and the HEPA stage, then the fan discharges it directly into the workshop. There is no dedicated supply-air duct to an operator workstation.

Is HEPA filtration enough to approve indoor discharge?

No. Suitability depends on the dust composition, actual filtration performance, system integrity and applicable workplace requirements. HEPA filtration does not remove all gases or vapours or replace fire and explosion controls.

Can one collector serve several blasting machines?

Yes, where the dust streams are compatible and the system is designed for simultaneous demand. A modular collector, balanced branch ducts, a suitable fan and adequate dust discharge may be required.

When should a wet collector be considered?

Wet collection is an option for shot blasting combustible metal workpieces or heavily oiled parts. Our configurations for combustible metal dust include hydrogen vent valves, with water-level controls and sludge handling matched to the process.

Are the photographs sandblasting projects?

The photographs on this page show shot blasting applications. Sandblasting cabinet and blast-room systems are selected separately according to their enclosure, abrasive and operating conditions.
