Titan Abrasive Systems ships its Ultrablast portable pressure vessels in three discrete sizes, 300 lb, 600 lb, and 1000 lb, all ASME coded for 150 psi working pressure and built around heavy-duty cast iron abrasive regulators [S2].
Across the US distribution tier, Clemco Industries anchors the catalog for roughly seven of the larger online blast equipment resellers, including SandBlastingMachines.com and JH Norton, with product breadth that spans blast pots, cabinets, rooms, breathing-air systems, and nozzle consumables [S3][S1][S7].
Pressure-vessel capacity tiers and working pressure
Portable blast machines sold in 2026 are sized by media charge, not nozzle count: 300 lb vessels start near $5,995, 600 lb units near $7,695, and 1000 lb units near $10,745 in the Titan catalog, with all three running at 150 psi design pressure and 1-1/4 in piping for up to 50% more airflow than legacy 1 in lines [S2].
Operators needing two simultaneous hoses can order dual-outlet kits, and the pressure-release or pressure-hold control package is typically selected at order entry rather than field-retrofitted, per Titan's published spec sheet [S2].
Catalog breadth across the major US distributors
Blastone publishes one of the deepest online trees: contractor blast pots, mega bulk blasters, internal pipe (ID) systems, robotic/VertiDrive units, track blasters, suction guns, and 15+ nozzle families including angled, high-performance, ID, silenced, and wet-blast variants [S4].
JH Norton Company (Norfolk, VA) extends that catalog with air compressors, dryers, dust collectors, bulk blasters, paint booths, and paint-booth lines from ABS Blast, AirBlast AFC, GFS, and LS Industries, plus soda, dry-ice, sponge, and laser-ablation cleaning as non-abrasive alternatives [S1].
SandBlastingMachines.com and Miles Supply (stone industry) position themselves as single-brand specialists, with SandBlastingMachines.com publishing only Clemco SKUs and price points such as the 1-1/4 in Supa blast hose at $151.25 to $557.88 and the Wetblast FLEX 2448 base unit at $17,333.40 [S3][S6].
Manufacturer vs. distributor split
True OEMs (design + weld + pressure-test the vessel in-house) are a small set: Clemco, Empire, Schmidt/Axxiom (distributed through resellers), Titan, ABS Blast, AirBlast AFC, Trinco/Trinity Tool, and Guyson are the names that recur across IQS Directory listings and the 50-state directory at sandblastequipment.com [S5][S8][S1].
Everything else catalogued under "sand blasting machine suppliers" is typically a regional distributor, system integrator, or blast-room fabricator that sources the ASME pressure vessel from one of the above and adds hoses, valves, lighting, and dust collection around it, a structure reinforced by Blastone's accessory-first category map [S4][S5].
Selection criteria for buyers
Match the vessel capacity to daily media burn rate: a 300 lb pot suits intermittent construction or bridge-spotting work, a 600 lb pot fits two-operator light fab shops, and a 1000 lb pot is the entry point for in-house production lines that must run continuous shifts without refill stops [S2].
For abrasive selection, the major US distributors stock aluminum oxide, garnet, glass, slag, staurolite, steel shot/grit, walnut shell, corn cob, and Armex baking soda, with wet/mist pot options (Blastone MistBlaster) for sites where silica dust or spark control drives the specification [S4][S5].
Safety equipment is non-optional at the order-entry level: every full-system quote from Titan, Clemco, and the Blastone channel includes a Nova 3 / Apollo 600 DLX supplied-air respirator, Radex airline filter, 50 ft breathing-air hose, and double-palm leather gloves as line items [S2][S3].
Criteria-based comparison of leading supplier types
Across the four supplier archetypes a buyer meets in 2026, the trade-offs line up as: pure OEMs (Clemco, Empire, Titan) win on pressure-vessel certification, ASME traceability, and spare-part depth, but are slower on custom blast rooms; catalog distributors (Blastone, JH Norton) win on one-stop access to abrasives, lighting, and PPE, with the trade-off being list price rather than build price; single-brand resellers (SandBlastingMachines.com) win on Clemco-specific technical support and published MSRPs, with the trade-off of zero non-Clemco SKUs; and stone/architectural specialists (Miles Supply) win on automatic sandblast-and-recovery systems for flat stock, with the trade-off of narrower industrial use cases [S3][S4][S1][S6][S7].
Buyers sourcing blast rooms rather than portable pots should treat ABS Blast, AirBlast AFC, Clemco Pre-Designed, and Empire Pre-Engineered as the four sub-line items to compare on footprint, dust collector sizing, and recovery floor type, all of which Norton carries side by side [S1].
Adjacent equipment and spec-first next reads
Foundry buyers who already spec blast pots for cleaning castings also spec sand cooler throughput alongside them, and a 2026 spec map for that selection is laid out in Sand Cooler Suppliers and Manufacturers: 2026 Spec Map for Foundry Buyers. [S1]
For data-center and structural-steel site work, the best sandblasting machine for data center builds: 2026 spec map walks through nozzle-vs-pot sizing for rebar and structural cleanup, while broader machine choices sit in the sand blasting machine and shot blasting machine reference entries.
Trackable signals worth watching: Clemco distributor network refresh (SandBlastingMachines.com and Norton both republish SKU pages within 30 to 60 days of upstream changes), and ASME Section VIII updates that govern the 150 psi design pressure stamped on every Titan-class portable vessel [S2][S3][S1].
