Application
Highlighted use-cases so you can quickly match the machine to your job.
The sand blasting hopper P7-500 is built for field jobs where the workpiece can't be moved - structural steel, pipelines, tanks, and heavy fabricated components. Compressed air supply (113 CFM at 80 psi), not machine placement, is the main constraint on where it can work.
Removes mill scale and surface rust from structural members on-site at the erection stage, so primer and paint bond properly without a separate shop-blasting step.
Prepares pipeline joints and storage tank surfaces ahead of protective coating application, working directly at the installation site rather than requiring the section to be moved to a shop.
Strips corrosion from fabricated parts too large or heavy to move into an enclosed cabinet, restoring a clean base metal surface before coating or further processing.
Cleans weld joints on assembled structures to a uniform surface profile, which coatings need in order to adhere evenly across the joint and the surrounding base metal.
Removes old coatings and corrosion from in-service steel structures and plant equipment during scheduled maintenance, preparing the surface for recoating without dismantling the structure.

Product details
The sand blasting hopper P7-500 is a medium-capacity, manually operated sand blaster hopper built for contractors who need more throughput than a light-duty portable sand blasting machine but don't yet need a remote-controlled system. It's part of our contractor series - sized for field mobility without sacrificing pot capacity.
Sand blasting hopper price is driven mainly by two factors: the blasting pot's capacity and the cleaning rate it can sustain per hour. Larger pots and higher cleaning rates cost more because they need heavier-gauge tanks, larger valves, and higher air consumption to match.
Beyond capacity, price is also shaped by:
Why the P7-500 costs more than a light-duty portable machine: its 500 kg metallic pot capacity and 9-12 sq. m/hr cleaning rate put it in the contractor-grade tier - built for daily field use rather than occasional light jobs, which means heavier construction throughout.
A sandblasting hopper P7 500 (also called a medium-capacity sand blasting machine) is named for the volume of abrasive it stores in its blasting pot, combined with easy portability for on-site work. The P7-500 is operated manually - the operator adjusts the pot pressure directly as it rises or falls during blasting, rather than through a remote control.
This manual-control design is what keeps the P7-500 cheaper than remote-controller machines of similar capacity, while still delivering a moderate 9-12 sq. m/hr cleaning rate suitable for regular contractor use.
The blasting hopper P7 500 can work with different abrasive media to meet specific cleaning and surface preparation needs. Choose garnet, aluminium oxide, steel grit, steel shot, glass beads, or copper slag according to the material, coating thickness, required surface profile, and desired finish. The correct abrasive improves blasting efficiency, reduces media consumption, and helps achieve consistent surface results.
Choose the P7-500 if you need daily contractor-grade output (9-12 sq. m/hr), want to control pressure manually to keep upfront cost down, and work with structural steel, pipelines, tanks, or fabrication jobs too large to move into a sand blasting cabinet.
Consider a different model if you need higher throughput and are willing to pay more for remote pressure control, or if your components are small enough to blast in an enclosed cabinet - that setup gives you better abrasive recovery and dust control at lower running cost per part.

The price depends on current material costs, order quantity, and any customization - request a quote with your location for an exact figure.
Approximately 9-12 sq. m/hr under guidance conditions; the actual rate varies with abrasive type, nozzle size, and surface condition.
113 CFM at 80 psi. Confirm your compressor meets this requirement before ordering, since an undersized air supply reduces the cleaning rate.
Manually controlled - the operator adjusts pot pressure directly, which keeps the machine's cost lower than remote-controlled equivalents.
Pot capacity, cleaning rate, control type (manual vs. remote), and manufacturing scale all affect price - mass-produced models are typically priced lower than small-batch equivalents with the same specs.
