Portable Sand Blasting Machines, P7300

The portable sand blasting machines P7-300 are semi-medium-capacity portable sandblasting machines built for contractors who need a model light enough to move between sites but with more tank capacity than an entry-level unit. It's manually controlled - the operator switches the blasting pot on and off directly at the knob - which keeps the machine simpler and more affordable than a remote-controlled equivalent.

What Is the Portable Blasting Machine P7-300?

The P7-300 is a portable sand blasting hopper - a pressurized blasting pot mounted for easy movement between job sites, sized to hold 300 kg of abrasive. Like the sand blasting machine, it works by forcing abrasive media across a surface at high velocity using compressed air, giving an even finish that reaches corners and crevices a hand tool can't clean as consistently.

Being manually operated means the operator adjusts pot pressure at the machine itself rather than through a handheld remote - this is the main functional difference between the P7-300 and its remote-controlled sibling, the P7-300R.

How the P7-300 Portable Sand Blasting Equipment Works?

• Abrasive media (25-80 mesh) is loaded into the 300 kg tank.
• The operator manually opens the pot's control knob to pressurize the tank with compressed air.
• Pressurized air forces abrasive from the tank into the 5-metre blast hose.
• The abrasive-air mixture passes through the mixing tube and out through the sand blasting nozzle.
• The operator directs the nozzle at the work surface, and impact strips paint, rust, scale, or contamination.
• The automatic exhaust valve releases pressure when the operator closes the knob, allowing safe refilling or shutdown.

Because control is manual rather than remote, the operator manages pressure directly at the machine - there's no handheld unit to start or stop the blast from the nozzle end, which is the main functional difference versus the P7-300R.

Key Features of 300 kg Portable Sand Blasting Machine

• 300 kg portable sand blasting machines abrasive tank capacity (85-litre volume): sized for semi-medium jobs without the bulk of a larger contractor model.
• Manual pressure control:  straightforward on/off operation at the machine, no remote electronics to maintain or fail in the field.
• Stainless steel construction: resists corrosion under repeated abrasive exposure and outdoor site conditions.
• 5-metre blast hose: enough reach for most on-site jobs without needing the operator to relocate the portable sand blasting machine constantly.
• 25-80 mesh abrasive compatibility: works with a range of common abrasive media sizes.
• 5-9 sq. m/hr cleaning rate (guidance only): moderate throughput suited to contractor and workshop use.
• 85 CFM air requirement at 80 psi: moderate compressor demand compared to higher-capacity models.
• Included accessories: air filter, automatic exhaust valve, and mixing tube ship with the machine rather than being sold separately.
• Lightweight, portable design: built to move easily between job sites, not fixed to one location.

Is the Portable Sand Blasting Machine P7-300 the Right Model for You?

Choose the P7-300 if you need a lightweight, easy-to-move machine with more capacity than an entry-level unit, and manual pressure control keeps your job simple enough that you don't need a handheld remote.

Consider the P7-300R instead if you want remote on/off control from the nozzle end of the hose - useful for jobs with frequent start-stop cycles or a single-operator crew.

Consider the sand blasting hopper P7-500 instead if you need a higher cleaning rate (9-12 sq. m/hr) and larger tank capacity for heavier daily contractor use.

Why Buy the Portable Sand Blasting Machines P7-300 From Airo Shot Blast Equipments?

We've manufactured P7 300 portable sand blasting machines in India since 2008 - 18 years, 8,000+ units installed, 25+ countries served. We are also a supplier of abrasive blasting machines, including sand blasting hopper P7 150, shot blasting machine, grit blasting machine, sand blasting cabinet, suction blasting cabinet, wet blasting machine, wheel blasting machine, dustless blasting machine, granite engraving machine, dust collector, air compressor, abrasive media, thermal spray gun, zinc spray gun, thermal spray wire, etc. On a contractor-grade model like the P7-300, that shows up in a few concrete ways:

• Stainless steel construction for corrosion resistance under repeated abrasive exposure.
• Included accessories (air filter, automatic exhaust valve, remote control valve, mixing tube) rather than sold separately - fewer things to source before you can start work.
• ISO-certified manufacturing with export documentation handled in-house for international orders.
• Direct engineering support for confirming your compressor meets the 85 CFM @ 80 psi requirement before you order.
