How does the vacuum recovery system work?

The unit features a 1200W vacuum motor that sucks up the used media and dust through the brush head while you blast. It captures up to 90% of the abrasive, which is then filtered and dropped back into the recovery area for reuse.

Why is the sand flow pulsing or clogging?

This is usually caused by moisture. If the air from your compressor is damp, the sand will clump. Ensure you drain the built-in water trap frequently. Using an additional air dryer for your compressor is highly recommended in humid climates.

Can this unit be used for delicate surfaces like wood or thin sheet metal?

Yes, but you must adjust the PSI (pressure) and choose the correct media. For wood, use lower pressure and walnut shells; for heavy rust on thick steel, increase the PSI and use aluminum oxide.

Product Q&A

Q:What's the delivery time?

5-10 work days after receiving client's payment

Q:What's package?

wooden box packaging

Q:What's the payment method?

T/T, WESTERN UNION, MONEY GRAM,LC...

Q:What size air compressor do I need for this 28-gallon unit?

To ensure continuous and powerful blasting, we recommend a compressor with at least 5 HP that can deliver 10-20 CFM at 60-125 PSI. Small "pancake" or DIY compressors may only allow for short bursts of work.

Q:Can I use regular sand from the hardware store?

No. We strongly recommend using professional abrasives like glass beads, aluminum oxide, or walnut shells. Regular play sand contains silica (health hazard) and moisture, which will cause the machine to clog and the tank to rust.
