What PSI should I run my sandblaster at?
You should use a tank with a minimum of 100 PSI for optimum efficiency with any abrasive sandblasting project. If you work with a lower PSI, you’ll add a significant amount of time to your project. If you reduce your blasting pressure by half, your pressure cleaning project will take four times as long.
Why is my sandblaster not picking up sand?
If your blast gun is not drawing any abrasive, turn off the compressed air supply. Remove the nozzle from the blast gun, inspecting the passageway for any obstructions.
Why does my sandblaster keeps clogging?
Check for a Clogged Nozzle The most common issue with abrasive not coming out of the hose is a clogged nozzle. If debris gets down into your machine and sucked up through the hose it can clog the back of your nozzle. All our hoses have a quick connect to remove the hose from the nozzle effortlessly.
What is the best blast media for rust removal?
If you are blasting aluminum, plastic media, walnut shell, or glass beads are the best choices. These have a lower Mohs hardness, so the metal surface isn’t devastated. For steel or iron, glass beads or aluminum oxide is a good choice, especially if you want to take it down to bare metal.
How big of an air compressor do I need to run a sandblaster?
An air compressor which produces between 10CFM – 20 CFM is ideal for smaller sandblasting tasks. While a compressor which produces between 18CFM to 35 CFM is better for larger jobs where a more powerful experience is needed. While an industrial type of sandblasting needs a CFM of 50 – 100.
What size blast nozzle is normally used?
Nozzle Size For vapor abrasive blasting, the most commonly-used nozzle orifice sizes range from 3/8″ inner diameter to 3/4″, increasing by increments of 1/16″. A 3/8″ nozzle is sufficiently constricted to produce a effective blast pressure with a 185 CFM compressor.
Why does my sandblaster surge?
If you have media flow through the gun, but have intermittent surging (when the media hose fills right up and gradually empties out), or the gun just does not seem to throw enough bead or grit, you need to adjust the vent opening on your pickup tube to balance the mix and produce an even flow.
Can you overfill a sandblaster?
Using blasting material too long will make performance weak and ineffective. Using blast nozzles and orifices too long will make the blast ineffective. Failure to change nozzles and orifices within normal wear times can lead to damage to the blast gun which may lead to the need to purchase an entirely new blast gun.
