What compressor do I need for this kit?

Siphon blasters need continuous airflow at pressure, so a small pancake compressor will struggle. A larger tank and higher cfm output keep the blast steady. Check your compressor's cfm rating against the nozzle you plan to use.

What is the difference between the two orifice sizes?

The 5/64-inch tip gives a finer, more focused blast for detail work. The 1/8-inch tip covers more area faster but draws more air. Start with the smaller tip if your compressor is modest.

Does it come with abrasive?

No. The kit is the gun, pickup tube, 10-foot hose, four nozzle tips and an Allen wrench. You supply the abrasive media separately.

Can it be used with liquids as well as abrasive?

The listing mentions basting liquid or air, but this is a siphon air blaster built for dry abrasive. Treat liquid use as unproven and stick to dry media.

How does it compare with a pressure-pot blaster?

A pressure pot pushes abrasive harder and faster and handles bigger jobs. This siphon kit is lighter, simpler and better for spot work, but it is slower and more sensitive to compressor output.

What media can I run through it?

Fine dry media such as glass bead, aluminum oxide or fine sand suited to the nozzle size. Keep media dry and sifted; damp or coarse grit clogs small siphon tips.
