Buying advice

Consider the required micron level (5-micron is common), flow rate (SCFM) matching your compressor's output, and whether you need a filter/regulator combo or separate units. Metal bowls are more durable for industrial settings, while transparent bowls allow easy inspection but may be less resistant to pressure and chemicals. For spray painting, a sub-micronic filter (0.01 micron) is essential to remove oil mist.
