🔍 Key Concepts

• Atomizing sprayer plate numbering conventions (what the digits typically represent) • Relationship between orifice size / number of holes and liquid capacity • How manufacturers group plates in a series (e.g., 29xx vs 30xx vs 43xx)

💭 Think About

• Look at the four codes and ask yourself: which part of the number is most likely linked to flow capacity? The first two digits, the last two, or the letters? • Compare the series (2900, 3000, 4300) and think which series would normally be used for higher-output spraying systems. • Consider whether added letters (like PCRS) usually indicate a special type, pattern, or material, or a change in basic capacity.

✅ Before You Answer

• Identify which part of each code most likely represents size/capacity within that manufacturer’s system. • Confirm that a higher plate capacity would typically correspond to a larger orifice / higher series number rather than just extra letters in the code. • Before picking, mentally rank the four codes from smallest to largest likely capacity based on the numbering pattern, then choose the one at the top of your list.
