Abstract
A particulate detection system () includes detection section (), compressed air source () which includes compressor () for producing compressed air AK, compressor drive circuit () and control means (). The detection section includes a gas jetting source (). A drive condition for jetting air AR from jetting hole (N) at a first flow rate Qis defined as a first drive condition JK, and a drive condition for jetting the air AR at a second flow rate Qsmaller than the first flow rate Qis defined as a second drive condition JK. The control means includes first instruction means Sfor driving the compressor under the first drive condition JKwhen the quantity of the particulates S is detected, and second instruction means Sfor driving the compressor under the second drive condition JKwhen the quantity of the particulates S is not detected.
