FIELD: measuring engineering.
SUBSTANCE: system comprises device for blowing the object with air jet that has exciter of the air flow delivered, device for sucking air flow from the object provided with the exciter of the sucked air flow, and device for sampling. The blowing device is provided with the swirler of air flow and passage for transporting air flow to be delivered from the exciter to the swirler. The sucking device is made of sucking valve whose outlet is connected with the exciter of sucked air flow. The inlet of the exciter is coaxially mounted inside the swirler. The sampling device is mounted at the inlet of the sucking passage or upstream of it.
EFFECT: enhanced efficiency and reliability.
