FCC-25 explosion-proof dust sampler Introduction: The dust sampler consists of a high-performance suction pump, automatic time control circuit, flow adjustment circuit, automatic feedback constant current circuit, undervoltage protection alarm circuit, safety power supply, etc. It is also equipped with various dust pre collectors. A full dust pre collector used for measuring the total dust concentration; Another type of impact type pre collector used for measuring the concentration of respiratory dust can separate respiratory and non respiratory dust that harm the human body. It can collect both respiratory and non respiratory dust samples at once, and its separation efficiency reaches the "BMRC" curve standard of *. It is a relatively reliable and practical dust pre separation device. This instrument adopts an ibI (150 ℃) grade intrinsically safe explosion-proof structure, and is particularly suitable for use in coal mines and other workplaces containing explosive hazardous gases. The casing of this machine is made of high-strength ABS engineering plastic and has undergone special treatment such as moisture-proof, dustproof, and anti-static measures. The instrument has the advantages of no pulsating airflow, large negative pressure and load capacity, automatic timing sampling, safety and reliability, durability, and convenience for carrying and on-site use. Its main technical indicators have reached or are close to a high level. Technical parameters: Sampling flow rate: 20L/min Suction negative pressure:>3000Pa Load capacity: ≥ 1000Pa Dust collection range: total dust, respirable dust Timing range: Any setting within 0-99 minutes Continuous working time:>120min Working noise: ≤ 70dB (A) Explosion proof form: Intrinsically safe ibI (150 ℃) Applicable environment: temperature -5~35 ℃, relative humidity ≤ 95% RH Overall size: 200 × one hundred and forty × 80mm
