Product Description 
 CCZ-20 (A)-type dust sampler for dust operating environment for a short time, the large flow of respirable dust and total dust sampling. The separation efficiency of the dust sampling of respirable dust in full compliance with the "BMRC" international standard curve requires science to reflect the degree of dust exposure to respirable dust quality and workplace dust hazards. 
 The sampler according to enterprise standards of the MT162-95 "workplace dust sampler General technical conditions" and Q/NF-03-2004 dust sampler and GB3836.4-2000 standard the ExibI rating (Intrinsically Safe) explosion-proof design, especially for in the coal mine and the other containing the risk of explosion gases workplace. With sampling airflow pulse is small, large load capacity, flow stability, simple operation, safe and reliable, easy to carry and so on. 
 Technical parameters 
 Sampling flow rate: 20L/min when the respirable dust sampling (fixed); total dust sampling of 25L/min. 
 Fixed sampling flow error: ≤ 2.5% 
 Load capacity: ≥ 1000Pa 
 Mining dust: dust or respirable dust 
 Timing range: 0 to 99 minutes be set to any
