BFC-35B Respirable Constant Sampling Rate Dust Sampler

    BFC-35B type respirable dust sampler, is our latest development of total dust and respirable dust sampler dual . Respirable dust sampling head collected dust particle consistent with BMRC curve. Achieve GB16225-1996, GB-16248-1996, GB16238-1996 three countries respirable dust hygiene standards. Dust-laden air that is collected kinetic diameters were 7.07um or less, and an aerodynamic diameter 5um dust collection rate of 50% . Due to the special design of the blade of the pump, the flow is stable, no pulse, accurate measurement.
