An apparatus for removing dust from a fiber sample for subsequent analysis is disclosed. A first upper cylindrical chamber containing a fiber sample has a tangential air jet and a radial air jet installed to swirl and tumble the fiber sample in a cyclonic fashion, thus liberating the dust from the sample when either a positive or a negative pressure is applied through the air jets. The liberated dust particles are then screened out through a 100 mesh screen filter and exhausted through a funnel. The device can be equipped with a second stage chamber cont...
An apparatus for removing filter dust particles from fiber for sampling and analysis comprising: (a) a first upper cylindrical chamber having an opening on the bottom end thereof and containing a preconditioned and preweighed fiber sample, said sample containing fiber dust particles to be removed and analyzed; (b) an upper, tangential air jet, located into and through the wall of the first upper cylindrical chamber and periphery tangential to the periphery or inner surface of said first chamber, thus, enabling air to be directed in a tangential manner in...
