OG exemplary drawing
 
1. A reclaim cylinder, comprising:
a housing comprising a first end and a second end and defining a reclaim chamber;
a plurality of gas reclaim ports spaced equidistant from each other and tangentially coupled to the housing such that a centerline of each gas reclaim port intersects an exterior surface of the housing at an angle of about 45 degrees or less;
a gas sampling port perpendicularly coupled to the housing such that a centerline of the gas sampling port intersects the exterior surface of the housing at an angle of about 90 degrees; and
a particle sampling port perpendicularly coupled to the housing such that a centerline of the particle sampling port intersects the exterior surface of the housing at an angle of about 90 degrees;
wherein the reclaim cylinder is configured to be coupled to a fiber draw furnace system; and
wherein a cross-sectional area of a gas flow passage within the reclaim cylinder is uniform along a length of the housing defined by the first end and the second end.
