Abstract

Dispensing equipment for dispensing blown loose-fill insulation. The equipment includes a flexible delivery conduit that conveys loose-fill insulation material from a source of such material and, possibly, an optional a rigid tubular wand connected to the distal end of the conduit. The equipment further includes an insert projecting radially inwardly into the loose-fill insulation flow path of the delivery conduit and/or wand for mechanically separating the insulation material's fibers and particles prior to discharge from the delivery conduit or wand. The insulation material separating structure conditions or “opens” the insulation material in such a way that the material is discharged in a substantially uniform density stream of substantially uniformly distributed fibers and particles.
