A feeder apparatus is provided for delivery of insulation material or the like using pressurized air, particularly where such material is relatively light and fluffy and/or delivered at a low rate. The feeder apparatus includes a hopper and a chute. The hopper receives the material, which is to be carried using the pressurized air. A chute housing a pair of tine assemblies receives the material from the hopper and is used in carrying the material to an inlet. The inlet is formed by first and second adjusting assemblies, which are located on opposite sides of the chute. The user is able to provide a desired size inlet by rotating crank handles of the two adjusting assemblies to cause linear movement of adjustable plates. Material passing from the inlet is received by a rotary pocket feeder having a number of vanes. Pressurized air is also delivered to the rotary pocket feeder. The pressurized air carries the material through an outlet formed in the pocket feeder for delivery to a predetermined site. Pressurized air is vented using air passageways formed adjacent to each of the two adjusting assemblies, which assemblies act to divert such air so that it does not cause unwanted blow back of material. In one embodiment, the material is insulation that is delivered in a fluffy constituency from the outlet to cavities formed in a wall structure of a building.
