Screw Conveyors

Add on to an existing screw conveyor or keep it running like new.

Screws

Screws are designed for right-hand operation. Screws with a thicker edge offer longer service life for abrasive materials.

Mobile Small Parts Bulk Dispensers with Vacuum Port

Insert the wand of your vacuum conveyor in the port to move material out of these bins. They have casters, so they’re easy to wheel where needed.

Stackable—Stackable bins are molded so you can stack up to three bins high.

Air-Powered Vacuum Conveyors for Hose

Air powers these vacuums to create a powerful inline conveyor that moves small parts, shavings, and bulk solids. A small amount of compressed air at the inlet produces a vacuum at one end and a high-output flow at the other. Vacuums have no moving parts and require minimal maintenance. A complete conveying system requires a vacuum plus a filter/regulator (to control flow), duct hose, and air hose (all sold separately). For filters and regulators, the max. scfm rating at 80 psi should be equal to or greater than the air consumption of the vacuum.

Aluminum—Aluminum vacuums are lightweight and corrosion resistant.

Steel—Steel vacuums are more durable than aluminum so they're better for larger, more abrasive objects such as steel shot and glass beads.

Stainless Steel—Stainless steel vacuums are more durable than aluminum so they're better for larger, more abrasive objects such as steel shot and glass beads. Stainless steel is the most corrosion resistant.

Air-Powered Vacuum Conveyors for Threaded Pipe

Air powers these vacuums to create a powerful inline conveyor that moves small parts, shavings, and bulk solids. A small amount of compressed air at the inlet produces a vacuum at one end and a high-output flow at the other. Vacuums have no moving parts and require minimal maintenance. A complete conveying system requires a vacuum plus a filter/regulator (to control flow), pipe, and air hose (all sold separately). For filters and regulators, the max. scfm rating at 80 psi should be equal to or greater than the air consumption of the vacuum.

Aluminum—Aluminum vacuums are lightweight and corrosion resistant.

Steel—Steel vacuums are more durable than aluminum so they're better for larger, more abrasive objects such as steel shot and glass beads.
