Behind Closed Doors

Lang Technovation’s Clean-Tec fan clears away chips and coolant inside enclosed machining centers.

Available from Big Kaiser, Lang Technovation’s Clean-Tec fan is an alternative to compressed air guns for removing debris from workpieces within enclosed machining centers. Unlike handheld air guns, the fan runs with the machine doors closed, protecting the operator from sprays of coolant or metal chips. And, because the fan operation is included in production programs, it’s a viable option for unattended or lights-out production.

The fan is constructed of a fiberglass compound with a steel center core and can be fitted into 20-mm or 3/4" diameter commercial shanks. Its fiberglass wings open when the spindle is turned on and collapse when it stops for easier storage, as shown in the video above.
