Manual Fan Control

This unit includes the operation box, the fan contactor for the 3-phase motor, transformer, & overload protection.
Less heated air is extracted to outside, and less electricity consumed if the Fan operates only while work is in progress. Switch the Fan on/off manually at the hood, or automatically with a sensor clamp. Single-phase power supply to the operation box. The automatic Fan control has a sensor clamp to be attached to the earth cable of the welding set for automatic start-up of the fan. Detects currents from 8 A. The operation box consists of a 30 VA transformer for the lighting kit in the extraction arm, a delay timer for fan stop variable from 0-5 minutes, and two separate connections for sensor clamps.
