Easy control of automatic dampers

The Operation Box is designed to control automatic dampers in fume extraction systems for welding operations and to start/stop the extraction fans (fan contactor needed). The Operation Box consists of a transformer 30VA, a timer for delay variable 0-5 minutes, and two separate connections for sensor clamps. One or two sensor clamps can be connected to the operation box dependent when using one or two different welding machines in the same area. Several operation Box can be connected to each other.

• Reduced installation costs
• Automatic damper closing will save energy on the extraction system
• Adjustable damper delay setting
• 24V AC power supply for working light on extraction arm
