IEC VAN DE GRAAFF GENERATOR LARGE 250mm DIAMETER DOME 400kV.
This VDG is now IEC's standard "Large" model Van de Graaff. The 250mm diameter ball is a good size and is in proportion to the rest of the instrument's construction.

It is a modern, compact and robust instrument with easily seen parts and has been specially designed for use in the classroom. It uses an insulating tube to protect the belt and mount the dome.

The pulleys, belt and combs are accessible for inspection, cleaning or adjustment at both the top and bottom ends of the tube.

The belt is made from seamless long lasting silicone rubber ensuring excellent performance and reliability.

The whole instrument can be easily dismantled to reduce size for transport.

Features:
• The belt is extremely easy to change
• Almost indestructible mirror finished 250mm diameter stainless steel dome
• Speed control
• All replacement parts are readily available
• An optional IEC Van de Graaff Accessory Kit is a great add-on set of 7 attachments that fit on the dome

Specifications:
• Output: 400kV under good conditions
• Spark gap: approximately 15cm
• Discharge ball: 80mmD with insulated handle and earth terminal connection
• Charging Belt: 55mm wide seamless silicone rubber
• Belt drive: speed controlled DC electric motor

NOTE: IEC no longer makes the smaller model with the 200mm diameter ball.

NOTE: This is a genuine IEC product.
We believe in supporting Australian industry and only sell genuine IEC products, we do NOT sell imported clones of IEC products.

• Weight: 3.4kg
