EA-50 Basic Air Table EA-62 Deluxe Air Table

The Air Table is constructed with a flat glass surface that supports the recording and carbon paper. Compressed air is supplied to the pucks through light surgical tubing and exits from the bottom of the puck, causing it to float over the recording paper.

The motion of the pucks is recorded by spark recording. Connection to the spark generator is provided by fine chains running down the air tubes. The spark jumps from a contact in the center of the puck leaving a mark on the recording paper. The Recording Paper is 56 x 56 cm.

Because the pucks have a substantial mass of 550 grams, their motion is undisturbed by the tubing and enclosed spark wire. The spark gap is completely enclosed and cannot be seen or heard during operation. The spark source operates at 10, 15, 20, 30 and 60 Hz when used with 60 Hz line power.

The Basic Air Table comes complete with air compressor, Spark Generator with foot switch, two steel pucks, an air supply with hose, Velcro puck collars, springs, puck weight, edge pulley, suction cup center post, recording paper kit, and complete instruction manual.

The Deluxe Air Table has in addition to the above, an Acrylic Puck, an Aluminum Puck, a pair of Magnetic Pucks, and a Paper Guide.
