This air pump is suitable for a number of classroom demonstrations, single barrel made from steel pipe fitted on wooden base. The aluminum plate is provided with a stop cock, air inlet screw and a connection for rubber pressure tubing.

Cat. No.	Description
1)	12.5 cm
2)	15 cm

To demonstrate the pressure of the atmosphere. Two concave aluminum cups having diameter either 62 mm. or 75 mm. Are provided with handle and stop cock.

For showing that pressure is transmitted equally in all directions. It consists of a hollow metal brass ball 5 cm. In diameter with small holes along one circumference and a branch tube with piston. When held with the holes in a horizontal plane and piston is pushed in, water will stream out at the same distance from each hole.

A simple working model to demonstrate the principal of hydraulic press.
