Decompression Pump

The Decompression Pump is a hand-operated pump used to remove air from a compatible plastic bottle, creating a partial vacuum for classroom demonstrations of atmospheric pressure. Repeatedly moving the handle helps students observe the effects of reducing the air pressure inside a container.

Key Features

• Manual pump for creating a partial vacuum in a compatible plastic bottle
• Simple push-and-pull operation
• Useful for school physics investigations of air pressure and pressure differences
• Made from ABS resin

Educational Applications

• Explore how air pressure changes when air is removed from a container
• Investigate pressure differences between the inside and outside of a bottle
• Use alongside other atmospheric pressure demonstrations, such as the Rubber Mat Air Pressure Demonstration (45RM)

Specifications

• Dimensions: 120 × 75 mm
• Material: ABS resin
• Compatible bottle opening internal diameter: 18–20 mm

Note

Use only with a suitable compatible plastic bottle. Bottle not included.
