This is a small reciprocating air pump used for various tasks including aerating Koi ponds and providing modest volume air at low pressure continuously. It uses an electromagnet to move a spring loaded piston with a close tolerance ceramic coating, so that no physical seal or wet lubricant is needed on the piston itself. This makes it very easy to move at low power.
This particular pump is one of the smallest at 25W and 45 Litres of air per minute, but others are available with higher ratings up to about 275Lpm from what I can see online.
