Title: Water aerator made of elastic material that can be withdrawn through its retainers to allow replacement in full tank
Inventor: JAEGER ANDREAS
IPC: C02F1/74
Filed: 1999-03-02
Abstract: The aerator is a strip (5) consisting of a heavy rubber base with a thin rubber cover with an airspace between them.
