AYO WX Gas Filter Unit Inlet Cover

The Gas Filter Unit Inlet Cover is a silicone piece containing a rectangular tray-like cover that can be air-tightly fitted to the bottom of the Gas Filter Unit, and a round plug that can be fitted to the outlet of the Gas Filter when it is detached from the Power Unit.
The Cover also has a link portion designed to connect to the Guard Link in a default use case where the Gas Filter Unit is connected to the Power Unit. In this case, the round plug is not used.
The Cover can also be used standalone with a Gas Filter Unit; in this case, the round plug fits into the gas cartridge outlet, and the link portion is not used.
The Gas Filter Unit Inlet Cover provides a convenient way to prevent ambient air from consuming the activated carbon inside the gas cartridge when not in use.
