refilling fire extinguisher with dry chemical powder 

Thiers small cartridge installed inside cylinder that is pressurizes CO2

You can see in the video the small bottle...that is CO2 bottle connected to the grip, if you push the grip the CO2 automatically release

the cartridges are replaced, they only can be refilled with manufacturers, we only replace for a new and the last cartridge we throw to garbage

Only dry chemical has expiration. The CO2 no expiration as long as no damage .

Hehe testing lng kong marunong

Thankyou for your sharing...

No oxygen but it has CO2 cartridge to blow up the dry chemical inside the cylinder once you press the lever handel.

If you try to refill fire extinguisher make sure the CO2 is empty before you open. If CO2 has pressure and you open it may cause explosion .

@@radneychannel1435 yes sometimes this can occur and you have reason, when we open any extinguisher with cartridge is necessary confirm that this is empty before.

That was an ordinary electrical tape sir

@@radneychannel1435 really? Wow here in México some people say that we have to get the original tape of the manufacturer, but ok, thanks for the tip ✌️
