Mediselect 25 O2 UK - DQCKL This regulator has 1x output adjustable from 0 t / m 25l / minute (for nose glasses etc) 1x output DIN (4.5 bar, 65 PSI) with this output you can feed the Care Vent fan. 1x DIN connector with hose clamp is required, this link will have to confirm the end user to the tube of the respirator. (Pipe running from oxygen bottle to fan) As you can see in the picture below there is now another link to the hose, it should therefore be replaced by the DIN plug.
