Improvised Respirator Air Blower / Positive Pressure Test

A quick attempt to make a positive pressure air blower for a respirator, using a computer dust cleaning air blower, I will probably buy a battery powered camping bed inflator and rig that to take a 40mm filter.
However this primitive method makes it very easy to breath in the Siebe Gorman mask designed to work as a SCBA mask.
