AGA FFM CONVERSION KIT, POS TO NON POS

Convert your Interspiro AGA Full Face Mask from Positive Pressure to Non-Positive Pressure. A common mis-conception is that Public Safety Divers want to go with the positive pressure FFM. They do this to keep contaminated water out of the mask and off the diver's face, but in reality the positive pressure FFM just complicates things by spraying water in the divers face when the mask is being put on or taken off (on the surface). If the positive pressure AGA is inverted it will let water in. In reality all FFMs have positive pressure, however the Pos Press AGA (originally designed for firemen) has a greater positive pressure than other full face masks or the AGA non-positive pressure version.
