    DIVATOR.mAInTenAnCe.AnD.RepAIR.mAnuAl. 1. InTRODuCTIOn Divator is a self-contained underwater breathing apparatus (SCUBA). The apparatus is designed to suit every category of diver that works under water with air. Environmental factors such as cold, heat, or type of water (chemical compounds, salt or ice) have little or no effect on the operation of the apparatus.
