Scuba Regulators | Scuba Diving Regulators
Today's scuba regulators designs are predominantly open circuit 2-stage scuba diving regulators.
Inside the tank, air is pressurized to about 200 atm. In the 2-stage design, the first stage scuba regulator reduces the air pressure to around 10 atm.
In the second stage, the demand regulator lowers the pressure again to match that of the surroundings. This delivers air at the best pressure to the diver's lungs, in order to counteract the ambient pressure.
Modern air delivery scuba regulators systems provide safe, healthy air to breath with reliable equipment. That's a tribute to the years of dedicated effort and inventiveness of scuba gear designers.
