Poseidon Cyklon 1st Stage Regulator Only

The Poseidon Cyklon Fixed Yoke First Stage is a balanced diaphragm design. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids.
