What Is Tankless Diving? Understanding Surface Supplied Air Systems and Hookah Diving
A tankless dive system supplies breathing air from a surface compressor through a flexible hose, freeing divers from carrying bulky cylinders and enabling extended dive durations in shallow environments. By connecting a portable compressor or battery-powered pump to a buoyant float, these Surface Supplied Air (SSA) rigs deliver air to regulators worn on some sort of harness at the diver’s body, making hookah diving both accessible and lightweight. This setup promotes convenience, setting the stage for exploring how each component works and what benefits it offers.
How Does a Tankless Dive System Work? Key Components Explained
A tankless dive system consists of three primary parts:
- Surface Compressor or Pump – Provides pressurized air, powered by electric battery or gas.
- Air Hose and Float – Transports airflow while supporting the line on the surface.
- Regulator Assembly – Reduces surface pressure to breathing pressure with a demand valve. Note: BLU3 systems are unique by using patented technology that allows the pump to always operate only at the pressure required for the diver’s depth, thus no pressure reduction is done at the regulator.
By combining these elements, tankless systems maintain a consistent breathing supply without adding cylinder weight, leading naturally into the many benefits this design delivers underwater.
What Are the Benefits of Hookah Diving and Portable Dive Systems?
Hookah diving offers three standout advantages:
