At Davy Jones Locker, Koh Tao, we have recently upgraded our compressor system. In addition to our existing Coltri Sub MCH 16 compressor we now have a new Bauer Poseidon compressor. This increases the speed we can pump air fills to 400 liters per minute. We also have a new Bauer B-Kool unit, this is designed to add a second stage of cooling and drying to the air we compress. Breathing grade air is required to pass through a filter cartridge, which contains special granules to clean and dry the air. This prevents bad tastes, smells, oil and water from entering your scuba cylinder. With the B-Kool unit the filter performance is improved by seven times. After filtration the air is now deliver to our new five way manifold allowing us to fill up to 5 tanks at the same time.
