Built-In Air Systems

Tankless diving, built into your boat Flip a switch. Get in the water. The BIAS Tankless Dive Module places Brownie’s proven surface-supplied air system below deck—ready whenever the water calls, without scuba tanks or a floating compressor taking over your boat. Complete 2-diver basic kit Up to 3 divers 24V variable-speed power Optional battery module Optional 140 ft E-Reel Build your BIAS The heart of every BIASThe actual 24V variable-speed compressor module—shown without the optional battery module. A cleaner way to equip a dive boat Keep the deck open and the water within reach BIAS turns tankless diving into part of the boat. The compressor stays mounted in a protected, properly ventilated location while quick-release air connections make it easy to rig the system when it is time to dive. 01 Hidden below deck Move the compressor off the swim platform and out of the way of everyday boating. 02 Push-button operation Electric power means no gasoline, pull cord or exhaust at the surface. 03 Built around your boat Choose your power source and add the E-Reel when integrated hose storage matters. 04 Ready for a dive buddy Every configuration begins as a complete two-diver basic package. Integrated into the vesselKeep the working system out of the way while preserving quick access for dive days. Choose two or three diversSelect the complete basic diver package that matches your crew. One module. Three simple selections. Choose divers, power and hose management Every combination starts with the same BIAS Tankless Dive Module. Choose equipment for two or three divers, decide whether to add the dedicated battery module, and select manual hose storage or the powered E-Reel.

Configure the boat-side system Match the system to your vessel Power Use your power or add ours The dive module operates on 24V DC. Choose the dedicated battery module for a matched onboard energy source and built-in charging from the boat’s 12V system. Without battery moduleBest when the vessel already has an appropriate 24V source planned for the system. With battery moduleIncludes the dedicated RELiON power module on its own StarBoard base. Hose management Keep it simple or reel it in The optional E-Reel gives the hose a permanent home and powered retrieval, helping keep a finished installation clean and fast to deploy. Without E-ReelUse the basic hose setup and stow it manually after the dive. With E-ReelAdds a 140 ft hose, quick disconnect, stainless hawse fitting and rocker switch. Optional powered hose management Deploy the hose. Reel it back in. The E-Reel turns the diver hose into part of the boat’s finished installation. A rocker switch powers retrieval while the stainless-steel hawse provides a clean route through the hull or cabinetry. 140 ft hose includedProvides the working length for the BIAS diver setup. Powered retrievalBring the hose back aboard without manually coiling the full length. Installation-ready componentsIncludes the reel assembly, quick disconnect, stainless hawse fitting and rocker switch.

Add One to Cart A backup that travels with the diver Why consider Spare Air? The BIAS supplies breathing air from the boat through the diver hose. Spare Air gives the diver a separate, compact breathing source that does not depend on the compressor, boat power or surface hose. Independent from the BIAS and its hose Compact 3 cu. ft. refillable cylinder Designed for emergency use—not as a primary dive-air source Available per diver, so each person can be equipped consistently Spare Air does not replace training, conservative dive planning or the need to remain prepared to make an emergency ascent. Divers must use an appropriate, secure carry method and follow the current manufacturer instructions. Explore the 3 cu. ft. package Plan the installation New build, refit or a “new to you” boat A good BIAS installation starts with a dry, ventilated equipment location and a clear plan for power, clean air intake and hose access. Secure mounting The compressor module is supplied on a King StarBoard base with pre-drilled mounting holes. It must be securely fastened before operation. Clean breathing-air source The installation area must be dry and well ventilated. If breathable air is not available at the compressor location, plan a fresh-air intake to a clean source. Power planning Confirm conductor size, run length, circuit protection and charging arrangements with a qualified marine installer before installation. Project support Contact Brownie’s before finalizing the installation when you need foundation drawings or guidance coordinating the system with a boat builder or yard. Preparation matters Train, plan and be ready Breathing underwater involves inherent risk. Proper instruction, installation, maintenance, dive planning and emergency preparation are essential. Get properly trained Training access codes are included with the product. Divers can complete Brownie’s online training and receive completion certificates before using the system. Divers should follow the current Brownie’s instructions, stay within the limits of their training, experience and equipment, and remain prepared to make an emergency ascent. Explore Brownie’s online training → Consider independent backup air For dives beyond a depth at which a diver is personally comfortable making a controlled free-swimming ascent, many experienced divers carry an independent emergency breathing source. Backup equipment does not replace training or proper dive planning.
