HBB200 Delta B.I.B.S MK II

Lightweight built-in breathing system for hyperbaric chambers.

The Delta MK II BIBS (Built-In Breathing System) provides low work of breathing for therapeutic and emergency use within hyperbaric chambers.

The unit combines a durable advanced polymer body with a removable oro-nasal assembly for individual issue, hygienic change-out and biological decontamination.

Associated supply and exhaust equipment includes pressure regulators, manifold blocks and quick-connect fittings, available separately.

Technical Specifications

Model: HBB200
Weight: 1,010 g
Operating depth: 450 msw
Work of breathing: Low, assessed using NORSOK U101 guidelines
Cleaning: Cleaned and prepared for oxygen use

Performance & Testing

The Delta MK II has been independently tested to 450 msw. At a respiratory minute volume (RMV) of 62.5 litres per minute, work of breathing, carbon dioxide levels and respiratory pressures were within preferred limits.

Testing was conducted in accordance with NORSOK U101 guidelines.

Maintenance & Hygiene

The BIBS is cleaned and prepared for oxygen use, with components degreased, ultrasonically cleaned and assembled in a controlled workshop environment.

The mask should be included within a Planned Maintenance System (PMS). Refer to the product manual for maintenance and cleaning procedures, alongside relevant IMCA guidance, including IMCA D018, Section 5.2.

Associated Equipment

The following equipment is available separately to support Delta BIBS installations in hyperbaric chambers.

Back Pressure Regulator (BPR)

Order code: HBB-301

The C-Tecnics Back Pressure Regulator is a negative-biased, dome-loaded regulator for oxygen breathing gas applications. It protects the diver from excessive negative pressure during exhalation. Positioned inside the chamber, it is normally connected to the BIBS manifold block.

Maximum pressure rating: 50 bar
Control range: Up to 30 bar bias
Bias spring: Up to 3 bar
Design proof pressure: 150% of maximum working pressure
Body material: Brass

Oxygen Supply Pressure Regulator

Order code: HBB-300

The C-Tecnics Pressure Regulator reduces oxygen supply pressure from a 200 or 300 bar source to the working pressure required by the Delta BIBS. Adjustment is required during chamber compression and decompression to maintain the required supply pressure relative to chamber pressure.

Maximum inlet pressure: 300 bar
Outlet pressure range: Up to 40 bar
Design proof pressure: 150% of maximum working pressure
Body material: Brass

Chamber BIBS Manifold Block

Order code: HBB-302

The brass C-Tecnics BIBS Manifold Block accommodates the supply and exhaust quick-connect fittings for two Delta BIBS masks. Additional ports allow multiple blocks to be connected in series and positioned around the chamber where more BIBS masks are required.

Oxygen cleaning is available on request.

Female Quick-Connect Fittings

Chamber-side female quick-connect fittings accept the corresponding male connectors on the Delta BIBS hoses.

HB-036: Inlet quick-connect with 1/4" NPT connection, to accept the BIBS supply hose
HB-035: Outlet quick-connect with 3/8" NPT connection, to accept the BIBS exhaust hose
