6. Clean and Replace Service Parts
The servicing of the RBV07 Swivel inflator contains 4 “action groups”:
1. Removing and binning all parts that should be replaced. This includes all O-rings.
2. Depending on the gas content the RBV07 Swivel inflator is exposed to, keep it in oxygen
service. The CGA (Compressed Gas Association), US Navy, UK’s HSE and the EIGA
(European Industrial Gas Association) all recommend that breathing gasses with an
oxygen content of 23.5% or higher should be treated as 100% oxygen. However, some
technical training agencies still use 40% as the maximum percentage that is allowed for
equipment that is not in oxygen service.
AP Diving advises to err on the side of safety, and to use the value of 23.5% as the
cutoff percentage beyond which the equipment must be in oxygen service.
If in doubt: keep it in oxygen service, as that only takes a little bit more effort.
3. Ultrasonic-cleaning of all disassembled metal parts. This is mandatory if the RBV07
Swivel inflator is to be kept in oxygen service, but recommended in all other servicing
situations.
4. Lightly grease new parts, fit them, and re-assemble the RBV07 Swivel inflator with the
correct tools and the correct torques. Use oxygen-compatible grease, and avoid
contaminating the metal parts after cleaning. Use the smallest amount of grease
possible.
The use of rubber gloves while re-assembling the RBV07 Swivel inflator is mandatory if the
RBV07 is to be kept in oxygen service. This is to avoid rendering the RBV07 Swivel inflator
unclean due to human touch (skin oils, sweat).
