1. Introduction
1.1 Functional description
The AP RBV07 Swivel inflator range is a series of breathing gas inflators designed for use
with any AP Inspiration rebreather fitted with back-mounted counterlungs. Their unique
property is the swivel design with rotating inlet ports - which make it easy for the diver to plug
in various breathing gasses before and/or during the dive.
1.2 Servicing
Before servicing these swivel inflators, you must receive instruction and certification in the
maintenance of these inflators by AP Diving Ltd.
Without the correct training it is possible to service and configure the RBV07 Swivel inflators
incorrectly in an unsafe manner. Factory or Dealer prescribed service for these inflators is
recommended at least once annually.
The Inspiration, Evolution and Evolution+ closed circuit rebreathers’ CE certification to
EN14143 is unaffected by the fitting of this RBV07 Swivel inflators.
The RBV07 swivel inflators meet the requirements of the Personal Protective Equipment
Directive 89/686/EEC – CE certification when fitted to an AP Diving rebreather.
WARNING: When servicing the RBV07 swivel inflators it is VERY important that all parts
that may suffer wear and tear get replaced. It is also very important that the correct tools are
used to avoid damaging any part of the inflator in the disassembly and assembly process.
Please don’t try to save money by re-using parts that really should be replaced during a
proper servicing action.
B
The numbers between brackets after the part names in the disassembly and assembly
chapters correspond to the sequence numbers in the diagrams in chapter 2.
1.3 Warranty
The RBV07 Swivel inflators are covered by an AP 2 year warranty against defects in
materials or workmanship. This warranty is only offered to the original purchaser and is not
transferable. A copy of the receipt must be presented whenever obtaining warranty service.
1.4 Copyright and Applicable Law

3. General Information
3.1 Four versions
There are four versions of the RBV07 Swivel inflator within the range. All four versions are
available in both a Diluent as well as an Oxygen model, making a total of eight different
models.
Note: The oxygen models have the letter "A" as a suffix in their part code.
3.2 Gas flow paths
In the pictures below (sections 3.3 to 3.6) the dotted arrows indicate the gas flow through the
inflator when the push button is operated. These are "on-demand" gas flow paths which are
normally blocked but can be temporarily opened by pushing the green or blue push button.
In the case of the four Swivel Inflator models with Flowstop shutoff (sections 3.5 & 3.6) the
solid arrows indicate a straight-through gas flow path through the inflator i.e. a continuous
gas flow regardless of whether the push button is operated. The gas flows uninterrupted from
the inlet through the inflator to the outlet to which the GC3 Flowstop is attached. The gas flow
can of course still be blocked by means of the slider on the GC3 Flowstop.
3.3 Single Swivel Inflators - RBV07 & RBV07A
The RBV07(A) has one MP (Medium Pressure) inlet and one MP outlet.
The RBV07(A) allows the diver to connect either an onboard or an offboard gas source. This
is made easy by virtue of the swivel design in which the inlet port section of the inflator can
rotate through 360 degrees.
The gas flow path is "on demand", i.e. gas only flows through when the button is pushed.

3.4 Dual Swivel Inflators - RBV07/DUAL & RBV07A/DUAL
The RBV07(A)/DUAL has two MP inlets and one MP outlet. Both inlets rotate to facilitate
connection to wherever the gas sources are located.
The extra inlet (on the bottom in the picture below) allows the simultaneous connection of
another gas source, either onboard or offboard. Each gas source can be operated by its own
separate push button.
The gas flow paths are both "on demand", i.e. gas only flows when one of the buttons is
pushed.
