Product Details
Since the introduction of the first production model in 1999, the KISS Classic has earned a reputation as the most durable, reliable, and easiest to maintain closed circuit rebreather on the market. Due to its ability to be used in harsh, and extremely remote locations - which have included some of the deepest cave systems in the world - it has also obtained status as a true expedition-grade rebreather.

From the start, the Classic’s counterlung case has been an integral part of the system, serving as a protective shell for the unit’s two counterlung’s, a supporting frame for the loop and scrubber assembly, and a nesting bracket for both the oxygen and diluent supply cylinders.

In 2013, the Classic’s counterlung case was redesigned to provide greater access at the top. This allowed for easier installation and removal of the rebreather’s counterlung’s for cleaning.
The same update saw the addition of a new backplate design that was based on the original Explorer model released in 2010 but had some modifications. The new plate more closely follows the contours of the counterlung case to ensure the unit’s overall profile remains as close to the diver’s back as possible, creating the optimum work of breathing (WOB). This redesigned case also became a replacement item for Explorer models and the original Classic KISS.
This new counterlung case and backplate combo allows for a broader number of harness configurations and can accommodate a number of wings designed for either double tanks or CCRs.
The scrubber on the Classic is an axial flow design, which means the expired gas from the diver's lungs travels down a center tube and back up through the scrubber material to remove carbon dioxide (CO2). The beauty of the Classic’s axial scrubber is that it is easy to pack and resistant to channeling.
Fully packed, the scrubber holds approximately 6.4 lbs of Molecular 797 grade (8-12 Mesh) Sofnolime, or 5.5 lbs. of the larger granular 408 grade (4-6 Mesh) absorbents like Dreagersorb.

The scrubber head is attached to the counterlung case’s central spine by two large stainless flathead screws. From there, the scrubber canister fits to the head from below and is held in place by means of a large draw nut, which meets a long threaded shaft that extends upward from the bottom of the scrubber.
Earlier versions required the draw nut to be tightened with a special hand tool. One of the changes made for 2014 models is a redesign of the draw nut so that it can be easily installed and tightened with one hand, remaining securely in place until the time to take it apart.
The large knob portion of the draw nut is made from a solid piece of extremely tough, crack-resistant black PVC that has been milled to allow the top of the bronze draw nut to fit inside. The knob is held in place with two stainless hex head screws ensuring the knob can not spin independently of the draw nut during installation or removal. (Note: new style draw nut works with all earlier model Classic’s and is available as a replacement part.)
The Classic Explorer is a true mCCR, as it does not have any on-board electrical components such as a CPU-controlled solenoid. The diver is provided PPO2 information through a basic PPO2 display and/or dive computer connected to the three 22-D type oxygen sensors housed in the scrubber. The cell chamber for the three sensors sits below a removable sensor plate in the top of the scrubber head.

At the factory, the plate is tapped with either one or two ports for the installation of watertight cables. At the time of order, the diver may have their Classic Explorer configured to work with either one or two Shearwater Research computers via Fischer connections, or have them completely hardwired in the system. Other options include a HUD, Shearwater NERD, or basic PPO2 display system. Two redundant display systems are recommended for all technical dives.
The Classic Explorer comes standard with two counterlung’s that can be either 2 or 4-liter sizes, depending on what best matches the tidal volume of your lungs. The counterlung’s are attached to the scrubber head from the inside of the counterlung case. These back-mounted lungs leave the diver’s chest area clear of obstructions, and also reduce the number of hoses and fittings as compared to the over-the-shoulder counterlungs found on other many rebreathers. Most divers use one 2 liter and one 4-liter counterlung.
The automatic diluent valve (ADV) is an important component on a closed-circuit rebreather, as it introduces necessary diluent gas into the breathing loop to maintain a breathable gas mixture.
The ADV on the Classic Explorer uses a simple tilt valve mechanism that functions much like a regulator's second stage, but with fewer parts. This makes it less prone to seize or fail. Mounted in the side of the scrubber’s head, the ADV is in an optimal location to be automatically activated should the volume of gas in the loop compress during decent or as a result of the loop volume being breathed down through slightly higher than normal metabolism.
As a hands-free alternative when the additional diluent is needed, the diver can also conveniently actuate the ADV by performing a slightly stronger than normal inhalation, which will trigger the tilt valve to briefly open.

All KISS Classic Explorer and Spirit model Closed-Circuit Rebreathers come equipped with a bailout valve (BOV) mouthpiece as part of the system. The BOV has two main components: the Dive Surface Valve (DSV) which is used to open and close the rebreather’s breathing loop, and a 2nd stage regulator, which is built-in to the mouthpiece to allow the diver to breathe open circuit when not on the loop. The dual functions of the BOV allows the diver to quickly and easily exit the breathing loop while at the same time switching to open circuit with a simple twist of a knob. Should such a need arise as a result of a malfunction underwater, the BOV can play an essential role in preventing panic by providing an immediate source of safe breathing gas of a known oxygen percentage for your next breath. It can also be used for adding diluent gas to the breathing loop.
The Hollis BOV is included as part of the Classic Explorer Open Water package. Other mouthpiece options include the KISS DSV and the Poseidon BOV.
NOTE: * The KISS Classic’s onboard diluent bottle is not adequate bailout. When diving a rebreather, a separate bailout bottle should always be carried.
The Classic Explorer’s counterlung case comes with two powder coated aluminum rails for mounting a pair of gas cylinders to the backside of the unit. Along with the rails are a series of slots for installing anything from stainless hose clamps to 1.5 inch or 2-inch wide cam bands to hold aluminum or steel gas cylinders in sizes between 13 and 19 cu.ft. in place.
