There are two different versions of aromas pump hose – a left handed one and a right handed one. Both are available with a choice of four different colours of silicone tubing – Black, Blue, Red, or Yellow.

The left hand, or L version, has the pump bulb on the left when the silicone tubing is at the front of the hose and the R version has the pump bulb on the right. In both cases, the tube to the pump bulb hangs to roughly the centre of the chest if the user is seated or standing and facing forward. If the user is lying down, the hose should hang to one side or the other, rather than lie flat.

If the user will be lying down for most or all of the session, it is probably better to add a normal gas mask hose between the pump hose and the gas mask. This makes it easier to make sure the bottle is hanging down as it should. If you are including a normal hose, it may be useful to add a 1.5 metre Pump Bulb Extension Kit to make the pump bulb more accessible.

In use, there is little difference between the L and R versions, although, bearing in mind that I sell more or less the same number of each, and only ten percent of people are left handed, I guess that buyers are wanting their dominant hand somewhere other than on the bulb when pumping. I am right handed and my hose, which is several years old, is a right hand one. You don’t need to pump all the time, a few quick pumps – then leave it for a while.


Left hand pump hoses


Right hand pump hoses

As the red and yellow tubing is not completely opaque, there may be evidence of a slight darkening of the central tube over time depending on the brands of aromas used.

The golden rule with the pump hoses is to make sure the bottle stays something like the right way up. Three symbols are featured in the instructions included with each hose –


	Up to 10 mm of liquid in the bottle		Too much liquid in the bottle		Keep the bottle reasonably upright

Let the bottle hang down from the end of the silicone tubes. If you don’t keep it reasonably upright, some of the liquid may go into the connectors and reach the silicone tubes. If liquid does get into the tubes, the next time you pump, far too much vapour will be pumped into the gas mask and definitely ruin your session. Only put a small amount of liquid into the bottle as shown above.

If your activities whilst using your hose, mean that you have no way to ensure that the bottle will stay reasonably upright, you can put some cotton wool in the bottle to absorb the liquid. All the liquid should be absorbed, leaving no liquid which can run into the tubes. You should never have the bottle higher than the mask, with or without cotton wool.

One way which works really well, is to breathe out and hold your breath for a moment. Squeeze the pump five or six times to load the hose with air and aroma. Stop pumping and breathe in gently, the build-up of aroma in the hose can be quite concentrated. For maximum impact, adding an unmodified hose below the pump hose, will give more space for the pumped aromas and air to build-up. You can pump more for each breath without wasting aromas by pumping vapour into the room.

Following these guidelines should allow your pump hose to give you many years of service. A spare glass bottle is included to cover for a breakage and a spare set of bands is included to replace any which snap.

A rebreather bag will only work with a suitably modified gas mask and should never be used in isolation.
The pump hose is normally attached directly to the gas mask and any rebreather bag or additional
hoses or bubble bottle should be connected to the female end of the pump hose.
