BEH Airtrailers are 4 wheeled trailers holding either 7 or 15 large capacity high pressure cylinders connected to an integral control panel supplying 4 sets of airline breathing apparatus.
Since the introduction of COSHH it has been a requirement that breathing air should be tested for quality and flow at regular intervals and that where a mobile compressor is used as the air source, tests should also be carried out every time the compressor is moved. It is also recognised good working practice that a breathing air supply should have a large reserve supply in case of failure of the primary supply.
Using the Airtrailer complies with these requirements in that it is a large supply of assured quality breathing air to BS 4275, and has a large emergency reserve supply readily available.
The cylinders operate at a pressure of 275 bar and each hold approximately 18,600 litres of assured quality breathing air. This is sufficient supply for 7 ½ continuous use by one man. The 7 cylinder trailer holds approximately 50 man hours supply and a 15 cylinder trailer, 110 hours supply.
The control panel is divided into 2 separate but inter-connected sections. The working supply section is supplied with air by all but one of the cylinders on the trailer. This spare cylinder is used to supply the emergency section of the panel. The working section of the panel utilises two parallel pressure reducing valves of a 'fail safe' design and has two gauges, one for cylinder contents and one for line pressure. There are two pneumatic warning whistles to warn of low cylinder contents and low outlet pressure.
The control panel and all the pneumatics are contained within a lockable storage box at the front of the Airtrailer. Airtrailers are road legal and being fully braked can easily be transported between sites. Two sizes of trailer are available holding either 7 or 15 cylinders. The small trailers utilise the same pneumatics and control panel as the larger trailers but have the advantage of being more easily transported.
