In accordance with EN12021 regulations, the outside pressure dewpoint should not exceed -11°C. Here at Resmar, we stock Safe-Air Filtration Trollies, providing a breath of fresh air to your work. Our stock has varities of these trollies, including SAT450HD, SAT950HD, F2257A and a portable aftercooler trolley.
These units offer a smooth, controlled and uninterrupted supply of breathing quality air, which exceeds the conditions and standards of EN12021 and a number of international requirements. Designed as a rugged, long-lasting piece of equipment, the trollies are mounted in a durable polyethylene housing. Including very little ferrous components, these units integrate stainless and aluminium components, making it a suitable choice for usage even in the most formidable of environments. Its stainless steel wheeled frame means that the unit can be effortlessly manoeuvered into the users desired position. The CEJN breathing-air outlets at the back of the units have adjustable regulator inside the unit.
A supply of compressed air is connected to an input valve on the unit's side, later passing it through a 25 micron pre-filter and a 0.01 micron oil mist coalescing filter. This air can then be sent to a pneumatically controlled pressure swing dryer, which includes a desiccant media, with the abillity to both dry the air to an appropriate pressure dewpoint of -40°C. At this point the levels of carbon dioxide are monumentally lowered. Purge air from this system is now exhuasted from the unit through a silencing system. Dried air is then passed via a hopcalite catalyst filter, oxidising any excess levels of carbon monoxide, back down to safe levels of carbon dioxide. Now, the air is finaly passed through a carbon filter, meaning that it is now protected against the potential breakdown within the desiccant media. Any odour or oil carryover is now, if not removed, significantly reduced to less then 0.003ppm.
These Breathing-Air Filtration Trollies are certainly a safe and reliable source of air, exceeding many international breathing air standards. You can also be confident that you are now completely protected against any harmful levels of carbon dioxide and carbon monoxide.
