The 3M Scott safety MODUL AIR Airline Trolley is designed for applications where a more prolonged air supply duration is required—consisting of a lightweight stainless steel hose reel unit and cylinder frame that can be used separately or together. The trolley frame can carry two Sabre cylinders, with a modular option for stacking two more on top, allowing two or four-person operation.
Kits options include wheels and handle. Continuous operation is possible when non-return bleed valves are paired with the cylinder connectors allowing cylinder replacement during operation, creating an airline trolley system—ideal for deployment where an alternative compressed air supply is absent. Fifty-litre cylinders are available for extra long-duration activities.
Air is fed from the trolley by hoses available in PVC or Anti Static 1-90M. A Flite set enables connection of a user to the medium pressure airline. Flite set consists of a harness with padded should strap for donning, line connector and tempest demand valve for air regulation. Mask to be ordered separately, use Vision 3, or Promask Positive Pressure. An escape Flite option is available, deployed in airline supply failure, containing a small short duration cylinder for back up supply. Access to hard to reach areas is made more comfortable without a large BA set; movement is also less restricted.
An optional AFU removes oil mist, particulate matter and water when connecting to an alternative air source, like a factory compressor. A single distress unit (DS4) can be fitted alarming in the event of air pressure drop.
For applications like aircraft paint spraying or removal of material, a RAS positive pressure system is available. Comprising of Flite and Face mask with filter connection. The filter is used when approaching the working area, where oxygen is at safe levels. Once in the working area, connect to the airline system, which will provide full respiratory protection.
