The 3M Scott safety MODUL AIR Airline Trolley is designed for applications with a more prolonged air supply duration—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. This creates an airline trolley system—ideal for deployment where a compressed air supply is absent. Fifty-litre cylinders are available for extra long-duration activities. Access to hard-to-reach areas is more comfortable without a large BA set; movement is also less restricted.

Air is fed from the trolley by hoses available in PVC or Anti Static 1-90M. A Flite set enables a user’s connection to the medium-pressure airline. The Flite set consists of a harness with a padded should strap for donning, a line connector and a tempest demand valve for air regulation. Mask to be ordered separately; use Vision 3 or Promask Positive Pressure. An escape Flite option is available, containing a short-duration air cylinder as a backup supply should the airline supply fail.

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, providing an alarm if air pressure drops.

Comprising of Flite and Face mask with filter connection. A RAS positive pressure system is available for applications like aircraft paint spraying or removal of material. 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, providing complete respiratory protection.
