3M™ Modulair Airline Trolley System

The 3M™ Modulair is suitable for use in situations where clean and adequate oxygen levels air cannot be guaranteed or portability is essential.

The Modulair by 3M™ is a compact, easy to use airline trolley system designed to provide portable clean air in restricted access areas. Versatile and robust, it consists of a lightweight stainless steel hose reel unit and cylinder frame that can be used independently or together. The frame is designed to carry a pair of cylinders and where required an additional frame can be vertically stacked to allow connection of up to four cylinders. This in conjunction with proven 300 bar high performance pneumatics delivering up to 1000 litres of breathing air per minute, permits four people to work at the same time. Long duration operation is made simple through adjustable cylinder bands and high pressure cylinder connectors to accommodate a variety of cylinder sizes at both 200 and 300 bar. Non-return bleed valves fitted to the cylinder connectors enable cylinders to be replaced independently for continuous operation. The Modulair by 3M™ is certified to AS/NZS 1716:2012 The Modulair is also CE marked in accordance with EN139

To safeguard against any drop in air supply pressure the 3M™ Scott™ Modulair can be fitted with a medium pressure warning whistle or a DS4 (automatic distress signal unit) for both audible and visual alarms if the airline supply pressure falls below 3.8-4.1 bar (55-60 psi). In either case, the operation of the alarm informs safety rescue personnel to switch over to the reserve air supply, change cylinders or initiate evacuation procedures as appropriate.
