3m Scott – ModulAir Trolly

The 3M Scott Modulair Trolly is a compact, easy to use airline trolly 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 Modulair Trolly 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 300 bar high-performance pneumatics delivering up to 1000 litres of breathing air per minute, permits up to 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.

To safeguard against any drop in air supply pressure, the Modulair Trolly can be fitted with a medium-pressure warning whistle that provides an audible alarm if the airline supply pressure falls below 3.8-4.1 bar (55-60 psi). The alarm informs safety rescue personnel to switch over to the reserve air supply, change cylinders or initiate evacuation procedures as appropriate.
