MSA steel and composite compressed air cylinders meet a wide range of applications, needs, and budgets. Composite cylinders with aluminium liner, over wrapped with carbon and glass fibres, are 50 % lighter than the traditional economic steel construction. MSA offers cylinder versions with 200 and 300 bar service pressure and 2 to 9 litre capacity. Additional safety is provided by a full choice of valve options such as integrated gauge, ratchet hand wheel to prevent unintended closing and flow restrictor in case of valve breakage.
