SF Maintenance Equipment Fundamentals

Compressed to liquid form, larger amounts of SF 6 can be stored in smaller volume storage containers. For example, a typical 1.6 ft3 (44 liter) type-b cylinder is capable of storing approximately 115 lbs. (52 kg.) of SF 6 in liquid form. In gaseous form, the same cylinder will store only approximately 25 lbs. (11 kg.).
