50 lb. Refrigerant Recovery Cylinder, 3/4" NPT Plug

50 Pound, Dot Class- 4BA400, 3/4in. NPT Plug- YES, Float Switch- NO, Water Capacity- 47.7 Pounds, Tare Weight- 28 Pounds

DOT Classified for recovery, recycling, service and reclaim. Liquid and vapor valves (Y valve or separate valve configurations) are installed in all cylinders. Painted yellow/gray per ARI guidelines. Float switches have 3-pin Brad Harrison connectors. Caution: Never overfill cylinders. Maximum refrigerant capacity is limited to 80% of the water capacity of the cylinder in lbs. (see table above). DOT requires cylinders to be retested every five years. Some recovery equipment uses weight scales to cut off refrigerant fill at 80% of capacity. Be sure cylinder tare weight is correct for this type of equipment. DOT Classification Example: 4BA400: 400 psi working pressure; 800 psi test pressure (double the working pressure); 1,600 psi minimum burst pressure (double the test pressure). Pressure relief/safety valve is set to release at between 75-100% of the test pressure. For example, in the 4BA400 tanks which have a 800 psi test pressure, the relief valve opens at between 600 psi and 800 psi.
