A twin tower gas drying system for cleaning and drying a stream of unpurified pressurized gas received from a source thereof for use of a pneumatic system. The drying system includes a manifold block provided with the plurality of ports. A separator and sump is connected to such block and to one of the ports for initially separating moisture and particulates from such stream of unpurified gas, and for directing the remainder of the stream to the one port in the block. A pair of desiccant containing canisters are threadably mounted on a surface of the block opposite that of the separator and sump by two respective threaded shuttle valves. The canisters and shuttle valves are, in addition, connected in fluid communication with certain of the ports provided in the block for supplying and removing pressurized air from the canisters. A port is provided for discharging dry clean air from the block. Other ports provided in the block exhaust purged air to the atmosphere. And, two ports are provided in the sump for respectively releasing liquid collected in the sump and for admitting pressurize air from a compressor.
