A compression system including a compressor driven by a motor, an optional accumulator, a liquid/gas separator, heat exchangers in the form of a condenser and an evaporator, expansion valves and conduit in the form of piping to connect these components together. The liquid/gas separating means is a lubricant separator, typically a cylindrical horizontal or vertical vessel used in conjunction with a gas compressor. The lubricant separator accepts discharge flow from the compressor which includes a mixture of a "smokeless" lubricant and refrigerant gas in a range of particle sizes forming a fluid stream, separates the refrigerant gas from the lubricant and collects the lubricant for reuse in the compressor. Because the lubricant used in the lubrication system rapidly agglomerates into a larger size droplets and does not produce the aerosol, the separator does not require a coalescer element to coalescer aerosol and does not require a manway for serving the coalescer element. The coalescer element is replaced with a more reliable and durable mesh pad to agglomerate the larger sized droplets. The overall size and space requirements associated with the separator are reduced.
