Hatlapa L50, L80

The document summarizes information about compressor types L50 and L80II. L50 has two staged cylinders in a W-arrangement with a single-throw crankshaft and single acting trunk pistons. L80II has two opposed cylinders in a four-throw crankshaft arrangement. Both feature combined suction and pressure valves in both stages and are air cooled by an axial fan. Lubrication is provided by a gear pump driven by the crankshaft, with oil pressure controlled by a pressure gauge and switch.
