Gearboxes with ventilation Gearbox size 04 and gearbox type GKR No ventilation is required for these gearboxes. Gearbox size 05 to 07 Special measures are not usually required when using these gearbox sizes. In borderline cases, e.g. at drive speeds >2000 rpm, we recommend that breather elements are used. We can supply these elements if required. Gearbox size 09 to 14 Ventilation units are always supplied with these gearbox sizes. Special precautions for mounting position C (motor on top) We recommend that an oil compensation reservoir is always used with gearbox sizes 09 to 14 in this mounting position. This reservoir can be purchased as an option. See technical data for illustrations and dimensions (Chapter 3…7). It is not required at high ratios or low input speeds.
