PURPOSE:To replace simultaneously a filter set and oil, which are all contaminated, by integrating an oil pan into a filter set removably installed to a filter frame. CONSTITUTION:An engagement hole 7 is installed respectively to the upper part and the lower part of a cover 6 for a fan 4. In the front of this cover 6 is removably installed a filter frame 9 which is provided with claws 8 to be engaged with the engagement holes 7. Moreover, in the front of the filter frame 9 is removably installed a filter set 10 for catching oily dust. In the lower part of this filter set 10 is installed on oil pan 11 in an integrated manner. Therefore, this construction makes it possible to replace simultaneously the contaminated filter set 10 and the oil pan 11 containing faulty oil, thereby facilitating cleaning. |
