能を低下させてしまう。2. Description of the Related Art Conventionally, in order to remove dust in the air, an intake filter is composed of a pre-filter for collecting coarse dust and a high-performance filter placed downstream of the pre-filter for capturing fine dust. For each filter, the required number of filters is stored in the filter chamber according to the processing air volume and used. However, if mist such as oil is contained in the air in addition to dust, the oil collected by the prefilter is absorbed by the filter medium and retained in the filter medium, increasing the pressure loss of the prefilter. And the performance of the filter will be degraded.

When the mist removal filter is provided, a space for providing a mounting frame for mounting the mist removal filter and a maintenance space for replacing the mist removal filter are required, which causes a problem that the size of the filter chamber becomes large. . Also, an inspection door had to be added to the chamber in order to replace the mist removal filter. Therefore, there is a problem that the cost for manufacturing the intake filter increases and the occupied area for installing the filter chamber becomes large. An object of the present invention is to provide an intake filter in which a mist removing filter can be installed without increasing the size of the filter chamber.

In the intake filter, the mist removing filter is arranged on the upstream side of the pre-filter, and the mist removing filter and the pre-filter are attached to the same filter attachment frame in this order. It is preferable that the mist removing filter and the pre-filter are mounted on a filter support of the same filter mounting frame in this order, and a flange portion of the pre-filter is fixed to the filter mounting frame by a filter retainer. The "mist removing filter" in the present invention means a filter for collecting and removing mist-like substances such as oil mist in the air.
