In the drawing, reference numeral 1 denotes a support frame that is rectangular in plan view. Legs 2 are integrally provided at the corners of the support frame 1. Wheels 3 or sliding rails (not shown) are provided at the lower end, and a vinyl curtain 5 with an open bottom is attached around the leg group 2 so as to form a downwardly open working space 4 inside. A casing 6 is placed on the support frame 1, and the casing 6 includes a filter chamber 7 that opens into the work space 4, and a fan chamber 8 that opens on one side adjacent to the filter chamber 7. It is provided. A grill-type outlet 9 is provided at the lower opening of the filter chamber 7, and an air purifying filter 10 is disposed above the outlet 9.
Inside the fan chamber 8, there are a filter chamber 7 and a fan chamber 8.
An electric fan 12 fixed to a partition wall 11 between the fan chambers 8 and 7 is disposed with a discharge port 11' facing the upper part of the inside of the filter chamber 7, and a pre-filter 13 is provided at a side opening of the fan chamber 8.
