Claims18
An isolator device comprising:
- a work chamber;
- air supply means for supplying air of a unidirectional airflow traveling from an upper part to a lower part in said work chamber;
- and
- air discharge means for discharging said unidirectional airflow from a lower part of said work chamber, further including:
- a bulkhead provided in parallel with a peripheral wall portion of said work chamber along said air of unidirectional airflow;
- a longitudinal air outlet opened along a width direction below a of a lower end portion in a lower part of the lower end portion of said bulkhead;
- said air supply means has a rectifying member forming air in said unidirectional airflow;
- said rectifying member is provided with a frame body formed of a plurality of frame materials and two porous sheets fixed to said frame material so as to cover an upper face and a bottom face of this frame body;
- said frame material is provided with a plurality of through ports penetrating from the upper face to the bottom face thereof;
- and
- said two porous sheets covers only either one of opening portions, that is, an opening portion of said through port and also an upper face opening portion or a bottom face opening portion of said frame material in a portion brought into contact with said frame material and fixed to the frame material.
