It is a standard machine hatch.

A detachable machine hatch that allows for an opening size that is difficult to achieve with a door. Some work is required for detachment, so infrequent opening and closing is a condition. Additionally, the internal aluminum frame of the TH40 is sturdier and can accommodate larger sizes compared to the TH30. When the height dimension increases, it is recommended to use a plus bar to increase the engagement with the outer frame. ◇TH40◇ The TH40 can accommodate a large size with an effective height dimension of 4500mm. Multiple machine hatches can be removed one by one and then put back in place. The three-sided frame specification is affected by unevenness in the floor, so it is necessary to ensure a level floor. The four-sided frame specification, which emphasizes airtightness, tends to have the lower frame obstructing, so it is common to make the lower frame detachable. Additionally, when the height dimension increases, it is recommended to use a plus bar to increase the engagement with the outer frame. ◇TH30◇ The TH30 can accommodate an effective height dimension of up to 3000mm. The basic functions are the same as the TH40. Some work is required for detachment, so infrequent opening and closing is a condition.

No unevenness, easy to manage hygiene! Detachable panel flat type.

Flat-type removable machine hatch with minimized protrusions ◇THF40◇ Windows and doors installed on the walls of clean rooms need to eliminate protrusions that could obstruct airflow as much as possible. This is a flat-type removable machine hatch that reduces the number of tightening handles and grips for each panel. Additionally, even for tall machine hatches, no ladder or similar equipment is required for the removal and installation process. ◇THF50◇ Typical removable machine hatches have exposed tightening handles and grips to secure the removable panels. In clean rooms, dust and debris can accumulate on these hardware protrusions, and the protrusions can disrupt airflow within the clean room, potentially affecting product quality. The full flat-type removable machine hatch "THF50" features a design that minimizes surface protrusions to the utmost, meeting the highest JIS airtightness performance grade, A-4. It is the ultimate removable machine hatch for clean rooms, ideal for industrial clean rooms (ICR) in semiconductor and precision manufacturing, as well as for bio clean rooms (BCR) that consider GMP and HACCP standards.
