In clean rooms and various testing rooms, the "observation windows" and "entrance doors" installed as equipment require various functions (such as airtightness and thermal insulation) that differ from standard architectural fittings. Sanwise Corporation develops, manufactures, and sells such specialized fittings for equipment. From small inspection openings to large doors for the entry and exit of machinery, sizes vary, and functions range from static electricity prevention to thermal insulation and high airtightness. Each item is custom-made to meet the specific requests of our customers. We respond promptly to inquiries and quote requests, so please feel free to consult with us!
