Sanyawit: Specialists in Clean Air Systems and Cleanrooms for Hospitals

In healthcare environments, the quality of the air is inseparable from the quality of care. A cleanroom or surgical suite where airborne contamination control fails isn't just a technical problem — it's a patient safety crisis. Sanyawit Co., Ltd. (บริษัท สัญญวิศว จำกัด) has spent over 16 years building the expertise to ensure that never happens.

From Construction Contractor to Clean Air Specialist

Founded in 2008 by Mr. Sanya Srisuwan, Sanyawit began as a construction and factory maintenance contractor with API Group as its primary client. A pivotal expansion came in 2015 when Mr. Phawat Sirinphomonee took over management and drove the company into specialized HVAC engineering — specifically the design and maintenance of air treatment systems for hospitals.

Core Services

Consult — Deep consultation on system requirements, matching solutions to the specific operational needs of the facility rather than selling standard products.

Design — Engineering systems that comply with Ministry of Public Health standards and international benchmarks, ensuring regulatory approval and safe, reliable operation.

Service and Maintenance — Ongoing support to keep systems performing at peak efficiency, including scheduled performance verification and compliance testing.

Clean Room Expertise

Hospital cleanrooms demand precision engineering: controlled air pressure differentials, HEPA filtration, and contamination prevention between spaces. Sanyawit has built specialized knowledge in these systems over its operating history, making it a trusted partner for hospitals seeking reliable cleanroom certification and maintenance.

Why Hospital HVAC Needs Specialists

Healthcare HVAC differs fundamentally from commercial buildings. It must meet ISO Class standards, support positive/negative pressure rooms by ward type, and undergo rigorous periodic performance testing. Design or installation errors can directly cause Healthcare-Associated Infections (HAI) — a severe risk to patients and a reputational catastrophe for facilities.
