Throna HEXAGON – ESD cleanroom chair
Suitable for ISO class 9 to 6 cleanrooms: this ESD-safe chair combines ergonomics and comfort with static discharge protection. Finished in durable Nero black synthetic leather and steplessly height-adjustable between 42 and 55 cm.
The Throna HEXAGON ESD cleanroom chair combines advanced ergonomics with comprehensive electrostatic protection. Specifically engineered for demanding use in controlled environments and cleanrooms up to ISO Class 6, it prevents electrostatic discharge (ESD) risks that could compromise sensitive electronic components and critical processes.
Engineered with high-grade conductive materials, the HEXAGON ESD ensures continuous, dependable grounding in accordance with IEC 61340-5-1 standards. Both the specialised ECR 7 ESD upholstery and the conductive castors and base dissipate static build-up immediately. The sealed gas lift eliminates oil and grease particulate emissions, while the fully enclosed seat underside prevents particle accumulation and dispersion within critical spaces.
