GTI 658 Blower Door System – Dual-Fan & Triple-Fan Airtightness Testing Kit for Large Buildings

The GTI 658 Blower Door System is a next-generation air tightness tester designed for large building envelopes, commercial structures, and energy-efficient constructions. Engineered with dual- and triple-fan compatibility, this system supports both pressurization and depressurization methods, meeting ISO 9972, ASTM E779-03, and CECS 704-2020 standards.

Featuring a 3.2-inch LCD, RS485/WiFi connectivity, and advanced PC software for on-site reporting, the GTI 658 enables precise control of flow rates and test pressure. With 8 flow control levels and interchangeable nozzles, it delivers fine-grained leak detection in real time. The adjustable aluminum frame and high-seal nylon cover allow seamless installation across various door sizes.
