Chambre Airtight Tester par
A modular blower-door room airtightness tester with adjustable doorway panel, calibrated fan and dual-channel pressure/flow gauge.
- Temporary adjustable doorway sealing system.
- Calibrated reversible fan with multiple flow ranges.
- Dual-channel multipoint airtightness testing.
Introduction de produit
This tester temporarily seals a doorway with an adjustable fabric panel and installs a calibrated variable-speed fan in the lower opening. The fan pressurizes or depressurizes the room while a dual-channel gauge monitors enclosure pressure and fan flow. Multiple pressure points can be used to derive leakage flow and an airtightness curve for cleanrooms, containment rooms and protected enclosures.
Key Features
Reversible calibrated fan provides pressurization or depressurization.
Interchangeable flow rings extend useful airflow measurement range.
Dual-channel gauge displays enclosure pressure and leakage flow.
Automatic pressure stepping supports repeatable multipoint testing.
Modular components pack into transport bags for field use.
Préoccupations du client produit
Room leakage must be measured over a controlled pressure range despite differing doorway sizes, environmental baselines and widely varying enclosure tightness.
Door openings differ between rooms and projects.The telescopic frame and flexible panel adjust to a practical range of doorway dimensions.
One fan range cannot measure both tight and leaky rooms accurately.Interchangeable calibrated flow rings adapt the fan to different leakage levels.
Wind and stack pressure bias a single reading.Baseline capture and multipoint testing distinguish environmental offset from fan-induced pressure.
Large test assemblies are difficult to transport and install.The collapsible frame, fabric panel, fan and gauge pack into modular carrying bags.
