The Erlab Captair 391 Smart is an advanced ductless weighing enclosure engineered for precision micro-weighing of hazardous powders while protecting both laboratory personnel and the surrounding environment. Designed with Erlab's proven filtration technology, the Captair 391 Smart delivers exceptional weighing stability, controlled horizontal airflow, and certified containment without the cost or complexity of ducted laboratory infrastructure.

Unlike traditional weighing enclosures, the Captair 391 Smart integrates intelligent wireless monitoring that provides real-time visibility into airflow, filter status, alarms, humidity, and temperature from a computer, tablet, or smartphone. This continuous monitoring helps laboratories maintain compliance while maximizing user safety.

Its adaptable filtration system combines activated carbon filtration for chemical vapors with optional H14 HEPA filtration for particulate containment, allowing laboratories to configure the enclosure for liquids, powders, or mixed applications. The innovative Bag-In/Bag-Out (BIBO) filter replacement system further enhances operator safety during maintenance.

The Captair 391 Smart is available with multiple sash opening configurations and work surface options to match a wide range of laboratory workflows. Whether supporting pharmaceutical research, analytical chemistry, toxicology, forensic science, environmental laboratories, or academic research, the Captair 391 Smart provides outstanding protection without requiring building exhaust systems.
