Negative Pressure Isolator
OEB5 containment at controlled negative pressure — for potent, sensitizing and radionuclide-contaminated material processing where operator protection is the primary design driver.

Overview
The Fenggu Negative Pressure Isolator maintains a controlled negative-pressure barrier between the operator and the material being handled, protecting personnel from potent, sensitizing, infectious or radionuclide-contaminated substances. Filtered supply air enters through the isolator ceiling and is drawn through the working chamber to HEPA-filtered exhaust, so any leak path draws air inward rather than outward. All operator interaction with the product takes place through sealed glove ports, with no direct contact between operator and process.
Chamber pressure, material and glove-port configuration are tailored to the containment level and process required — from routine potent-compound handling up to OEB5 operator protection for the most demanding actives.
Key Features
- Continuous negative pressure (−80 to −50 Pa), maintained and monitored throughout operation
- Designed to OEB5 operator-protection level for potent and sensitizing compounds
- HEPA-filtered exhaust with a one-way exhaust valve to prevent reverse airflow
- Sealed glove-port operation — no direct operator contact with process material
- Intelligent automated control system with temperature, humidity and pressure monitoring, real-time printing and data storage
- Optional integrated weighing and explosion-proof design; low noise and low energy consumption
- SUS316L chamber; installable in a Grade D or unclassified room
