The GCC ductless chemical fume hood is a self-contained laboratory ventilation system designed to capture and filter chemical vapors without connection to an external exhaust duct. Contaminated air is drawn into the enclosure, passes through the appropriate filtration system, and the filtered air is returned to the laboratory.
Self-Contained Ductless Design – No external exhaust duct or building exhaust system is required. Filtered air is returned to the laboratory.
Activated Carbon Filtration – Uses activated carbon filtration for adsorption of compatible chemical vapors and VOCs.
Modular Filter System – Filter configurations can be selected according to the type of gases, vapors, and particulates generated during laboratory operations.
Automatic Airflow Control – Intelligent airflow control maintains a stable face velocity of 0.4–0.6 m/s for effective containment.
Real-Time Face Velocity Monitoring – Displays airflow velocity continuously and provides alarm reminders when airflow falls outside the preset range.
Filter Saturation Monitoring – Online VOC monitoring helps detect increasing contaminant levels and provides timely filter replacement alerts.
Fan Monitoring System – Monitors fan operating status, airflow conditions, and system faults with alarm notifications.
Temperature & Humidity Monitoring – Displays laboratory temperature and humidity in real time, with adjustable alarm settings.
High Filtration Performance – Designed for laboratory applications requiring controlled capture and filtration of compatible chemical vapors and particulate contaminants.
Automatic Safety Alarms – Integrated monitoring and alarm functions help identify abnormal airflow, fan faults, and filter saturation conditions.
Portable Installation – Compact self-contained design allows installation without dedicated laboratory exhaust infrastructure.

Laboratory air containing chemical vapors is drawn into the front opening of the fume hood.
The internal airflow directs contaminated air toward the filtration section.
Activated carbon and other selected filter media adsorb or capture compatible chemical vapors and particulate contaminants.
The filtration system is continuously monitored for airflow and filter saturation.
Filtered air is returned to the laboratory without connection to an external exhaust duct.
When filter saturation or abnormal airflow is detected, the control system provides an alarm to prompt inspection or filter replacement.
The ductless chemical fume hood is suitable for controlled laboratory operations where the chemical inventory is known and compatible with the selected filter configuration, including:
Pharmaceutical GMP laboratories
Constant-temperature and humidity laboratories
Sample preparation and pretreatment
Sample weighing and dispensing
Chromatography and analytical laboratories
Teaching and demonstration laboratories
Cleanroom-adjacent testing areas
Forensic laboratories
Research laboratories
