Ductless Chemical Fume Hood Safety Mobile Fume Cupboard For Laboratory

A ductless fume cupboard—sometimes misspelled as fume cardboard—is a fully self-contained chemical safety cabinet designed to protect laboratory personnel from hazardous vapors, chemical fumes, and toxic gases. This mobile filtration fume hood uses advanced activated carbon filters and HEPA filtration to purify contaminated air before recirculating it back into the room, eliminating the need for external ducting.

The GCC Ductless Fume Cupboard offers reliable chemical protection, stable performance, and easy mobility, making it ideal for laboratories with limited space or facilities without central ventilation systems.

Airflow Pattern & Exhaust Principle

Air Flow Pattern

• Room air enters through the sash.

• Airflow captures chemical vapors immediately at the work area.

• Contaminated air is drawn into the filter module.

• Clean, filtered air recirculates back into the room.

Exhaust Principle

1. Dirty air enters the fume cupboard through the front opening.

2. Air mixes with chamber fumes and is pulled upward.

3. Air splitting design reduces turbulence and enhances capture.

4. Toxic air passes through specialized filters and is safely purified.
