Laboratory Fume Hoods – Ducted & Ductless Fume Cupboards for Singapore Laboratories

Published:  |  Brand: JWRESEARCH by JW RESEARCH SUPPLY  |  Contact: +65 8039 3660

Every chemistry, pharmaceutical, and life-science laboratory in Singapore needs reliable containment equipment to protect personnel from hazardous fumes, vapors, and airborne particulates. A well-designed fume hood is not just a compliance requirement — it is a frontline safety barrier that stands between researchers and potentially toxic or flammable substances. At JW RESEARCH SUPPLY, we supply and support a full range of laboratory fume hoods, including both ducted and ductless (recirculating) configurations, for research institutes, university labs, hospital diagnostic centers, and industrial QC facilities across Singapore.

Why Fume Hoods Are Critical in the Laboratory

Laboratory fume hoods serve as the primary engineering control for airborne chemical hazards. They achieve containment through controlled airflow — drawing air from the laboratory across the work surface and exhausting it either externally (ducted) or through filtration (ductless). The result is a physical and aerodynamic barrier that keeps harmful substances away from the operator's breathing zone.

In Singapore, laboratories handling volatile organic compounds (VOCs), acids, solvents, or fine powders are expected to have functional fume hoods as part of their risk management controls, in line with the Workplace Safety and Health (General Provisions) Regulations and relevant Singapore Standards including SS 553 for laboratory ventilation. Nanyang Technological University (NTU), National University of Singapore (NUS), A*STAR research institutes, and private pharmaceutical labs in Tuas Biomedical Park and Biopolis all rely on properly specified and maintained fume hoods for daily operations.

Ducted vs. Ductless Fume Hoods

Choosing between a ducted and ductless fume hood depends on your laboratory's infrastructure, the chemicals in use, and your long-term operational plans.

Construction & Material Quality

All JW RESEARCH SUPPLY fume hoods feature robust construction designed for long service life in demanding laboratory environments:

Airflow & Containment Performance

Proper airflow is the foundation of fume hood safety. Our hoods are factory-tested to meet or exceed EN 14175 standards for containment, with typical performance metrics as follows:

Installation Considerations for Singapore Labs

Installing a fume hood in a Singapore laboratory requires attention to several local factors:

Maintenance & Certification Schedule

To maintain safety and compliance, Singapore laboratories should follow this recommended service schedule:

Activity Frequency Details
Face velocity check (user) Daily / Before each use Verify the airflow monitor reads within the green zone
Sash and baffle inspection Monthly Check for smooth operation, cracks, and chemical residue
Filter check (ductless models only) Monthly or per monitor alert Inspect filter saturation indicator; replace carbon filter every 6–12 months depending on usage
Full containment certification Annually ASHRAE 110 or EN 14175 tracer gas test by certified technician
Ductwork inspection (ducted models) Annually Check for corrosion, leakage, and fan bearing condition
Exhaust fan service Every 3–5 years Bearing replacement, impeller cleaning, belt tension

FAQ

What is the difference between a ducted and a ductless fume hood?

A ducted fume hood exhausts chemical vapors outside the building through ductwork connected to an external ventilation system. A ductless (recirculating) fume hood uses internal filters — typically HEPA and activated carbon — to capture and neutralize contaminants before returning clean air to the laboratory. Ducted models are preferred for high-volume or highly toxic chemical work, while ductless hoods offer flexibility in spaces where external ducting is impractical.

Do Singapore laboratories need certification for fume hoods?

Yes. Under Singapore Standard SS 553 and Workplace Safety and Health (WSH) guidelines, laboratory fume hoods must undergo annual face velocity testing and containment verification. NATA-accredited or SAC-SINGLAS accredited testing is recommended. JW RESEARCH SUPPLY fume hoods ship with initial certification documentation and we can connect you with local third-party certifiers for ongoing compliance.

What face velocity should a laboratory fume hood maintain?

International standards (ASHRAE 110, EN 14175) recommend a face velocity of 0.4–0.6 m/s (80–120 fpm) at the working sash opening. Operating below 0.3 m/s may compromise containment; above 0.7 m/s can create turbulence that pulls contaminants out of the hood. Our fume hoods are calibrated to maintain consistent face velocity across the full sash opening range.

Can ductless fume hoods handle all types of chemicals?

No. Ductless fume hoods are suitable for light-to-moderate chemical usage with known compounds that can be effectively captured by the installed filter media. They are not recommended for work with highly toxic gases, large solvent volumes, perchloric acid, or unknown chemical mixtures. Always consult the chemical compatibility chart for your specific filter configuration. Our team can help you assess whether your application is suitable for ductless operation.
