Containment / Airflow / Compliance
Laboratory Fume Hoods
Benchtop, floor-mounted / walk-in, polypropylene and special-purpose fume hoods, evaluated on containment, airflow and site integration rather than face velocity alone.

01 / Types
One family. Distinct duties.
Each configuration serves a different footprint, chemistry and workflow. Selection follows the actual application, not a single number.
Benchtop
Standard bench-mounted hoods for general wet chemistry and routine procedures on a worktop.
Floor-mounted / Walk-in
Full-height enclosures for tall apparatus, carts and large-scale setups requiring floor access.
Polypropylene (PP)
Corrosion-resistant PP construction for strong acids and alkalis, with heat and rigidity limits to consider.
Special-purpose
Application-specific enclosures configured around unusual chemistry, geometry or exhaust requirements.
02 / Performance
Beyond face velocity.
Containment is a system outcome. Face velocity is one input among many that must be balanced and verified.
Containment performance
How reliably contaminants are captured under real operating and cross-draft conditions.
Face velocity
Average inflow at the sash opening, evaluated with uniformity -- not as a standalone rating.
Sash
Sash type and position affect opening area, operator protection and energy use.
Liner
Interior liner material selected against the chemistry, temperature and contact time.
Exhaust airflow & static pressure
Volume and pressure must match the duct system, fan and building conditions.
Fan control
Constant-volume or VAV control with alarm and monitoring where the application requires it.
03 / Evidence
Test methods, stated plainly.
ASHRAE 110 and EN 14175 are test methods. They describe how containment is measured. They are not general product certifications and do not automatically cover every model or site.
Method reference
ASHRAE 110
A containment test procedure using tracer gas and airflow visualization. Results apply to the specific unit, configuration and conditions tested -- reported as measurements, not as a blanket certification.
Method reference
EN 14175
A European standard series covering type testing and on-site testing of fume cupboards. It defines test procedures for containment and airflow; reported results are scoped to the tested product and installation.
Performance is site-dependent
Room cross-drafts, make-up air, duct runs, fan capacity, static pressure and building controls all affect containment. Final commissioning and acceptance are completed at the project location by qualified local teams.
04 / Selection
A defined selection process.
Selection resolves into a documented set of decisions: chemistry, configuration, airflow, control and interfaces.
Define application
Chemicals, concentration, temperature, apparatus size and workflow.
Choose type & liner
Benchtop, walk-in or PP, matched to chemistry and available space.
Size airflow & control
Exhaust volume, static pressure, fan and constant-volume or VAV control.
Confirm & verify
Written confirmation, applicable standards and on-site testing at handover.
