About Dynaflow
Dynaflow is an Australian company established in 1961 that specializes in Design, Manufacture, Installation, Maintenance, and Testing of Fume Cupboards, Fume Scrubbers and unique ventilation equipment for Laboratory applications. One of the chief safety tools in a laboratory is a chemical fume cabinet. A well-designed cabinet, when adequately installed and maintained, can offer an ample degree of protection to the user, provided that it is used appropriately and its limitations are understood. With the award-winning ‘Dynaflow’ Fume cupboard, the company has a long history of exports since operations commenced in 1962 as “Chemical Fume Handling Equipment".

Fume Cabinets Dynaflow
A fume cabinet is a vented place in which gases, vapours and fumes are held. An exhaust fan situated on the top of the lab pulls air and airborne contaminants in the cabinet through pipes connected to the cabinet and releases them to the atmosphere. Fume cabinets are designed specifically to provide ventilation for the safety of lab occupants during chemical uses. The airflow they provide is greatly in excess of that needed for storage of closed containers of even the most toxic of active materials. In most cabinet installations, the exhaust flow rate or quantity of air pulled through the cabinet is constant. Therefore, when the sash is lowered and the cross-sectional area of the cabinet opening decreases, the speed of airflow (face velocity) through the cabinet increases proportionally. Thus, higher speeds can be obtained by lowering the sash. Depending on its configuration, the sash may move vertically, horizontally or a combination of the two and provide some protection to the cabinet user by acting as a barrier between the operator and the experiment.
When is a Fume cabinet Necessary?
The decision for a fume cabinet for particular experiments should be made based on hazard analysis of the experiments to be conducted. Such an analysis should include:
- A review of the physical characteristics, quantity and toxicity of the materials to be used,
- The experimental procedure,
- The volatility of the materials present during the experiment,
- The probability of their release,
- The number and sophistication of manipulations and
- The skill and expertise of the individual performing the work.
