What Is an Exhaust Connection on a Safety Cabinet?

Storing chemicals that release strong vapours? The right exhaust connection can make your storage setup easier to manage.

An exhaust connection is an outlet, usually located on the top of a safety cabinet, that allows the cabinet to be connected to an external ventilation system.

It can help remove or control chemical vapours when ventilation is required for a particular application.

When Is External Exhaust Useful?

External ventilation may be considered when storing chemicals that are:

• Highly volatile

• Strong-smelling

• Toxic or harmful by inhalation

• Likely to release vapours during storage

For example, some laboratories, factories and chemical handling areas may need additional ventilation when storing volatile solvents or other hazardous chemicals.

The exact requirement depends on the chemical, SDS, cabinet design and local regulations.

Does Exhaust Replace Cabinet Safety?

No.

An exhaust connection is only part of the overall storage system.

It does not replace the cabinet's fire protection, spill containment or other safety features.

For flammable chemicals, the cabinet itself should be suitable for the intended application. Ventilation should be designed as a separate part of the installation.

What Size Is the Exhaust Connection?

The size depends on the cabinet model and ventilation design.

For example, some SUPER chemical and gas storage cabinets use a 75 mm exhaust connection.

The connection should be matched with the planned duct and ventilation system rather than selecting the duct size independently.

What Should Buyers Check?

Before ordering, confirm:

• Exhaust connection diameter

• Connection location

• Required airflow

• Duct requirements

• Whether an external fan is needed

• Chemical compatibility of the duct material

For a customized cabinet, these details should be confirmed before production.

Need a Cabinet with Exhaust Connection?

SUPER can provide chemical and gas storage cabinets with different exhaust configurations, including models with 75 mm exhaust outlets.

If you tell us the cabinet size, chemical being stored and ventilation requirements, we can help confirm a suitable configuration.
