Key Features

High Airflow Performance

Designed to rapidly introduce fresh air or remove contaminated/stale air from work areas, tanks and confined spaces.

Portable Design

Compact construction, carrying handles and optional wheels make the units easy to transport between work locations.

Flexible Ducting

Fans can be configured with flexible ducting for directing fresh air into a confined space or extracting fumes and vapours from a specific location. Some industrial models are supplied with 5 m ducting.

Hazardous-Area Options

For oil & gas and other potentially explosive environments, ATEX-certified ventilation fans are available. Certain certified models are specifically designed for tank degassing and extraction of chemical vapours.

Air Supply & Extraction

Depending on configuration, the same type of equipment can be used for:

Fresh-air supply

Fume extraction

Tank ventilation

Tank degassing

Heat removal

Confined-space ventilation

Vapour dilution

Typical Applications

Storage tank ventilation

Tank cleaning operations

Vessel entry

Confined-space ventilation

Chemical vapour extraction

Maintenance operations

Marine & Offshore

Ship-tank ventilation

Cargo tank cleaning

Engine-room ventilation

Marine vessel maintenance

Confined-space operations

Industrial

Factory ventilation

Welding-fume extraction

Waste-storage areas

Safety Considerations

For confined-space and hazardous-area applications, the fan must be selected according to the atmosphere and applicable site requirements.

Important: A conventional electric fan should not be used in a potentially explosive atmosphere unless it is specifically certified and suitable for that hazardous area. ATEX-certified portable fans are available for such applications.

Optional Accessories

Flexible ventilation ducting

Duct storage bags

Tank adapters

Reducers

Extension ducts

Protective guards

Carrying frames

Wheels

Speed controllers

ATEX-certified motors/fans

Airflow monitoring

Remote-control options

Driscoil's listing also identifies standard configuration, custom modifications, data logging/monitoring and remote-operation features as configurable options.
