The floor vent for vans – large version ensures reliable ventilation of the cargo area, especially when transporting gas cylinders, damp materials, food, or plants. Its generous opening of 120 cm² allows for very efficient air circulation, which effectively reduces heat, moisture, and unpleasant odors.
Large floor vent for vans
The large version of this floor vent is ideal for vehicles that require particularly strong airflow. It is made of robust ABS plastic and is ideal for commercial applications where a permanently stable interior climate is important. The vent can be installed with a hole saw (Ø 85 mm) and is securely glued to the vehicle floor panel.

Installation of the floor fan
The floor vent can be installed outside the loading area and is glued directly to the floor panel. It is installed through an 85 mm opening made with a hole saw. For lasting protection of the cut edge, we recommend treating it with zinc spray and underbody protection to reliably prevent rust formation and water ingress.
Legal requirements for the transport of gases
The Federal Ministry of Transport stipulates adequate ventilation when transporting gases. According to the German Road Transport of Dangerous Goods Regulations (GGVS) and information sheet DSV 0211, transporters must have two free ventilation openings – one in the roof area and one in the vehicle floor. Both openings must have a cross-section of at least 100 cm² and must be positioned diagonally opposite each other.
The large floor vent easily meets these requirements with its cross-section of 120 cm² and is therefore ideal for use in the transport of dangerous goods.
Why a large floor vent is the best choice for many types of transport
While smaller floor vents are usually intended for light ventilation tasks, the large version provides significantly more airflow. This dissipates heat more quickly, prevents moisture from stagnating, and keeps the cargo area noticeably drier and less odorous.
- Ideal for permanently ventilated cargo areas
- Prevents heat build-up in the lower part of the vehicle
- Particularly effective for damp and odorous goods
- The perfect addition to roof or side wall ventilators
- Meets all legal ventilation requirements for gas transport
Comparison: large floor fan vs. other fan types
The large floor fan differs significantly in terms of performance and application:
-
Large floor fan: maximum ventilation in the floor area, very large cross-section, ideal for hazardous goods and damp loads.
-
Small floor fan: more compact, but lower air flow.
-
Single or duo floor ventilators: more flexible size, but not always suitable for large volumes.
-
Roof ventilators: remove warm air upwards – ideal in combination.
Together with a suitable roof fan, this creates a particularly efficient two-zone ventilation system.
FAQs about the large floor fan
What applications is the large floor fan suitable for?
It is ideal for transporting gas cylinders, damp materials, food, plants, and all goods that require continuous ventilation.
How is the large floor vent installed?
The fan is inserted through an 85 mm opening and then securely glued to the base plate.
Does this floor vent meet GGVS requirements?
Yes. With a cross-section of 120 cm², it meets the requirements for floor openings for gas transport.
Can the floor vent be combined with roof vents?
Yes, the combination of floor and roof ventilators results in a particularly efficient ventilation system, as warm air escapes at the top and fresh air flows in at the bottom.
Is ABS plastic suitable for continuous use?
Absolutely. ABS is robust, weather-resistant, and ideal for continuous vehicle use.
