Small and Medium Vans

Flettner ventilators are widely used on fleets of vans and are generally specified for three major reasons:

(1) To extract fumes or stale air from vehicles (for driver and passenger comfort and for health and safety reasons). This applies especially to vehicles carrying gas cylinders, inflammable liquids or chemicals.

(2) To minimise condensation within vehicles. This applies especially to situations where vehicles are frequently stationary or where wet overalls and equipment have to be stored in the vehicle. The installation of the ventilators in this case significantly reduces the damage to equipment and the deterioration of the vehicle's interior through water build up and mould.

(3) To reduce the temperature of vehicles during summer time for operator comfort and for the protection of equipment or perishable goods. (The daytime interior temperature of unventilated vans even in temperate latitudes during the summer months is typically 100ºF in the sunshine or higher still whenever the van is stationary).

4x4s / All Terrain Vehicles

Flettner ventilators can be used to minimise the condensation problems associated with 4x4 vehicles which are often used in damp environments and which are often left stationary for long periods.

The continuous operation of the Flettner ventilator helps to prevent the build-up of damp and the consequent damage of the vehicle fabric and equipment.

People Carriers and SUVs

Flettner ventilators are suitable for providing additional ventilation in people carriers and SUVs in order to create an additional flow of fresh air through the vehicle and to assist in extracting heat and smoke and in reducing condensation problems.

Buses and Minibuses

Flettner ventilators are widely used on bus fleets to provide forced air extraction at the rear of the vehicle in order to create a throughput of fresh air and reduce excessive heat.

The ventilators help to extract cigarette smoke and to provide a more comfortable environment for the travelling public.

In addition the use of forced air extraction greatly reduces the amount of condensation within the bus.

Flettner ventilators continue to operate in a slight breeze even during the periods when the bus is stationary and thus provide extra help in minimising condensation problems.

On coaches Flettner ventilators are also fitted to provide extra ventilation for toilet compartments.

Ambulances

Flettner ventilators are suited to use on ambulances which for the majority of the time are stationary but where continuous ventilation is desirable in order to reduce the interior temperature in readiness for use of the vehicle at any time.

Agricultural Vehicles

Flettner ventilators are suitable for the cabs of agricultural vehicles in order to combat condensation and dampness.

Animal Carrying Vehicles

Flettner ventilators are ideal for animal carrying vehicles such as dog vans, horse boxes, pet ambulances, and livestock vehicles. The ventilation provided is continuous even in the lightest of breezes when the vehicle is stationary without any drain on the vehicle's battery. It should be noted that in those circumstances where a vehicle is otherwise air tight an additional air inlet such as a grille should be fitted in order to provide an air path through the compartment.

Caravans and Recreational Vehicles

Flettner ventilators are ideal for caravans and recreational vehicles providing year-round ventilation to combat heat, water condensation, dampness and mould even when the vehicle is stationary without any drain on batteries.

Glider Trailers

Flettner ventilators are widely used on glider trailers to provide constant ventilation and thereby to prevent heat and condensation damage to the gliders.

The fact that the trailers are often left parked for long periods of time makes the Flettner ventilator ideal in that it provides continuous forced air ventilation even in a slight breeze.

Vehicles for the Disabled

Vehicles that have been converted to carry people in wheelchairs often suffer ventilation problems due to the high roof profile which can create a 'dead air' space or due to the presence of extra glass panels which can lead to excessive heat build up.

A Flettner ventilator fitted to the roof of such vehicles provides a path of forced air extraction which greatly reduces the heat build up and discomfort for the driver and passengers.

Additionally because the Flettner ventilator continues to operate even when the vehicle is parked, the vehicle's interior temperature is maintained at a more acceptable level ready for use.
