What is a fan shroud?
Water flows through the radiator, which helps keep it cool, but when the radiator is not being cooled by travelling air, the fan is there to pull or push air through the radiator, aiding the cooling system of the car.
The shroud keeps the radiator working more efficiently by channelling the air through the whole radiator and not just through the spot where the fan sits.
To summarise, the fan draws air through the radiator whilst the fan shroud distributes that air evenly through the radiator core.
Can I use a fan without a shroud?
You could, but you probably should not. Having a fan with no shroud would still have a cooling effect on the radiator; however, under heavy engine load or being stuck in traffic, the loss of efficiency could be enough to cause overheating of the system.
Should I upgrade my fan and shroud?
The fan shroud, whilst also gaining efficiency, reduces turbulent air going through the radiator, reducing the noise throughout the system.
Upgrading to a slimmer fan and shroud set-up will also gain you as much room as possible in the engine compartment. Gaining room will help when doing maintenance jobs on your car, and having more space between engine components allows air to move more freely, which helps keep parts at a cooler temperature.
Why should I get an upgraded fan and shroud?
Here at Exoracing, we have spent a lot of time developing our high flow series of fan shrouds. They are designed to work with OEM and aftermarket radiators, making installation straightforward.
You can build your car to whatever spec you need. The shrouds and fans are all designed to be as slim as possible whilst still having increased efficiency, which leaves you a lot of room to work in the engine compartment and as much space as possible for airflow.
With our shrouds and supplied SPAL fans, you can expect to see a CFM increase which is enough to keep the highest-powered cars operating at optimal efficiency.
Our fan shrouds combined with the SPAL fans are designed primarily for fast road and track applications. The design of the fan shroud itself allows maximum air to pass through the radiator whilst remaining lightweight, solid and stylish.
