Magdek CalfVent™ & Cattle Fans

Cows lungs are more critical to performance than most other farm animals. That’s why successful farmers focus on pneumonia prevention, making Magdek CalfVent™ part of their herd health program.

The last two years my calves were dropping like flies – I tried every remedy. Then I installed Magdek’s Calf Vents. Success!

-Noel McNamee, Longford

In the past many have depended on positive pressure ventilation systems; which replenish fresh air continuously; but now thousands of UK farmers have become aware of the link between productive, profitable units and ‘Environment Control’ provided by the Magdek CalfVent™.

Custom tube systems with multiple-hole layouts distribute air evenly, without creating draughts. Air change within animal housing is essential to remove aerosols that pass bacteria into animal’s lungs so we designed our moulded fan housings to outperform any other product on the market.


• Single systems up to 35m long

• Custom tube with multiple hole layouts to latest vets designs

• Special tube works even with low roof frames

• Lifetime guarantee on housing

• Moulded fan housings out perform any other product on the market

• Tube length easily adjusted with unique Magdek clip system

Changing the air conditions for all the animals in your shed is as simple as turning a dial to adjust airflow or temperature. Simple management, immediate results with minimum work.

Typically your new Magdek CalfVent™ system will serve you for 20 years or more. Invest today and enjoy the benefits of a healthy herd for many years to come.

The tube is durable enough to last years but cheap enough to replace regularly if you require.
