1. ‘A little bit about the CowKool fan …’ ‘With conventional fan motors you have a rotor located inside the electric motor… ‘ An external shaft then has a fan blade pressed on it.’ ‘One of the highest failure and replacement cause of conventional fans is the fan blade getting out of balance.’ … and a stator located on the outside of the electric motor.’

2. ‘A little bit about the CowKool fan …’ ‘The CowKool fan motor is just the opposite.. The stator is built inside the motor … ‘… with the rotor built on the outside.’

3. ‘A little bit about the CowKool fan …’ ‘The shaft is completely internal …’ … and sealed at both ends with moisture resistant bearings.’ ‘Moisture getting inside the motor is also a high failure and replacement cause of conventional fans.’

4. ‘A little bit about the CowKool fan …’ ‘The CowKool fan blades are made of aluminum die-cast and are actually an integrated part of the rotor … turning with the rotor.’ ‘This unique fan-motor design provides for perfect life-time trouble-free fan blade balance.’

5. ‘A little bit about the CowKool fan …’ ‘All electric motors generate heat. The CowKool fan blades also act as a heat sink dissipating heat generated by the motor. This significantly extends the operating life of the fan motor.’

6. Built to last …. ‘Each fan is individually protected with an overload protector.’ This provides maximum protection from power surges (very common in rural areas) This also serves as an individual ON/OFF switch for fans when needed ‘For safety each CowKool fan comes with a front and back grill.’

7. Built to last …. ‘The CowKool fans are by far the best fans that I’ve seen on the market. I’ve had my fans installed over 32 years with very little problems.’ Isac Gal Kibbutz Ashdot Yaakov Ichud Israel

8. Built to last …. ‘I’ve had my CowKool fans in now for 20 years. I’m now rebuilding all of the barns and will stay with the CowKool System. My summer time milk production is the same as my winter time production. I’d recommend this system to any dairyman.’ Uri Gil Kibbutz Bachan, Israel

9. Built to last …. ‘We tried other fans in the past but had a lot of problems. We’ve had our CowKool fans in now for 25 years and what a difference! No other fan that I’m aware of comes close to the quality of the CowKool fan.’ Eli Schiller Kibbutz Givaat Haim Ihud, Israel

10. Built to last …. ‘I wish all of the equipment on my dairy was made with the quality of my CowKool System. I’ve had over 25 years of very reliable service with my fans.’ Asor Baheer Kibbutz Ein Harod Ihud, Israel
