‘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.’
‘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.’
‘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.’
‘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.’
‘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.’
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.’

‘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.’

‘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 SchillerKibbutz Givaat Haim Ihud, Israel

‘This air velocity data was measured on a conventional 36-inch, ¾-hp, 13,000 cfm fan.’ Because of the limited airflow that conventional fans offer you can
easily see why so many of these conventional-type fans are required.’
