J&D prides itself on being

completely transparent when

it comes to performance data.

The Magnum 58” Exhaust Fan was tested in an

accredited AMCA Air Test Chamber, as well as at

Bess Lab. When creating the Magnum 58”

Exhaust Fan, it was our goal to be the best fan in the world. We researched our competitor’s

fans’ performance data and the results are in.

The Magnum 58” Exhaust Fan exceeded Bess

Lab’s testing capabilities at 0.0”SP – 0.10”SP. We

then put our fan in an AMCA accredited Air Test

Chamber, so we could get some kind of idea what

the Magnum 58” Exhaust Fan can do outside of

Bess Lab’s testing capabilities. Our CFM blows all

our competitor’s fans away.

What happens when you only apply a certain percentage power to the Magnum 58” Exhaust Fan? You save energy! This is

especially beneficial for minimum winter ventilation. Still get the airflow you need, but save on your energy bill.

Cone• Deep for superior performance • Multi sections makes for ease in handling when installing as well as reduced shipping

Damper Doors• Edged with magnets and 360° of rubber seal to minimize air infiltration• Dual tension springs • Blow molded durable poly will endure even the harshest conditions

Magnum 58” Exhaust FanThe Magnum 58” Exhaust Fan uses a maintenance free direct drive permanent magnet motor. It eliminates the need for greasing

bearings and changing belts. The housing is made of strong poly while the frame is all stainless-steel preventing rust and

corrosion in any environment. The complete fan includes durable poly damper doors that seal out air and light when closed.

The Magnum 58” Fan is designed to operate in the full range from minimum ventilation to maximum power using basic 0-10 volt

control signal which eliminates the need for smaller fans. Because of the high performance of the Magnum 58”, you’ll use 25%

fewer fans on your next project making it your most economical choice.

THE J&D DIFFERENCEShipping

The Magnum 58” Exhaust Fan is easy to assemble, and it’s

packaged in such a way to reduce shipping costs. You can get

up to 64 fans per truckload. When ordered in large quantities

and bulk packaged, get even more fans per truckload!

When ordering 64 fans or less, each fan will come in it’s own

individual box, knocked down. This makes installation a breeze

by having all pieces and hardware in one location for each fan.

Mounts flush to the wall

The Magnum 58” Exhaust Fan easily mounts in the

rough opening and flush with the interior of the building.

It can also be mounted in a 2x4 or 2x6 wall.

• Rough Opening = 65.5” x 65.5”

With advances in technology come advances in ventilation. As the costs of

technology have come down, it has made it more reasonable to utilize these

technologies in ag ventilation. As the technology advancements sweep through

the agriculture, horticulture, and commercial/industrial markets, J&D wants to

make sure you know what a permanent magnet motor is and the advantages of

this type of motor so you can make the best decision for your operation

Permanent Magnet (PM)Instead of using windings on its rotor, a PM motor uses permanent magnets, meaning the rotor is

magnetized already. J&D’s PM motors are driver integrated and efficient. Because they are driver

integrated, soft starts are ‘included’. You do not need a VFD on a PM motor. They are easy to speed

control and it runs at a constant speed regardless of load. Our PM Motor also comes with surge start.

For the first 10 seconds the fan will run at full power. This is so the damper doors will come open on the

Magnum fan. After the surge start, the fan will run at the speed in which you want it to run. There are

three ways to control the PM motor, 0-10 volts, 4-20 mA, and manual on/off. We can use this efficient

type of motor with our largest fans. We consider the PM motor the best motor for your operation.

What is a Permanent Magnet (PM) Motor?

Advantages of PM Motors1. Precise and Consistent Variable Speed Control Regardless of static pressure, wind, and other environmental

variables, the motor will run at a constant speed. More or less

power will be applied to the motor so outside factors do not

compromise set speeds.

2. Maintenance Free No belts, pulleys, tensioners, bearings or gears! Don’t spend time

changing belts, or lubricating bearings. Just set it and forget it.

3. Extremely Efficient PM motors run cooler to the touch and will not overheat and

burn out. When running at lower speeds, the energy efficiency

actually increases, effectively saving on energy costs.

4. Increased Motor Longevity Because of the PM motor’s lack of moving parts, there is a

lot less parts that will wear over time. The motor runs cool,

also increasing longevity.

5. Less Fans With speed control capabilities, you won’t have to have

a combination of fan sizes to operate minimum winter

ventilation and maximum summer ventilation. The PM

motor allows you do to both with the same fan. Purchasing

additional smaller fans is not needed.
