What is a 4 inch Panel Fan ?

Originally, Panel Fans were developed for?extracting air. That’s why they were placed inside a wall. However, due to their easy installation options and the broad range of standard fans, our Multifan and EMI Panel Fans can also be used for various circulation applications.

A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner.

Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used

Panel fans are the?ideal solution for applications?that require high efficiency and quiet operation. Applications for Continental Fan’s panel fans include condensing units, process and general ventilation, power plant ventilation, foundry ventilation, warehouse ventilation, factory ventilation, and much more.

Advantages

4″ inch Rolycab fans which have Sleeve bearings are less expensive than most ball bearing designs and require less maintenance and installation time.

The most common fans found in PSUs today use a sleeve bearing, which has a decreased lifespan compared to the other two bearing types mentioned.

Fans utilizing a sleeve bearing cost less and deliver low noise output levels, especially at lower speeds, compared to fans that use ball bearings

Application of 4 inch Exhaust Fan

The fans are mostly used in the sectors of air conditioning, ventilation and heating (HVAC). Their main functions are?to renew the indoor air replacing stale air with fresh air or increase air circulation for ventilation or cooling.

As consumers demand smaller, faster computer systems, OEM design engineers race to create systems with compact, more powerful microprocessors and chipsets.

However, these compressed designs provide engineers with a new enemy heat. In minutes, densely packaged microprocessors or compact electronic systems can generate enough heat to destroy years worth of work.

Difference between Sleeve bearing & ball bearing

Another factor that can impact fan longevity is fan mounting. Fans can be positioned horizontally, or shaft center line parallel, or perpendicular to the ground. Fan orientation does not affect the longevity of ball bearing fans.

Ball bearing fans can be mounted in any position because preloading of the bearings is built in during the bearing manufacturing stage.

Preloading describes the procedure by which manufacturers build an initial side load, such as a spring or a wave washer against the balls, into the ball bearing. This makes the bearing more durable.

In comparison, sleeve bearing fans can maintain life spans comparable to their ball bearing counterparts when the sleeve bearing fans are mounted in vertical positions.

However, when sleeve bearing fans are mounted in any position other than vertical the fan?s life span decreases.

When selecting a bearing type, the design engineer must consider the orientation for which the fan will be mounted. If the fan needs to be mounted vertically, the engineer might choose a sleeve bearing fan.

However, if the fan is mounted in any orientation other than vertical, the engineer may want to select a ball bearing fan. A design engineer needs a reliable fan that will maintain system cooling and protect against system meltdown.

Most engineers believe that a quality axial fan is the answer to this threat. Yet, many engineers debate over which bearing to use in the axial fan.

Since bearing type is a crucial factor in determining an axial fan?s reliability, it is important that the design engineer choose the right bearing for the right application.
