Lasko 4900 vs 4905 – Performance 

Movement of air is measured in cubic feet per minute (CFM), which measures the volume that passes a stationary point in one minute. The Lasko 4900 and 4905 blower fans move air in three adjustable fan speeds. At low speed these blowers attain 250 (CFM), 300 CFM at medium and 350 CFM at high fan speed. Tests on these blower fans showed that when working on high fan speed, they blow air up to a height of 40 ft.

In the words of most users, even at low fan speed, these blowers move massive volumes of air.  Home users wanting to cool the rooms were happy with the efficiency of both blowers when operated at low speed.  The fan speed can be adjusted with a button attached to the blowers.

The two machines have a pivot tilting mechanism of up to 3150 angles. This is great as it gives the user the option of directing air to their preferred direction, either where they want to ventilate, dry, exhaust or cool.

Lasko 4900 vs 4905 – Design

The sturdy plastic casing of the Lasko 4900 and Lasko 4905 blowers serve two purposes. It protects the sensitive interior parts from damage from wet spillages, dust, and unnecessary manipulation. It also makes it easy to clean these blower fans.

The blower fans do not have filters and they, therefore, do not suck in dust and other solid particles like fur and hair. Clogging that is associated with filters is therefore not an issue, making cleaning and maintaining them much easier.  Since they use a turbine system, there are no sharp blades that can hinder cleaning of the interior parts.

To access the inside parts, all you need to do is unscrew some bolts at the base of these blower fans, slide the casing and clean your appliance. And when you finish cleaning it is easy to reassemble the blowers.

Note that failing to clean and maintain your blower fan regularly will compromise its efficiency. Most users who failed to do this later complained that their Lasko 4900 and 4905 blowers lost their strength after a while.

Four wide, well-spaced rubber feet at the base of these machines give them stability when placed on any surface. If you need to place your Lasko 4900 or Lasko 4905 blower in a busy working area like a workshop, you need not worry about it tipping over. The feet are stable enough to withstand such conditions.

These Lasko 4900 and 4905 blower fans have a power cable that can extend to a distance of 10 feet. This is an advantage since you can position it a distance away from your power socket and move it around your room or area as you wish.

The easy-grip, the built-in handle on these blower fans is made of strong chrome material to enable you to move your appliance without worrying about the handle breaking.

As mentioned earlier the color of the two blower fans is among their few distinguishing features.
