Importance of Buying a Centrifugal Air Mover

Centrifugal air movers are ideal for drying applications and are regularly utilized by experts in the water damage restoration industry. They can be utilized to blow away dust during demolition or accelerate drying times for drywall and paint jobs – expediting all of those procedures that consistently take up your time.

This sort of air mover makes an exceptionally focused airflow by routing the air through a series of ducts, dampers and different segments. The Inside of these units appears as a hamster wheel, which is the reason these fans are known as squirrel cages. Read on to know more.

Why should you choose a centrifugal fan?

Centrifugal fans (or spiral fans) are comprised of a fan wheel (impeller) driven by a motor that pivots in a stator appended to the wheel. This stator has two openings: the first one supplies the focal piece of the impeller with liquid, which penetrates by vacuum and is blown by centrifugal effect through the second orifice towards the edge.

There are two types of outward fans: forward bended fans and reverse bended fans. Forward bended radial fans have a “squirrel cage” and a number of sharp blades extending from 32 to 42 units. Their productivity is 60 to 75%. Reverse bended centrifugal fans have a proficiency of 75 to 85%, with various units running from 6 to 16.

The overpressure is higher than that provided by a propeller fan; these fans are a lot more suitable for long circuits. Apart from this, they offer an advantage regarding noise level: they are much quieter.

Things to consider

Environment

The environment where the machine works should be considered to pick the correct blower-motor combination.

Outdoors

Consider a Totally Enclosed Fan Cooled (TEFC) electric motor on direct drive units, or a belt driven unit with an included climate spread.

Grimy or Dusty Environment

A TEFC engine is best for longer life and ideal productivity.

Corrosive Environment

In wet, damp conditions, a stainless-steel blower is suggested, ideally with a stainless wash-duty motor.

Hazardous Environment

Consider a non-sparking blower, for example. This is a radial or high-pressure blower.

Airflow (CFM)

CFM or cubic feet per minute is the estimation of how much air is moved by the machine in 1 minute. Remember: a higher torque doesn’t mean a higher CFM. For the most part, you can expect that axial air movers should have a CFM rating of at least 3000. Centrifugal air movers regularly run 2400-2700 CFM.

Motor power and speed

While picking an air blower, you can consider the engine that will control it which could extend from a ΒΌ HP engine to 1 HP engine. To begin with, you’ll have to consider where you’ll be utilizing the air mover.

The Takeaway

Unlike your standard fan, centrifugal air movers work by giving a consistent blast of air that you can direct on a particular spot. As a result, you can use them for a variety tasks, including drying wet surfaces, improving the airflow and preventing different types of machines from overheating.
