Here's what the Pros say...
“At first I had my doubts with all of the outstanding claims being made about the “new” fans. I’ll admit, the Gale Force truly impressed me and exceeded my expectations. A real test to new equipment is how well my technicians adapt to using new technology. Simply stated: They loved them. Proof positive is how they all grab the Gale Force fans, leaving my standard air moving equipment behind. Another feature that the technicians noted is the stacking feature - it actually works! It is a great benefit when loading our already full cube vans.”

force air movers




Matrix Carpet Cleaning Supplies

The GALE FORCE has become the #1 selling Minimum Amperage Air Mover and the first choice of Professional Restoration Contractors when the job demands the best!
The Gale Force is the only air mover in the industry designed by restoration contractors for restoration contractors.

The result of months of in-depth customer focus groups, state-of-the-art engineering and rigorous field tests, the Gale Force offers an unbeatable combination of maximum airflow, minimum amperage and performance pitch for superior drying power.

Maximum airflow. With 68% more airflow than typical air movers, you'll see the difference the very first time you use the Gale Force.

Minimum amperage. At a mere 2.5 amps, the Gale Force allows you to run more units on the same circuit, thus maximizing total drying power on the job.

Performance Pitch. Holds the unit at a precise angle and pitch that produces a drying area over twice the size of the competition.

Hear what these industry experts have to say about the Gale Force...

 These industry experts agree that Gale Force is the only choice when nothing less than superior drying ability will do.

"Chuck Dewald and the Dewald Drying Institute (DDI) conducted axial air mover research and testing for Dry Air Technology. The purpose of this research was to determine the optimum performance positioning of axial air movers. The results showed that positioning the Gale Force set up at a 30 degree angle and pitching the unit down 9 degrees (1.5 inches) produced the largest drying area. The Gale Force with the Performance Pitch Retro Kit produced a drying area more than twice as large compared to the best performing competitive axial air mover."
-Chuck Dewald III, August 2004

"Finally someone has listened to ol' Chuck. I've hooped and hollered for years that our two major problems in the field are heat and finding the power to handle the needed amount of equipment on any water loss. The Gale Force can eliminate both of these problems and many more by operating at minimal amps, giving off less heat, and generating much more actual CFMs to dry any structure much faster. The Gale Force is and will be the fan of the future."
-Chuck DeWald, Emergency Vortex Drying School

The Performance Pitch: New technology that makes the Gale Force even MORE effective than ever before!
In their continual push to raise the bar in the world of high-speed drying, Dry Air Technology, the makers of the Gale Force, in combination with industry experts like Chuck Dewald have taken the already revolutionary Gale Force design and given it legs! Or feet to be more precise. It’s called the Performance Pitch and you won’t believe what a leg up it gives the Gale Force.

In most drying procedures, airflow is directed across wet surfaces to accelerate evaporation. The most common method used involves air movers set up on the floor at an angle to the wall and spaced every 10 to 14 feet. This particular approach, originally developed by Chuck DeWald and first taught in his drying school, is critical to the "In Place" or "Top Down" drying method taught in IICRC "Applied Structural Drying" (ASD) classes.
New Performance Pitch Air Mover

Unfortunately, the performance characteristics of the centrifugal carpet dryers normally used to provide this airflow does not efficiently match this application. It’s a job more suited to the low amp, high volume airflow features of axial fans. The Gale Force Vane Axial Fan from Dry Air Technology was the first low amp, high volume, axial airmover created specifically to perform this drying function. Driven by the desire to maximize axial performance results, Dry Air Technology partnered with DeWald Drying Institute to analyze the factors that impact drying efficiencies of axial air movers.

Initial testing revealed the fan to wall angle and the pitch of the fan to the floor affected drying results. In order to determine the ideal angle to the wall, fans were placed at angles from 0-55 degrees. Testing was conducted in a 12 x 14 room with the fans placed seven feet from the corner of each wall. Air velocity (feet per minute) readings were taken at one foot increments where the floor met the wall and a second set of readings were taken at the floor 1 foot from the wall.

After the optimal angle was determined, the pitch of the fan was investigated. Fans were placed at floor pitch angles ranging from 0-2.5”. Velocity readings were also taken in the same manner.
Next, the actual drying area was determined, testing competitive fans against a standard Gale Force and a Gale Force with the new Performance Pitch modification. Then the actual drying area was measured in square inches.

Wall Angle Tests
The highest velocities over the test area were found at 25-35 degree angles. Placing Gale Force axial air movers at a 30 degree angle will maximize the drying performance of the unit. This contradicts the previous belief that air movers should be placed at a 45 degree angle to the wall.

Fan Pitch Tests
Air movers were positioned at a 30 degree angle and various inclines from 0-3”. The highest overall velocities were achieved using a 1.5” pitch. Through their findings, Dry Air Technology determined that this precise pitch should always be implemented, therefore prompting the Gale Force Performance Pitch design.

Drying Area Tests
The actual drying area achieved is your ultimate objective. In this test, the carpet was soaked and extracted. The drying area was measured after 30 hours. The Gale Force with its new Performance Pitch produces a drying area over twice the size of the competition.

Try the new Performance Pitch out for yourself and see how much more quickly you can dry out a soaked room. When you’re working with the industry’s best it’s easy to see the difference. Feel the Performance. Feel the Power.
