Application of Physics

Fortunately for AirMotion Sciences, our engineers have a good grasp of science and physics and are able to apply their know-how to the design, manufacture, and performance of AirMotion AltAir™ HVLS fans. In its simplest form, the concepts involve the theories and teachings of Isaac Newton.

Newton’s Laws of Motion

Sir Isaac Newton's Laws of Motion are three physical laws that address the relationships between the forces acting on a body and the motion of the body. The laws form the basis for classical mechanics and are used to explain many aspects concerning the motion of physical objects, including air masses.

• First law: An object at rest tends to stay in rest and an object in motion tends to stay in motion in a straight line at constant speed unless acted upon by an external, unbalanced force.

• Second law: The rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction.

• Third law: To every action (force applied) there is an equal and opposite reaction (equal force applied in the opposite direction).

By understanding his three laws, and having an appreciation for thermodynamics – which is a branch of physics focused on the movement of energy and how energy instills movement (thermos means heat in Greek and heat means ‘energy in transit’ while dynamics relates to ‘movement’) –one can design air moving products like AirMotion’s AltAir HVLS fans to make the most use of the physical properties of moving air masses efficiently.

Since air has mass, once it starts moving - as inertia is overcome - the momentum of the flowing air mass allows for continuous air circulation and mixing, requires little ongoing effort to maintain. Moving more air with larger Rotatair™ blades, rather than a larger motor, enables greater volumes of air to be moved with a fraction of the energy and cost used in typical high-speed fan applications.

Using these concepts, and our VPT™ (Variable Pitch Technology), one can achieve what we call optimal CFM – Complete Facility Movement of air – using very little energy.

We have figured out the science and related physics so you don’t have to.
