Studies have shown that in the typical commercial/industrial building, heat rises at 3/4 degree Fahrenheit for each foot of vertical height. A building with a 20′ ceiling would typically be 15 degrees Fahrenheit warmer at the ceiling than at the floor.

It has been proven in countless applications that for every one degree Fahrenheit of temperature that is brought down from the ceiling to the floor (until equalization) results in a conservative 1 1/2- 2 % savings in energy usage. Additionally, we have just added to the life of the ballasts in the ceiling light fixtures.

A receiving area of a store had an ongoing 15 degree Fahrenheit difference between their 22′ ceiling and the floor. After the installation of the Air-Row F-18 fans the ongoing difference is now 5 degrees Fahrenheit. The ambient temperature was 45 degrees Fahrenheit.

This chart can be used to depict the amount of heat moved from a warm ceiling area to a cooler floor area using our destratification fan.

*Figures are based on heat delivered by one fan rated @1250 cfm velocity
Sensible Heat (BTUH)=CFM*1.08*Delta T

400 cfm=1 ton of cooling (wind chill effect)
An F-18 can equate to 1 ton of cooling in terms of air movement.
An F-18 dual can equate to 2 tons of cooling in terms of air movement.
An F-18 quad can equate to 4 tons of cooling in terms of air movement.

12,000 BTU/hour= 1 ton of refrigeration and/or air conditioning

Consider the Air-Row fan if any of the following are a concern:

•  I need the air from the ceiling to reach the floor.

The Air-Row fan will direct a column of air no wider than 3′ from as high up as 40′ to not only reach the floor, but warm the floor as it spreads covering around 2500 square feet. Our ceiling paddle fans will mix the air from the ceiling. As it approaches the floor it will spread and gradually rise back up to the ceiling.

We are not anti-paddle fans as we have been manufacturing a complete line of fan and other air moving and treatment products since 1981.

• I have a congested ceiling configuration and narrow aisles.

The Air-Row fan is a 12″w x 12″d x 18″L. The fan can fit into tight spaces among ceiling joists, beams, and duct runs. The total hanging weight is 12 pounds per Air-Row fan and presents little stress load problems.

• There is a limited amount of available power at the ceiling.

Each Air-Row fan draws 1 amp and 17 running watts. The Air-Row fan uses the equivalent power of a 60 watt light bulb.

The Air-Row fan is positioned where it will deliver air from the ceiling to where it is really needed at the floor.

We can control the speed of this air with either a hard-wired speed control at the floor level or with a remote control that can be controlled on/off and up/down at the floor.

We can control the timing of the operation of the Air-Row fan. With the temperature control option, the Air-Row fan will operate only when the ceiling temperature is within a preset temperature range. We also have the fire-safe option. The Air-Row fan will automatically shut off when the temperature at the ceiling reaches 135 degrees Fahrenheit.

We can control the volume of the air coming down to the floor by clustering the Air-Row fans in a dual bracket, or a quad bracket, etc. We also can install an UV/O3 lamp on the top of the motor bracket. Now the incoming air can rush over this lamp and be treated for airborne bacteria and/or odors, individually or in a tailored combination.
