This is why our side intake is more effective at cooling!  

 Drop Ceiling Heat Exhaust Fan

  73 Degree Office, I.T. & Server Rooms, w/o Xtra A.C. units - YES 

The  "Axe" removes only the hottest air @ the ceiling,horizontally, with the side intake. The intake area drops 1" below the ceiling grid. Doesn't "tunnel" into the center of the room,removing the cooler air @ the center & floor area.The Cooler air @ the lower parts of the room remain. There is a 5 - 6 degree difference between the floor & ceiling.The heat is exhausted,the thermostat turns the system off. The temperature of the exhausted air is the same as air at ceiling of main office; just like your HVAC system.  Based on 75 degree  adjacent office room temperature.

The "Axe" is thermostat controlled (mounted on the system intake plate) to only exhaust the lightest, hottest air, down to your desired temperature, usually about 73 degrees. The Switched "Axe" creates the same wide radius intake, at the ceiling, in a wall switched application. Low clearance systems (12" or less above ceiling grid) are also available. See under PRODUCTS 

Fits standard 2 x 2 grid. Less than 10% of the operating cost of Air Conditioning with zero maintenance, less initial & installation cost. The reason is, the AXE only has a high efficiency, commercial fan, to remove heat horizontally, where it's hottest & a thermostat to control it.  AC units have compressors, fans, etc. Look at the power consumption for the AC unit you are considering & compare to the AXE. We only remove the hot air at the ceiling, A.C. units mix cool air with hot air, not very efficient. Removing only the hottest air is much more efficient. The SC-6H, 435 cubic feet/min. only uses 115 watts of 110 volt power.

IE: 20' x 10' room down to 73 degrees in under 2 minutes - using SC-6H system. 75 degrees in next office. 20' x 10' x 8' high = 1600 cubic fee. 32 square inch grill installed, lower part of door. Exhaust system thermostat set @ 77 degrees. Heat accumulates, across the ceiling, exhaust turns on, heat is removed, temperature drops to 73 degrees,at normal thermostat height ( about 60" from floor) Exhaust turns off (thermostat control). Waits for more heat to accumulate. 

 BUT ! if your office is weekend HVAC SHUTDOWN, you may need an portable A C Unit. Our system will also extend the life of your extra A.C. unit.

Our efficiency @ cooling is remarkable. Proven Server Room Cooling, Data Center Cooling, I.T. Room Cooling, Re-balancing Office Heat, Restaurant Kitchen Cooling, ETC. Hot Air Axe's are galvanized steel with commercial grade fans & thermostat. Built to LAST & be repaired 20 years down the road, the old school way

Cool Air Intakes -Maximum Cooling Efficiency

 While the thermostat controls the Hot Air Axe, the hot air exhausted, needs to be replaced with cooler air, from main office, or cooler adjacent area. Extra A.C. unit for isolated rooms, weekend A.C. shutdown in large offices, may be needed. Exhaust cycle is about 25% of room volume, System does not run continually.

6" hot air axe = 30 sq inches of free cool air intake from the next room,8" hot air axe needs 50 sq. inches of vent, 12" hot air axe requires 100 sq. inches of intake. Two louvers or grills (size appropriate) are included with each Hot Air Axe. Grills & intakes should be closest to floor level as possible(coolest air).

6" systems cool 500 sq. ft.

8" systems cool 900 sq. ft.

12" systems cool 1500 sq. ft.


Existing louvers in wall or door should be blocked to the above size, opening @ floor level. Bottom of doors cut off.  Can't modify doors or walls? Inexpensive replacement doors from the home improvement store to modify & replace original, at lease's end. Ceiling mounted room coolers are available.

   Zero drains,water leaks,refrigerant leaks,floor space,maintenance calls,downtime,10% of A.C. operating cost.

                       Fully assembled,10 year warranty, 90 day trial

  The Hot Air Axe Exhaust system will exceed your room cooling expectations!
