The AES Advantage

The following is a compilation of other brands and may or may not apply to a particular brand. The following applies to our IND Industrial Air Curtains. When comparing air curtain brands for purchase, make sure you are comparing apples to apples. A lower price can also result in:

  • Performance that falls short of your requirements
  • Higher installation costs
  • Higher maintenance costs
  • Shorter operating life

The joy of receiving the lowest price is very often offset by the pain of subsequent costs!

AES -The “Custom Built” Air Curtain
The Competition – Ind Series
Frame Tubular steel
  • Absolute rigidity with no deflection to 30 ft. in width
e Tubular aluminum or angle iron
  • Units over 8 ft. sag, throwing blowers out of alignment. Decreases life. Increases maintenance.
Exterior Enamel on galvanized steel – totally enclosed
  • Attractive appearance, corrosion resistant – All components are totally enclosed with the air curtain
e Galvanized Steel – Motors outside case
  • Poor ascetics. Even in a warehouse, appearance counts
Motors Belt drive, totally enclosed
  • Long life, dust free. Infinite velocity adjustment for different heights of opening. AES uses a velocity of 300 ft./min per ft. of height
e Direct drive, open motors
  • Motors take in dust, reducing life. Velocity is pre set by RPM. One velocity does not fit all heights.
Blower Shaft Single shaft per blower
  • Ease of maintenance. Individual blowers may be easily replaced
e Multiple blowers per shaft
  • All blowers must be replaced if one is damaged or fails
Shaft Coupling Vibration dampening coupling between each blower None.
  • Smooth operation. Vibration from one blower is not transmitted throughout the air curtain. Ease of maintenance.
e Single shaft for multiple blowers
  • More change of misalignment. Difficult, expensive maintenance
Air Intake Front
  • No obstruction to air intake
e Top
  • Air intake is restricted when overhead door is raised
Discharge Vanes 3 rows of 2 ft. long, AES designed Vanes
  • Extruded aluminum. Infinite adjustment of air flow for individual applications. Every vane can be individually adjusted. ‘Tear drop’ shape provides maximum efficiency with laminated air flow.
e Flat, generally all vanes must be pointed in the same direction
  • No adjustment for individual applications. No lamination of air flow.
Plenum 5″ deep full length
  • Plenum allows air to mix between blowers largely eliminating dead spaces in the air flow.
e Direct discharge
  • The space between blowers is ‘blanked’ off causing a large V shaped area between each blower with no air flow protection against the intrusion of cold air.
Control Panel AES Exclusive one cabinet panel.
  • Panel contains on/off switch, motor overload protection, disconnect and connection to door operated micro switch which is also included
e No controls or separate components for each function
  • Added cost. Added mounting space required
Mounting Two methods
  • May be mounted by suspending from ceiling joists or by knee braces
e Single method
  • If the one method does not fit, the cost of the installation is greatly increased
Design Custom design for every application
  • The air curtain you receive will ‘work’ in your application. It has been custom designed to do so!
e Off the shelf
  • A one size fits all philosophy. One size does not fit all! Try this concept by towing a large trailer with a ‘Smart Car’.
Delivery Four to six weeks
  • The air curtain you receive will ‘work’ in your application. It has been custom designed to do so!
e One Week
  • You receive a cookie cutter design air curtain
