The STD2 Heated Air Curtain features an internal mounted control panel, remote thermostat with heat/off/fan settings.

The STD2 air curtain offers a cost efficient barrier that will blend in to any environment. Its durable metal construction is finished in a powder-coated obsidian black. Units 36" to 48" long feature a single motor, while units 60" to 96" feature a 2- motor design. Each motor boasts 1/2 horsepower. The Standard Series each ship as a single unit, regardless of length.

The chart below lays out all the optional lengths available for the STD2 208/3/60 air curtain. The highlighted row is specific to this item. Simply choose your length based on your installation needs. 

It is recommended that a door switch be used with the air curtain. Door limit switches automatically activate and de-activate (start and stop) the air curtain when the door(s) open and close. A controller that offers time delayed control reduces the cycling of the air curtain motors in high traffic areas (10+ times/hour). This type of controller will delay the unit from turning off when the door closes. They can usually be set from 6 seconds to up to 20 minutes. Available door switches and controllers for the STD2, 208 and 230V units include:

  • Door Limit Switch 99-014 - Combination mechanical switch, 250v, 1HP Max
  • Door Limit Switch 99-018 - Commercial Surface mounted, magnetic switch, 24v
  • Controller J0022 - Commercial low voltage controller, 208-277V, 1Ø, adjustable time delay, with commercial plastic surface mounted door limit switch (field installed)

When you add a door switch, your unit will automatically turn on when the door opens and off when it closes. Plus, it will continue running for a configurable period of time.
