The Standard Series (STD2) of Mars Air Doors offers a variety of lengths to provide an environmental barrier to your space of up to 12 feet, while protecting your space from insects up to 10 feet. The STD2 has a stronger motor and is a little louder than the LoPro (LPV2) series, but its 1/2 horsepower motor may be better suited for your space.

This unheated, 208/230 volt, single phase air door is 10 5/8" tall and comes in a variety of lengths from 36" to 144". The STD2120-3UD-OB is 120" long and includes three, 1/2 HP motors. Some sample installation applications include shipping/receiving doors, customer entrances, cold storage rooms and many more. Ideal installation height is 8' - 12' for the STD2 series.

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 to meet your design aesthetics. Units 36" to 48" long feature a single motor, units 60" to 96" feature a 2- motor design and units 108" - 144" have 3 motors. Each motor boasts 1/2 horsepower. 3-motor units (108" - 144") also require a Motor Control Panel (MCPA-3UD). The Standard Series each ship as a single unit, regardless of length.

The profile of the STD2 is low profile for its power.

The chart below lays out the available lengths for the 208/230V, unheated electric STD2 Series of air curtains. 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, 208/230V unit include:

  • Door Limit Switch 99-014 - Combination mechanical switch, 250v, 1HP Max
  • 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.

Additionally, a motor control panel and a separate relay or relay with time delay is required to operate the STD2 air curtain. The motor control panel is a separate, externally mounted control panel and is available for each size Air Curtain. The MCPA-1UD is specific to single motor units (36" - 48"), MCPA-2UD for 2-motor units (60" - 96") and MCPA-3UD for 108" - 144" unit (3 motor units).
