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 on the STD2 Series boasts 1/2 horsepower.

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 115V, 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, 115V unit include:

  • Door Limit Switch 99-014 - Combination mechanical switch, 250v, 1HP Max
  • Controller J0021 - Commercial low voltage controller, 115V, 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.

Separate, externally mounted control panels include the MCPA-1UA for single motor units (36" - 48"), MCPA-2UA for 2-motor units (60" - 96") and MCPA-3UA for 108" - 144" unit (3 motor units) are available. Motor control panels work with Mars air curtains to automatically and/or manually start and stop the air curtain when the door opens and closes. A motor control panel is required when choosing the 99-125 surface mounted switch. Three Motor Units will not operate with the J0021 door switch. A Motor Control Panel (MCPA-3UA) is required on 3 motor units.
