Air Curtain Size Chart

Opening and Mounting

Measure the finished door width, clear opening height, and actual mounting height from the finished floor to the air curtain discharge. Width usually frames the cabinet length; mounting height decides whether the opening is still in a practical range for the selected product family.

Header and ceiling clearance matter before any model comparison. A recessed header, low ceiling, uneven wall surface, exposed conduit, sign, sprinkler, or door closer can shift the project toward a different mounting style even when the width looks ordinary.

Doorway Duty

A retail entrance, delivery opening, ceiling-mounted doorway, cold-room door, and kitchen-adjacent opening should not be treated as the same air curtain problem. Retail projects usually emphasize comfort, insects, and traffic. Cold-room projects add temperature separation, condensation, frost risk, and cycle rate. Service doors add wind, dust, and repeated opening patterns.

This is where the chart connects to MiWind Air Curtains instead of staying as a bare lookup table. Standard, heated, industrial, ceiling-mounted, and cold-storage air curtain families only make sense after the doorway duty is known.

Heat, Voltage, Controls

Heated and unheated units serve different project expectations. Heating preference affects electrical planning, installation clearance, and current model documents; it should be discussed before a project moves into model selection.

Door switches, wall controls, remotes, and continuous operation also change the selection. For a distributor or contractor, these details are not decorative form fields; they are the difference between a useful equipment request and a follow-up email asking for missing basics.

Installation Notes

A doorway selection becomes useful when the installer can see where the unit will sit. Note whether the air curtain mounts on a wall, above a recessed door, near a ceiling obstruction, or near a sprinkler, sign, light, conduit, or door closer. These details may change bracket choice, cabinet clearance, service access, and electrical routing.

For cold-room and kitchen-adjacent openings, include temperature split, moisture, odor, and makeup-air notes with the doorway dimensions. Those conditions shape the product discussion more than a simple width class.

Application Differences

A front entrance usually needs a cleaner comfort and traffic discussion. A delivery opening needs cycle rate, exposure, and abuse tolerance. A cold-room door needs temperature separation, frost or condensation notes, and current model data. A kitchen-adjacent doorway may need coordination with exhaust and makeup-air conditions.

The same nominal width can lead to different MiWind Air Curtain families because the doorway is doing different work. Treat the chart as the first sorting step, then use the calculator or product page to preserve the field facts.

Keep the document request concise

A useful air curtain request does not need a long narrative. Send the door width, clear height, mounting height, exposure, heat preference, voltage, control expectation, header photos, and application type.

Those details give the distributor enough information to route the doorway toward a standard, heated, industrial, ceiling, or cold-storage option without turning the first conversation into a final model promise.

Doorway sizing check

The short check below establishes a doorway width class and flags unusually tall mounting. Use it as an air curtain size chart by door width and mounting height before the full air curtain sizing calculator, teaching selection logic without replacing equipment review.

Chart Limits

The most common error is selecting by door width alone. The second is assuming the same cabinet length fits a retail doorway and a cold-room doorway. The third is treating an air curtain chart as a final model selector before voltage, heat, mounting, airflow, and model documents have been checked.

Use the table at the end as a doorway reading aid. It is not a certification statement, a code approval, or a final installed-performance claim.
