A busy entryway shouldn’t be a battle between indoor comfort and outdoor weather. Air curtain doors create a wall of moving air across an open doorway, blocking flying insects, dust, summer humidity, and winter drafts without sealing the door shut. The right unit depends on door width, mounting height, and whether the space is a quiet café or a bustling warehouse dock.
An Overview Of The Picks
Awoco 36″ Super Power 2-Speed 1200CFM Commercial Air Curtain
Awoco 42″ Super Power 2-Speed 1350CFM Commercial Air Curtain
DuraSteel 40″ Wall Mounted Commercial Air Curtain
DuraSteel 36″ Wall Mounted Commercial Air Curtain

A Deeper Look At The Lineup
Awoco’s 36-inch Super Power is the workhorse of the lineup, moving 1200 CFM (cubic feet of air per minute) across a standard three-foot doorway. The two-speed motor lets you dial down output for slow-traffic hours and crank it up when the lunch rush hits. It runs unheated, so there is no heating element to maintain, and it pairs with a magnetic door switch that toggles the unit on only when the door opens.
For shop owners tired of flies drifting in with every customer, this is a practical upgrade over a basic pedestal fan. The UL certification (an independent safety standard for electrical products) on the motor is the kind of detail insurance inspectors tend to look for in commercial settings.
The Helpful Details
- 1200 CFM output handles a standard 36-inch door without leaving gaps at the edges
- Two-speed switch lets you tune airflow to traffic volume, saving energy during slow periods
- Magnetic door switch automates operation, so the unit only runs when needed
- UL-certified motor meets common commercial safety requirements
Things To Consider
- Unheated design means it won’t warm incoming air in winter
- Mounting above a doorway requires a drill and basic wiring comfort
Key Specs
Who It Suits Best
Café and retail owners with a steady stream of foot traffic who want reliable insect and draft control without a heated unit.
Consider Something Else When
The Awoco 42″ Super Power 2-Speed 1350CFM Air Curtain suits wider openings, like loading docks or double doors, where this 36-inch model would leave uncovered edges.
Step up to the Awoco 42-inch and the extra six inches of width become the headline feature. At 1350 CFM, this model pushes more air than the 36-inch version, which matters when the doorway is taller or wider than standard. It still uses the same two-speed motor and magnetic switch setup, so the controls feel familiar.
Garage entrances, warehouse doors, and busy back-of-house passages are where this unit earns its keep. Compared to the first pick, it trades a smaller footprint for broader coverage, and that swap makes sense in spaces where a 36-inch curtain would visibly leave gaps at the edges.
Useful Touches
- 1350 CFM handles taller and wider openings without losing barrier strength
- 42-inch width covers double-door and commercial loading entries
- Same magnetic switch system as the smaller Awoco model, simplifying installation
Points To Note
- Larger housing may require extra wall clearance during installation
- Higher airflow also means more noticeable sound at top speed
Made For
Workshop and warehouse managers running wide openings where a standard 36-inch curtain would be undersized.
Look Elsewhere When
The Awoco 36″ Elegant 2-Speed 900 CFM Air Curtain is a smarter match for small shops that don’t need the extra coverage this 42-inch unit provides.
The DuraSteel 40-inch splits the difference between the two Awoco widths, and that middle-ground sizing suits a lot of real-world doorways. It ships as part of the “Fly Fans” lineup, which is DuraSteel’s way of signaling insect-blocking priority. The MS (magnetic switch) setup mirrors what Awoco uses, so the on-and-off automation feels familiar.
Compared to the Awoco 42-inch, this 40-inch model gives up a couple of inches of coverage but compensates with a white housing that blends more easily into bright retail and restaurant interiors. It is a flexible pick for spaces that don’t quite need the largest size on this list.
The Practical Payoff
- 40-inch width fits openings that are wider than standard but not full double-door size
- White housing fits cleaner into bright retail and restaurant aesthetics
- Magnetic door switch integration avoids manual on-and-off routines
Worth Noting
- Airflow output is not specified in the source, making cross-model comparison harder
- Periodic grille cleaning is commonly needed to keep output steady in dusty kitchens

A Better Fit Elsewhere
The DuraSteel 36″ Wall Mounted Air Curtain suits narrower standard doorways where this 40-inch version would overlap the wall.
The 36-inch DuraSteel is the smaller sibling to the 40-inch model, and it targets the most common commercial doorway size head-on. The motor is built for long stretches of continuous operation, which is the right kind of durability for a café or shop that opens at seven in the morning and closes at nine at night.
Where the Awoco 36-inch Super Power leans on raw airflow, this DuraSteel emphasizes sustained run time. The trade-off is that you may find the noise floor slightly higher during marathon shifts, depending on the mounting height and door acoustics. For most daily-use scenarios, the difference is minor.
What Works In Its Favor
- 36-inch width is the most common commercial door size, making fit straightforward
- Motor rated for extended continuous run times
- Wall-mounted design keeps walkways and floor space clear
Small Caveats
- Airflow rating is not detailed in the source data
- Continuous-duty use may require occasional bearing inspection over the years
Whose Shelf It Belongs On
Shop and café owners running long daily hours who need a unit that can handle continuous duty without overheating concerns.
Swap It Out When
The Awoco 36″ Elegant 2-Speed 900 CFM Air Curtain is a better match for light-use doors where this DuraSteel’s continuous-duty design would be overkill.
The “Elegant” in the name is a clue: this is Awoco’s residential-leaning design, with a lower 900 CFM output aimed at lighter-duty entryways. It uses the same two-speed motor and magnetic door switch as the Super Power line, so the controls stay consistent across the brand.
It is a sensible match for a home workshop, a small studio, or a back door that sees a handful of openings an hour rather than dozens. Compared to the Awoco 36-inch Super Power, the trade-off is clear: you give up a third of the airflow in exchange for a more modest unit that suits spaces where full commercial power is unnecessary.
What Pays Off
- 900 CFM is enough for low- to medium-traffic doorways without overspending on capacity
- Same magnetic switch setup as other Awoco models, simplifying the install
- Compact motor housing fits tighter ceiling clearances
Honest Caveats
- Lower airflow may not hold up against strong crosswinds in exposed doorways
- Unheated design does nothing for winter chill at the threshold
- Grille dust buildup is commonly reported on similar lower-output units, so periodic wiping helps

Reach For A Different Pick When
The Awoco 36″ Super Power 1200CFM Air Curtain is a stronger fit for busier commercial doorways where 900 CFM would feel underpowered.
Choosing the Right Air Curtain Door for Your Space
Air curtain doors are not one-size-fits-all. Door width is the first filter, since a curtain that doesn’t span the full opening leaves gaps where insects and drafts slip through. Measure the doorway at its widest point, including any trim, and match the unit’s width to that number. A 36-inch model suits most standard entries, while 40- and 42-inch units cover wider commercial and warehouse doors.
Airflow, measured in CFM (cubic feet per minute), is the second key attribute. Higher CFM means a stronger air barrier, but it also means more noise and energy use. Light-traffic doorways do fine around 900 CFM, while busy entries benefit from 1200 to 1350 CFM.
Mounting height and door-switch automation are practical details that matter during installation. Wall-mounted units with magnetic door switches turn on only when the door opens, which saves energy and reduces wear. Units rated for continuous-duty run times are worth prioritizing in commercial settings that open early and close late. Finally, consider housing color and noise tolerance: white units blend into retail interiors, while louder high-speed settings may be a poor match for quiet offices or front-of-house spaces.
What To Know Before You Commit
Common Shopping Slip Ups
The most frequent mistake is matching airflow to door size alone. A unit with plenty of CFM still underperforms if the mounting height is too high or too low, since the air stream needs to reach the floor cleanly. Measure ceiling clearance before picking a model. Another pitfall is overlooking the magnetic door switch, which sounds optional but actually drives most of the energy savings. Without it, the curtain runs constantly and the motor wears out faster.
Where The Extra Money Goes
Higher-tier models earn their keep with stronger motors, wider housings, and longer continuous-duty ratings. The jump from a 900 CFM unit to a 1350 CFM unit is not just about more air, but about a motor built to push that air for thousands of hours without thermal issues. In busy commercial settings, that durability difference shows up as fewer service interruptions and a longer service life.
Frequently Asked Questions
Do air curtain doors actually keep bugs out? Yes, when properly sized and mounted. The high-speed air stream disrupts the flight path of flying insects, making it hard for them to enter. Effectiveness drops if the curtain is too narrow for the doorway or mounted too high.
Can an air curtain door replace a closed door? No. An air curtain is a barrier of moving air, not a physical seal. It works best when the door is open, reducing drafts, insect entry, and temperature exchange between inside and outside.
How loud are air curtain doors? Most commercial units produce a steady fan hum, similar to a box fan on medium. Higher CFM settings are noticeably louder, which matters in quiet front-of-house spaces like offices or cafés.
Do I need a heated air curtain? Only if you want the unit to warm incoming air in winter. Unheated models handle insect and draft control year-round but do not add heat to the airstream. Heated versions cost more and use more electricity.
How is an air curtain door installed? Most wall-mounted units attach above the doorway with included brackets and require a standard 120V outlet nearby. The magnetic door switch mounts to the door frame and pairs with the unit to automate on-and-off operation.
