Awoco 24″ 240V Heated Air Curtain for Drive-Thru Windows
Notes: This model is designed specifically for restaurant drive-thru windows, not doors. It offers two heating levels (1500W and 3000W) and a primary airflow of 160 CFM. It requires 240V and a compatible 20A circuit. The unit prioritizes keeping warm air inside while reducing cold-air infiltration, helping to improve staff comfort and maintain interior temperatures. Best for: drive-thru operations where doors open repeatedly and space is tight. Limitation: airflow may not reach the floor, which can limit full-room warming in larger spaces.
Who it’s best for
- Restaurants with frequent drive-thru window use that need quick warmth near the opening.
- Settings where a 240V supply and dedicated circuit are readily available.
Key features at a glance
- Two heating levels: 1500W and 3000W
- 160 CFM airflow for focused warmth
- Low noise design at 48 dB
- No plug included; requires compatible cord and plug
Fanspex 36″ Wall Mounted Air Curtain
The Fanspex model is an unheated air curtain designed to create a strong air barrier at doorways. It is best for blocking outdoor dust, insects, and drafts in high-traffic entrances where temperature control is not required. It features two speeds (high and low) and uses a low-wConsumption 120W motor for energy savings, with a noise profile around 55–58 dB, making it suitable for busy areas such as kitchens and wait lines. Limitation: since it does not heat air, it does not contribute to warming indoor spaces during cold weather.
Who it’s best for
- Restaurants wanting to reduce heat loss without adding heating load near doors.
- Establishments seeking a high-speed, low-noise door barrier at standard entrances.
Why choose this
- Low energy consumption compared with heated models
- Two speeds optimize airflow based on foot traffic
Wostore 36″ Air Curtain for Doorways
This model is explicitly described as an air curtain (not heated or cooled) designed to block heat exchange and keep interiors clean from dust and insects. It uses a 110V-120V input and provides two speeds with a modest 1357 CFM on high. It is best for environments where a physical barrier is not possible or desired, but temperature control is not needed. Limitation: it does not actively heat or cool the air.
Who it’s best for
- Small to mid-sized restaurants that want a non-heat barrier to reduce energy losses and pests.
- Spaces where a magnetic switch and remote features simplify operation.
Best-use note
- Not suitable where heated air is required to maintain indoor comfort.
HXCOCKCROW 36 Inch Non-Heat Air Curtain
The HXCOCKCROW 36″ air curtain is designed for indoor and outdoor separation without heating. It emphasizes strong airflow and low noise, suitable for entrances where a barrier is needed to stop insects and reduce outdoor air intrusion. It includes a magnetic door switch for simple installation. Limitation: again, it does not warm air, which may be a drawback in cooler climates or seasons.
Who it’s best for
- Restaurants desiring a robust air barrier to reduce drafts and pests.
- Businesses needing a simple, efficient door fan with a magnetic switch.
Why this matters
- High CFM and durable build help protect indoor climate without adding heater load.
Awoco 36” Black 2-Speed Air Curtain (Unheated)
This Awoco model is an unheated air curtain designed to isolate interior from exterior air. It uses a magnetic switch control and offers two speeds, with airflow around 1177 CFM at high and 942 CFM at low. It runs on 120V, consuming relatively low power. Best for environments where heat addition is not required but you still want an air barrier to keep dust and smoke at bay. Limitation: does not contribute to heating interior spaces.
Who it’s best for
- Establishments needing a high-speed air curtain with magnetic switch control.
- Spaces where energy efficiency and compact installation are priorities.
What to expect
- Strong barrier performance with moderate energy use.
- Reliable magnetic switch-based operation for heavy door traffic.
KBZZ 48 Inch Wall-Mounted Air Curtain (Heated optional)
The KBZZ unit is a wall-mounted air curtain with magnetic switch and multiple speeds. It is described as a commercial model with three speed choices and strong air volume (CFM). The features emphasize isolation of interior from exterior air and energy-conscious operation. This model is unheated, so it’s best when temperature control is not a requirement but airflow and barrier performance are. Limitation: lacks heating function for cold-weather comfort.
Who it’s best for
- Restaurants needing a large doorway barrier to minimize drafts and pests.
- Spaces that require easy installation and a durable magnetic switch control.
S-LP-108-2-VS-EH 108″ Commercial Heated Air Curtain
This large, low-profile heated air curtain provides a substantial airflow up to 3640 CFM. It includes an electric heater and is designed for tall, wide doorways common in fast-paced restaurant settings. The heater helps maintain comfortable conditions near entryways while reducing the influence of outdoor air. Limitation: installation requires precision given its size; ensure structural clearance and electrical availability for 208V/3-Phase operation as applicable.
Who it’s best for
- Large restaurants or stadium-style cafeterias with wide openings and heavy door traffic.
- Facilities needing strong, consistent heating near entrances to improve comfort and energy efficiency.
Why this selection
- Very high CFM with integrated heater for cold-weather warmth near doorways.
- Suitable for big entryways where smaller units struggle to deliver warmth.
Buying Guide: Key Considerations for Heated Air Curtains in Restaurants
Do you need heated air or just a barrier?
Heated air curtains actively warm air near entrances to improve comfort and reduce cold air infiltration. If your primary goal is only to block dust, insects, or drafts without heating, unheated models can save energy and reduce operating costs.
What doorway size and traffic matter?
Choose a unit with airflow measured in CFM appropriate to door width and typical foot traffic. Large openings or high-traffic areas benefit from higher CFM and multi-speed options, while smaller doors may suffice with mid-range airflow.
Electrical requirements and installation
Heated models often require 208V–240V power and dedicated circuits. Confirm outlet availability, plug type, and mounting space. Magnetic switches simplify installation and reduce mechanical wear compared with traditional plunger switches.
Noise and maintenance considerations
Most industrial air curtains operate quietly enough for restaurant environments, but noise levels vary. Look for units under 60 dB for comfort near seating and service areas. Regular cleaning of fans and vents helps sustain performance over time.
Energy efficiency and long-term costs
Heated systems can lower energy costs by reducing the need to reheat entire spaces. Compare heater wattage, motor efficiency, and overall airflow to estimate long-term operating costs. For occasional use, unheated curtains can be a practical and energy-efficient choice.
Installation location tips
- Install at a height and width that aligns with doorway dimensions for maximal barrier effectiveness.
- Ensure the unit does not interfere with door operation or occupant movement.
- Consider wind and draft directions from external doors to optimize performance.
Frequently asked questions
- What is the difference between heated and unheated air curtains? Heated curtains include an integrated heater to warm air near the opening, while unheated curtains provide a barrier of moving air without heating.
- Can heated air curtains save energy in a restaurant? Yes, by reducing heat loss and moderating indoor temperatures near entrances, they can lower the heating load in cold weather.
- Will these units reduce pests entering a restaurant? Air curtains create a physical-like barrier of moving air that helps limit insect entry when doors are open.
- What should I check before buying? Door width, mounting space, electrical supply, noise level, and whether heating is needed for your climate and season.
- Are magnetic switches important? Magnetic switches simplify installation and improve durability by avoiding direct contact parts that wear with door slams.
- Do heated air curtains work for drive-thru windows? Yes, heated models designed for drive-thru use quickly deliver warmth to staff near the window and help maintain interior comfort.
