Awoco 36 On 2-Speed Air Curtain
This Awoco model emphasizes interior/exterior air isolation without functioning as an air conditioner. It uses a high-velocity stream to block up to 90% of incoming air, dust, and smoke, helping to maintain indoor climate. It features a US patented magnetic switch circuit (Patent No. US10584889B2) that automatically powers the unit when a door is opened and turns it off when closed. The unit offers two speeds—high and low—with measured airflow of 1177 CFM at high (58 dB) and 942 CFM at low (56 dB). It operates at 120V, 60 Hz, and 300W, focusing on efficiency and durability with a single motor and ABS fan wheels. The magnetic switch is optional, giving installation flexibility for doors with or without a switch. Suitable for commercial entryways needing a robust, continuous air barrier.
Awoco 24″ Heated Air Curtain For Drive-Thru
This heated air curtain is designed for restaurant drive-thru windows rather than doorways. It delivers warmth to personnel as they operate windows more frequently, while the airflow is not intended to reach floor level. The unit provides 240V, 3000W (two heating levels at 1500W and 3000W) and 160 CFM of airflow. It requires a compatible 240V outlet with a 20A circuit and does not include a plug or power cord. Notable features include dual heating levels to balance warmth with energy use and a lower but steady airflow profile suitable for drive-thru environments that prioritize comfort during window service. Noise is kept relatively low at 48 dB for practical use around customer-facing operations.
Mars Air Systems LPV272-1EBF-OB LoPro 72″
The LoPro LPV272-1EBF-OB offers a substantial 72-inch heated air curtain with a ⅙ HP direct-drive motor. It includes a control panel, remote thermostat, and variable-speed control for precise temperature and airflow management. The combination of heating capability and flexible speed settings makes it suitable for larger entrances where a strong, adjustable thermal barrier is needed. The configuration is aimed at professional or commercial installations seeking consistent performance with simplified control interfaces.
Mars Air Systems LPV248-1ECD-OB LoPro 48″
This 48-inch LoPro model emphasizes a compact, lowest-profile design with a heated option. It features a HP direct-drive motor, variable-speed control, and aims to deliver efficient performance in smaller entrances or spaces where ceiling height is a constraint. The 60 Hz, 230V single-phase configuration provides robust heat output while maintaining a manageable footprint. Its emphasis on a streamlined profile makes it suitable for storefronts, small offices, or restaurant interiors where less obtrusive equipment is desired without sacrificing barrier effectiveness.
Awoco 72″ Elegant 2-Speed Air Curtain
The 72-inch Awoco unit is designed for large entrances, offering two speeds with a high-performance airflow of up to 1878 CFM at high and 1482 CFM at low, with noise levels of 55 dB and 52 dB respectively. Operating at 110–120V, it uses 600W and is designed to minimize energy use while maximizing protective airflow. A magnetic door switch is included to automate operation for open doors, aligning with modern energy-saving practices. The unit’s engineering emphasizes a balance between powerful wind force and controlled noise, making it a practical option for retail storefronts, large office lobbies, or warehouse entryways that require a strong, quiet barrier to drafts and pollen.
Mars Air Systems LPV248-1EEI-OB LoPro 48″ 3-Phase
This model mirrors the LPV248-1ECD-OB with 208V/3 phase operation and a heated, 13 kW capacity, facilitating heavy-duty commercial use. It includes variable-speed control and a compact profile for easier integration into larger commercial settings where strong heat and airflow are essential to maintaining comfortable interior conditions and reducing energy losses through entrances. The three-phase configuration supports higher power delivery for demanding environments like large retail spaces or multi-door facilities requiring consistent barrier performance.
DuraSteel 40″ Wall Mounted Air Curtain
DuraSteel offers a 40-inch wall-mounted air curtain designed for doors and storefront entrances. It emphasizes a UL-certified motor, providing thousands of hours of operation with a powerful yet low-noise airflow barrier.

The emphasis is on safe operation, energy efficiency, and versatility across different configurations for small to medium entrances requiring supplemental heat without overpowering airflow.
Buying Guide
Key purchase considerations when selecting an electric heated air curtain:
- Entrances and dimensions: Measure door width and clearance to select a unit with appropriate length and airflow coverage. Larger openings may benefit from wider or multi-speed models.
- Heating needs vs. cooling concerns: Heated curtains should complement, not replace, building heating strategies. Ensure the unit’s heating level aligns with interior climate goals and energy budgets.
- Voltage and power requirements: Check available electrical service (120V vs. 208V/240V) and circuit capacity. Higher wattage models require robust power supply and proper wiring.
- Control features: Look for built-in thermostats, remote controls, and auto-switch technologies (e.g., door-switch-based activation) to optimize performance and energy use.
- Noise and airflow: Consider target noise levels and CFM ratings. Quieter units are preferable in customer-facing spaces, while higher CFM suits busy entryways.
- Durability and warranties: Prioritize UL certification, material quality, and motor longevity for commercial applications. Confirm warranty terms for long-term maintenance.
- Installation: Some units are wall-mounted, others fit over doors or drive-thru windows. Ensure compatibility with existing door frames and electrical outlets, and assess whether professional installation is needed.
- Maintenance considerations: Look for easy-access components, protective housings, and materials that resist dust, moisture, and insects to minimize downtime.
- Energy efficiency: Compare heat output relative to power consumption. Units offering adjustable heating in tandem with variable-speed fans typically deliver better energy efficiency.
- Environmental impact: Consider whether the unit reduces drafts and air leakage effectively to lower overall heating costs and improve comfort.
Across different settings such as storefronts, restaurants, and office buildings, heated air curtains provide a protective barrier that improves comfort and helps control environmental exchange. When evaluating options, balance size, heating capacity, energy use, and noise to select the best fit for your space and traffic patterns.
