Product Overview
The AOSUNFAN Air Curtain (Model AC-36H) is a heavy-duty heated airflow barrier designed for high-traffic commercial entrances and industrial doorways. With a 36-inch (91 cm) coverage width and 180W PTC heating element, it generates a 6-12 m/s high-speed thermal air stream to block cold drafts while maintaining indoor temperatures (ASHRAE 62.1 compliant). Featuring an IP54-rated galvanized steel housing and 110V/220V dual-voltage motor, this Air Curtain delivers 1,500-3,200 m³/h airflow with ≤52 dB(A) noise levels (ISO 3744 tested). Includes adjustable mounting brackets for 2.2-3.0m installation heights and smart temperature control via infrared remote.

FAQ
Q1: How does this heated Air Curtain differ from standard door heaters?
Unlike localized radiant heaters, our Air Curtain creates a continuous thermal barrier across the entire doorway, improving energy efficiency by 40% while eliminating drafts.
Q2: Minimum ceiling height requirement?
Optimal performance between 2.4-3.0m; includes 15° adjustable nozzles for angled installations.
Q3: Cleaning frequency for kitchen environments?
Degrease monthly with alkaline cleaner (pH 9-11); replace carbon pre-filters every 3 months.
Q4: Smart temperature control options?
Supports WiFi thermostat integration (2.4GHz) with programmable schedules via iOS/Android apps.
