Product Overview
The AOSUNFAN Air Curtain (Model AC-HC36) is a commercial-grade heated airflow barrier designed for high-traffic entrances in cold climates. Featuring a 36-inch (91 cm) width and 1200 CFM dual-speed airflow, this Air Curtain combines 3kW ceramic PTC heating with a vertical air barrier to prevent heat loss and outdoor contaminants (ASHRAE 90.1 compliant). Constructed with stainless steel housing (IP55-rated) and aerodynamic aluminum blades, it operates at ≤60 dB(A) (ISO 3744 tested) with 220V/240V compatibility. Integrated with smart thermostats (-30°C to 40°C range) and humidity sensors (20-95% RH) for adaptive climate control in warehouses, supermarkets, and industrial facilities.
Product Features
Dual-Speed Heating
Low (800 CFM / 1.5kW) & High (1200 CFM / 3kW) modes with ±2°C temperature stability (EN 60335-2-30 certified).
Energy-Efficient Heating
Ceramic PTC elements achieve 98% thermal efficiency (ISO 15042 tested), cutting heating costs by 35% vs. conventional units.
