📖 Product Overview & Buyer Guide
The Chronovex 7 Feet Aluminium Standard Air Curtain is purpose-built for the widest single-door entries that single-phase power can handle (up to 2.1 m / 7 ft) — large mall stores, warehouse offices, food processing entries, hospital wards. With a 440 W 4-motor + 7-blower setup delivering 3,500 CFM peak airflow, this unit produces one continuous high-volume air sheet at ~₹28/day running cost on high mode.
🏅 Manufacturing & Quality
Chronovex Industries Pvt. Ltd. manufactures every air curtain at our ISO 9001:2015 certified facility in Noida, Uttar Pradesh. Each 7 ft Aluminium Standard unit passes 12 QC checkpoints — motor balancing, blower alignment, voltage stability (200–240 V tolerance), thermal cut-off testing, noise level (≤68 dB at 1 m), and a full 30-minute run-test before packaging.
⚙️ Why 7 ft Aluminium vs 6 ft Metal
Both deliver 3,500 CFM — the choice is voltage and environment. 7 ft Aluminium runs on a standard 220 V single-phase outlet (no electrical upgrade needed) and is best for indoor air-conditioned spaces. 6 ft Metal needs 3-phase 415 V wiring (industrial / commercial buildings) but has a thicker metal body for outdoor, dusty, or coastal environments. If your building has a regular plug socket, pick 7 ft Aluminium.
