- 💨 High-velocity jet — jet reach up to 3.3 m at 16 m/s outlet velocity — seals doors against strong wind, monsoon draft and pressure differentials.
- ❄️ Cold-chain seal — stops cold air from escaping cold-storage / blast-freezer doors; cuts compressor cycling by 30–40%.
- 🦟 Insect, fume & dust block — 1,500 CFM continuous barrier stops flies, kitchen fumes, road dust and PM2.5 from drifting through the open doorway.
- 🛡️ 3-year extended warranty — industrial-grade build comes with extended 3-year warranty (vs 1-year on Standard / Premium).

📍 Who Should Buy This?
- Shopping malls & multiplexes — main entry doors up to 0.9 m wide
- Factory & warehouse gates — production-floor entries with constant forklift traffic
- Cold storage & blast-freezer doors — needs heater-off cold-chain seal
- Food processing & dairy plants — FSSAI-compliant fly/pest barrier at production entries
- QSR kitchens & cloud kitchens — high-fume / high-heat back-door entries
- Hospitals & pharma plants — positive-pressure ward and clean-room entries
🛠️ Installation Notes
- Mount horizontally above the door frame, height 2.2–3.2 m (lower = stronger barrier).
- Air jet should point slightly outward (5–10°) to deflect incoming flies/dust.
- Plug into a dedicated 5 A / 220 V outlet — no rewiring needed.
- Test high mode first (1,500 CFM), then low mode for off-peak hours.
- Clean filter grille every 30 days (dust load varies by location).
❓ Quick FAQ
Q. Does the heater come pre-installed in the Advanced 3 Feet?
No — the heater port is built in, the PTC heater module ships as an optional accessory (3 kW or 6 kW). For unheated use (mall entries, factory gates) the unit works as a standard high-velocity air curtain.
Q. How is Advanced different from Standard 3 Feet?
Advanced uses a reinforced 1.0 mm steel body (vs 0.7 mm Standard), heavy-duty industrial motors rated for 18-hour duty, higher outlet velocity (16 m/s vs ~12 m/s Standard), heater-port readiness, and a 3-year warranty (vs 1-year). Standard is built for retail; Advanced is built for industry.
Q. Can I run this 24/7 in a factory?
Yes. The Advanced series is rated for 18-hour continuous operation per day. For true 24/7 use across multiple shifts, we recommend dual units mounted side-by-side on rotational duty cycles — our application engineer can spec this on a call.

📖 Product Overview & Buyer Guide
The Chronovex 3 Feet Advanced Aluminium Air Curtain is the industrial-grade variant in our 3 feet range — built for shopping malls, factory gates, cold-storage doors, food-processing entries and other high-traffic commercial doorways across India. Same 1,500 CFM peak airflow as the Standard and Premium, but with a reinforced 1.0 mm steel body, heavy-duty 2-motor setup, higher 16 m/s outlet velocity, optional 3 kW / 6 kW PTC heater module for winter use, and a 3-year extended warranty. Ideal for buyers in Delhi NCR, Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata, Ahmedabad, Surat, Indore, Jaipur and Lucknow who need a door curtain that runs 18 hours a day in a tough environment.
🏅 Manufacturing & Quality
Chronovex Industries Pvt. Ltd. manufactures every air curtain at our ISO 9001:2015 certified facility in Noida, Uttar Pradesh. Each 3ft Aluminium Advanced unit passes 12 QC checkpoints — motor balancing, blower alignment, voltage stability (200–240 V tolerance), thermal cut-off testing, noise level (≤65 dB at 1 m), and a full 30-minute run-test before packaging.
⚙️ Why buyers pick the Advanced 3 Feet over Standard / Premium
Three reasons. First, the heater port — plug in the optional 3 kW or 6 kW PTC module and the unit becomes a warm-air curtain for winter use, critical for cold-storage rooms (keeps frost off the doorway) and factory entries in north India where January temperatures drop below 5 °C. Second, the reinforced 1.0 mm steel body and heavy-duty motors rated for 18-hour continuous operation — retail-grade Standard / Premium units burn out under industrial duty cycles. Third, the 3-year warranty — our procurement-team conversations consistently show that factory and mall buyers won’t buy a 1-year-warranty curtain for a 24/7 doorway. If your application is industrial, food-processing, cold-chain or mall-traffic, Advanced is the only Chronovex line built for it.
