Standard vs Premium vs Advanced — what actually differs
For a given size, all three deliver the same airflow, wattage and CFM. The difference is not the specification — it is the grade of the components behind it. A 100% copper motor can be sourced at very different price points; the rating stays the same while life, durability and support do not. That grade is what separates these three series, and the onsite warranty reflects it.
| Standard | Premium | Advanced | |
|---|---|---|---|
| Best suited for | Shops, offices, showrooms | Hotels, malls, hospitals | Factories, warehouses, cold storage |
| Duty cycle | Regular daily use | Extended daily operation | 24×7 continuous |
| Motor grade | Entry-grade 100% copper | Higher-grade 100% copper | Industrial premium-grade |
| Expected service life | 3–5 years | 8–10 years | 15–20 years |
| Onsite warranty | 1 year | 3 years | 5 years |
| Airflow / wattage / CFM | Same | Same | Same |
Body gauge and bearing type are common across the range; the difference lies in component quality and sourcing.

❓ Quick FAQ
Q. Will this fit my 2.1 m door?
Yes — designed for doors up to 2.1 m wide. For wider, step up one size in the Metal Premium ladder, or look at Metal Advanced.
Q. How loud is it really?
Up to 68 dB at 1 m on High speed; the Low speed setting runs quieter.
Q. Steel body vs aluminium — which lasts longer?
Steel powder-coat is more dent-resistant for high-traffic. Aluminium is lighter and has a brushed look for upscale showrooms. Mall doors, factory canteens, hospital lobbies: pick steel.
Q. Is the warranty different?
3 years on motor + electricals, same as aluminium. Spares stocked in Noida for same-day pan-India dispatch.

📖 Product Overview & Buyer Guide
The Chronovex 7 Feet Metal Body Premium Air Curtain is built for B2B buyers who want a heavier, more durable shell than the aluminium series — without going up to industrial stainless steel. The CRCA powder-coat white body resists day-to-day knocks, the 4-motor copper-wound setup keeps noise under 68 dB at 1 m, and the High/Low switch lets you save power when traffic is light. Ideal for buyers in Delhi NCR, Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata and Ahmedabad who want a curtain that takes daily use — mall entrances, showroom doors, clinic receptions, restaurant fronts — and still looks clean five years in.
🏅 Manufacturing & Quality
Chronovex Industries Pvt. Ltd. manufactures every air curtain at our ISO 9001:2015 certified facility in Noida, Uttar Pradesh. Each 7ft Metal Body Premium Series 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 buyers pick the Metal Body Premium 7 Feet over Aluminium
Three reasons keep showing up in our B2B procurement calls. First, the powder-coat steel body survives forklift bumps, cleaning trolleys, and pallet corners that brushed aluminium would scratch. Second, the 4-motor copper-wound layout is service-friendly: spares are interchangeable across the steel-series ladder so your facility team stocks one set of blower wheels. Third, the white powder-coat finish stays neutral against any wall colour — unlike brushed aluminium which clashes with warm interiors. For mall doors, hospital lobbies, factory canteens — 200+ open-close cycles per day — Metal Body Premium pays for itself in not needing a re-paint or replacement at year three.
