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.

📍 Who Should Buy This?
- 🏭 Factory & plant gates — personnel and small-vehicle entrances where the door stays open during shift changes and material movement.
- 🚚 Warehouse loading bays — forklift and dock-door openings where dust, fumes and pest ingress need to be sealed off without slowing operations.
- ❄️ Cold rooms & chillers — reduces condensation and energy loss at chiller entrances.
- 🍳 Commercial kitchens & food processing — keep flies, dust and odour out of prep areas while staff move freely between hot and cold zones.
- 🏥 Hospital service entrances — ambulance bays, mortuary access, supply doors where pest and contaminant ingress must be controlled 24×7.
- 🏫 Auditoriums & banquet halls — large-format public entrances with heavy footfall, where long running hours matter more than anything else.
🛠️ Installation Notes
- Mount horizontally above the door frame, height 2.4–3.2 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 (3,500 CFM), then low mode for off-peak hours.
- Clean filter grille every 30 days (dust load varies by location).

📖 Product Overview & Buyer Guide
The 7 Feet Metal Body Advanced air curtain is engineered for the toughest Indian commercial and light-industrial conditions. With a 440W industrial copper motor stack pushing 3,500 CFM through a powder-coated steel housing, this unit handles factory gates, warehouse loading bays, cold-room entrances, large kitchen pass-throughs and food-processing plants where entry-grade units wear out. Industrial premium-grade copper motors, a High/Low 2-speed switch, a free automatic door sensor, thermal cut-off and a 5-year warranty make this the unit Chronovex specifies when downtime is not an option.
🏅 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 Advanced 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 specify Metal Body Advanced over Premium or Standard?
Premium and Advanced give the same airflow and wattage and both have a High/Low switch. The difference is the grade of the motor, blower and housing: Premium uses higher-grade copper-wound motors and blowers for extended daily operation (8–10 year service life, 3-year warranty), while Advanced uses industrial premium-grade motors, blowers and housing for 24×7 continuous duty (15–20 year service life) at factory gates, loading bays, cold rooms and busy commercial kitchens (5-year warranty, automatic door sensor included free). If the door stays open through long shifts or the unit runs round the clock, Advanced is the right specification.
