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.
Is the 4 ft Aluminium Premium air curtain right for your door?
This model covers doors wider than 1 m (3.3 ft) and up to 4 ft wide. The air curtain should be at least as long as the door opening, so the air stream covers the full width. It is typically used on regular shop and showroom doors, restaurant entrances, banks, ATMs and office receptions. If your door is wider than 4 ft, choose the 5 ft model. Doors wider than 7 ft use two or more units side by side; the door size price finder works out the exact combination.
The aluminium body is light and a good fit for shops, offices and showrooms. Price for this model: ₹23,639, GST and installation included. The final quote is confirmed on WhatsApp after we see a photo of your door.

At a glance — Air Curtain 4 Feet, Aluminium Body, Premium Series
The Chronovex 4 Feet Aluminium Body Premium Series air curtain is engineered for everyday commercial use: a single 1220 mm unit installed above a doorway pushes a continuous 14 m/s air sheet downward, blocking the doorway against AC loss, flying insects, dust, and PM2.5 ingress while shoppers and staff walk through freely. Extruded aluminium housing, copper-winding motors and a dual-speed switch make it the workhorse choice for retail floors, salons, clinics, branch offices and quick-service kitchens across India.

Key features
- 2-motor / 4-blower architecture — redundant airflow paths keep the air sheet uniform even if one blower module needs service; common spare parts are stocked at the Noida plant.
- Copper-winding motors (not aluminium) — lower coil resistance, less heating, longer service life under daily 8–12 hour duty cycles.
- Dual-speed switch — run on Low for AC retention in monsoon & off-peak hours, switch to High for peak footfall and lunch-rush at QSR doors.
- Extruded aluminium body with powder-coat finish — resists humidity, salt-air corrosion and minor impact during cleaning.
- Pest, fly & dust barrier — the down-jet velocity at 14 m/s exceeds the take-off threshold of most flying insects, complementing your insect-killer line.
- Energy retention — keeps conditioned air inside, reducing AC compressor cycles by an observed 8–18% on shop-front doorways with the unit fitted (varies by door size & AC tonnage).
- Premium-Series components — higher-grade copper motors for extended daily operation in hotel lobbies, banks and showrooms; for 24×7 industrial duty see our 4 ft Advanced Series.

Installation overview
The 4 ft Premium Series mounts on the lintel directly above the door opening, with the discharge slot facing downward. Typical installation:
- Mount height: install so the discharge nozzle sits 75–85 mm above the door head — not flush with the lintel face.
- Electrical: 220 V, 5 A dedicated MCB recommended; cable run from the nearest distribution board, with earth bond to the housing chassis stud.
- Switching: the Hi/Lo selector can be wall-mounted near the door staff station or wired into the existing shop-front lighting circuit.
- Lead time: same-day dispatch from Noida; Delhi NCR same-day delivery, every other pin-code 4–7 days.
- Installation network: Chronovex has a certified installer network across India — mention pin-code on the bulk-quote WhatsApp for an installation-included price.
Frequently asked questions
How long does installation take?
For a single 4 ft unit with existing 220 V supply at the door head, a Chronovex certified installer typically completes mounting, electrical termination, and a 30-minute commissioning test in 2–3 hours. Civil work (new conduit / MCB) adds another 2–4 hours.
What is the operating cost?
At ~240 W full-load on High speed and ₹8/kWh commercial tariff, the unit draws about ₹1.9/hour or roughly ₹630/month for a typical 10 AM–9 PM retail shift. Running on Low speed (~180 W) cuts that to roughly ₹480/month. Net energy saved from reduced AC compressor cycles is usually larger than the curtain's own draw.
Can it be installed outdoors?
The Premium Series is rated for sheltered indoor / semi-outdoor (covered porch) use. For fully exposed outdoor entries facing direct rain, ask for our outdoor-rated build or specify an SS304 grade with a drip-shield modification.
What is the payback period from AC savings?
For a centrally air-conditioned retail store with the door open through the day, observed AC-load reductions of 8–18% typically pay back the curtain's landed cost in 8–16 months. Payback shortens significantly in summer-peak cities (Delhi NCR, Ahmedabad, Hyderabad).
What is the HSN code and GST rate?
HSN 8414 59 10 (air curtains) attracts 18% GST in India. A tax invoice is issued from Chronovex Industries Pvt. Ltd., Noida (GSTIN on request) — eligible for full input credit by registered B2B buyers.
Does it ship with a warranty?
Yes — 3 years manufacturer warranty against manufacturing defect from the date of invoice. Extended AMC (up to 5 years) is available for B2B projects on request. For warranty claims call +91 9997778202 or write to customercare@chronovex.in.

Extended FAQs — 4 ft Aluminium Body Premium Series
Will the 4 ft Aluminium Premium work on a 7 ft door?
Yes, the 4 ft (1220 mm) Premium Series comfortably seals door heights up to 7–8 ft. For a 9–10 ft door, the Advanced 4 ft or 7 ft size is recommended.
Will it block mosquitoes and dust at a restaurant entrance?
Absolutely. The 2,000 CFM discharge force blocks insects, dust, exhaust fumes and AC loss. It is popular everywhere — restaurants, sweet shops, kirana stores, pharmacies.
Does it need single-phase 220V or 3-phase?
240W rated 4 ft Premium — runs directly on single-phase 220V/50Hz. Normal plug or hardwire — both supported.
How long does installation take?
A standard wall-mount bracket is included. 2 electricians can easily install it in 1–1.5 hours. We email a step-by-step PDF guide.
What is the warranty period?
3 years comprehensive warranty on motor + blower + control panel. Genuine spares dispatched Pan-India in 24–48 hrs.
Is a door sensor or remote available?
No remote is supplied — the unit is controlled by its built-in High/Low 2-speed switch. An automatic door sensor is available as an optional accessory.
What will the HSN code and GST rate be?
HSN 8414 59 10, GST 18%. We provide a full tax invoice with IRN and an e-way bill — ITC fully claimable.
How loud will it be in the kitchen?
4 ft Aluminium Premium: ~65 dB at 1m — well within the OSHA comfort range for kitchens, restaurants and retail.
Is there a discount on bulk orders?
Yes. Dealer pricing on 5+ units, project pricing on 25+ units. WhatsApp +91 9997778202 — send your BOQ for a same-day quote.
Will it work for a cold storage or freezer room?
Standard indoor models are for 0°C+ environments. For cold storage (-20°C) an industrial low-temp custom variant has to be ordered — available on a custom quote.
What is the power consumption per month?
240 W x 10 hrs/day x 30 days ≈ 108 kWh/month. ₹8/unit, that is ~₹860/month operating cost — great value against the insect and AC-loss savings.
Will a spare blower / motor be available?
Yes. Single-shaft + double-shaft motor, tangential blower, housing covers — all dispatched Pan-India in 24–48 hrs. HSN 8414 90 30.
Do you do multi-door installations for malls / showrooms?
Yes, we do. Site visit + BOQ + commissioning are free in Delhi NCR; for other cities travel cost is charged at actuals. The project team coordinates on WhatsApp.
Standard or Premium / Advanced — which is better?
All three give the same airflow and wattage for a given size. Standard — entry-grade components, 1-year warranty. Premium — higher-grade copper motors, quieter, 3-year warranty. Advanced — industrial-grade build for 24×7 duty, 5-year warranty.

❓ Frequently Asked Questions
🔧 How long does it take to install a 4 feet Premium Aluminium air curtain?
Approximately 60-90 minutes for a standard above-door horizontal mount. The 4-feet unit weighs about 12.0 kg — 30% lighter than CRCA equivalent — so two-person mounting is straightforward up to 3.5 m ceiling height. Chronovex provides a free installation diagram with every order, and our technical helpline (+91 9997778202) walks your electrician through wiring (single-phase 230V/50Hz) if needed.
💰 What is the running cost in rupees per hour?
At 240 W power draw and Rs 8 per kWh commercial electricity rate, the running cost is approximately Rs 1.92 per hour on high speed. For a typical 10-hour retail day that’s Rs 19.2. Compare with the AC load reduction (15-25% lower compressor cycling) which typically saves Rs 48–Rs 77 per day on AC electricity — net positive within 12 months.
⚖️ Why choose Premium Aluminium over Standard or Advanced?
Premium sits in the middle tier. All three series give the same airflow and wattage and have a High/Low switch. Versus Standard: Premium uses a higher-grade copper-wound motor, blower and housing for extended daily operation (8–10 year life vs 3–5) and carries a 3-year warranty (Standard 1-year). Versus Advanced: Premium costs less; Advanced uses industrial premium-grade parts for 24×7 duty (15–20 year life), includes a free automatic door sensor and carries a 5-year warranty.
⏱️ What is the payback period from AC electricity savings alone?
Typical payback is 12 months for a 4-feet unit at a continuously-operated entrance (10+ hours/day). The air curtain reduces AC compressor cycling by 15-25%, which translates to roughly Rs 58–Rs 96 per day in saved AC electricity in tropical India. Verified across deployments in Mumbai showrooms, Chennai restaurants, Bengaluru retail outlets, and Pune office lobbies.
🧾 What is the HSN code, GST rate, and tax invoicing?
HSN code is 8414 59 10 (Industrial fans and blowers — air curtains category). GST rate is 18% IGST / CGST+SGST. Every Chronovex invoice is GSTR-2B compliant with e-invoice IRN and QR code embedded, so your CA can claim Input Tax Credit automatically through GSTN reconciliation. We are a regular GST-registered manufacturer with GSTIN visible on every invoice.
🛠️ What warranty and after-sales support does Chronovex provide?
Standard warranty is 3 years on motors and electrical components. Extended AMC contracts up to 5-7 years are available at the time of purchase. For after-sales support, WhatsApp +91 9997778202 or email support@chronovex.in — typical response time is under 2 hours during business hours, pan-India spare parts ship the same day.
