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 15–20 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, dual-speed switch, and a remote control option make it the workhorse choice for retail floors, salons, clinics, branch offices and quick-service kitchens across India.

Key features
- 3-motor / 6-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.
- Heavy-duty CRCA steel body with epoxy-baked powder coating — resists humidity, salt-air corrosion and minor impact during cleaning.
- Pest, fly & dust barrier — the down-jet velocity at 15–20 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).
- Standard-Series electronics — tuned for reliable everyday use at retail price; for hotel lobbies, banquet entries & premium showrooms see our 4 ft Premium Series or 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: 3–7 working days dispatch from Noida; metro pin-codes typically deliver in 2–4 transit days, Tier-3 / North-East 5–9 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 ₹2.9/hour or roughly ₹950/month for a typical 10 AM–9 PM retail shift. Running on Low speed (~270 W) cuts that to roughly ₹720/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 — 12 months 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 99977-78202 or write to customercare@chronovex.in.

📖 Product Overview & Buyer Guide
In-depth buyer guide — why this tier, full specs, deployment cities, warranty & FAQs.
Chronovex 4 Feet Premium Series Aluminium Body Air Curtain — mid-tier industrial-grade door air curtain for Indian SME businesses needing reliable insect-fly-dust barrier with corrosion-resistant aluminium shell. Premium-grade copper-wound motors deliver 2000 CFM at high speed, throw distance 8-10 ft, ≤65 dB premium acoustics. HSN 8414 59 10, GST 18%, e-invoice ready.
🤔 Why Premium Aluminium over Standard or Advanced?
Premium tier sits between Standard (entry-level single-speed) and Advanced (2-speed + IR remote). You get higher-torque copper motors and quieter ≤65 dB operation than Standard, with the same corrosion-resistant aluminium body — but without the 2-speed / digital-panel / IR-remote premium of Advanced (which adds ~30% to price). Ideal for retail entrances, restaurants, clinics, showrooms, and office lobbies in coastal Mumbai, Chennai, Kochi, Goa where humid air corrodes CRCA but you don’t need flagship features.
📋 Quick Specs at a Glance
| Length: 4 feet (1220 mm) | Body: Premium-grade aluminium alloy, powder-coated, 30% lighter than CRCA — 5-yr shell warranty |
| Motors / Blowers: 2 copper-wound motors driving 4 centrifugal blowers | Power: 240 W @ 230 V / 50 Hz single-phase, PF >0.90 |
| Airflow: 2000 CFM (single-speed premium) | Throw distance: 8-10 ft vertical at full velocity |
| Noise: ≤65 dB(A) at 1 m — premium acoustics | Control: Wall-mounted ON/OFF switch (no IR remote / digital panel) |
| Mounting: Above-door horizontal, max 3.5 m ceiling height | Weight: approx 21.8 kg |
| HSN: 8414 59 10 · GST: 18% · Origin: Made in India (Noida) | Warranty: 12 months motors + 5-year aluminium shell against corrosion |
📍 Where Premium Aluminium air curtains work best
Deployed across India — anywhere salt-laden coastal air or monsoon humidity would corrode a CRCA shell within 18 months. Aluminium body resists pitting and oxidation indefinitely under normal indoor humidity.

❓ 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 21.8 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 99977-78202) 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 of single-speed operation. 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. Versus Standard Aluminium: Premium has higher-torque copper-wound motors (PF >0.90 vs 0.85), quieter ≤65 dB acoustics vs ≤70 dB, and longer 5-year body warranty vs 3-year. Versus Advanced Aluminium: Premium is ~30% cheaper because it skips the 2-speed switching, IR remote, digital control panel, and auto-restart features. Choose Premium when you want better-than-entry build quality and corrosion resistance, but don’t need flagship electronics — ideal for retail, restaurants, clinics, showrooms.
⏱️ 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 12 months on motors and electrical components, plus a 5-year shell warranty on the aluminium body against corrosion and pitting (industry-leading). Extended AMC contracts up to 5-7 years are available at the time of purchase. For after-sales support, WhatsApp +91 99977-78202 or email support@chronovex.in — typical response time is under 2 hours during business hours, pan-India spare parts ship within 48 hours.
