❓ Frequently Asked Questions

How long does installation take for the 4 feet Standard Aluminium air curtain?
Installation takes 2-3 hours by a 2-person team for a 4 ft (1220 mm) aluminium-body unit — lighter weight makes it faster than CRCA equivalent. Includes wall/ceiling bracket mounting at 2.2-2.5 m height, 220 V single-phase wiring with MCB, and ON/OFF switch commissioning. Doorway pre-checks: lintel structural support ≥ 15 kg, clean 230 V supply (PF > 0.85), and 0.3-0.5 m horizontal clearance.
What is the operating cost of the 4 feet Standard Aluminium air curtain?
At 240 W rated draw and Rs 8/kWh commercial tariff, the 4 ft Standard Aluminium unit costs roughly Rs 1.92/hour. Typical retail/office duty cycle is 6-9 hours/day, giving Rs 13-Rs 17/day. Without 2-speed control the unit runs at full power throughout duty cycle — if your doorway needs variable airflow throughout the day, consider the Advanced Aluminium variant instead.
Why choose Standard Aluminium over Advanced Aluminium?
Standard Aluminium is the right pick when: (1) <strong>budget is the primary constraint</strong> — Standard tier saves ~25% on capex vs Advanced; (2) <strong>doorway duty cycle is consistent</strong> — you don't need 2-speed switching; (3) <strong>simple ON/OFF is preferred</strong> — no IR remote or digital panel to train staff on; (4) <strong>humid/coastal protection is critical</strong> — you still get aluminium body benefits over CRCA. Choose Advanced Aluminium if you need 2-speed control, IR remote, digital panel and auto-restart.
What is the payback period from AC savings?
In typical Indian retail/F&amp;B doorways with HVAC running 8-10 hours/day, the 4 ft Standard Aluminium unit pays back in 8-10 months from reduced HVAC load alone (10-18% AC kWh saved at full-speed operation). Lower capex than Advanced tier accelerates effective payback. Verified across deployments in Noida, Gurugram, Mumbai and Chennai SME retail clusters.
What is the HSN code and GST rate?
HSN code is <strong>8414 59 10</strong> (fans &mdash; other; industrial). GST is <strong>18%</strong> (CGST 9% + SGST 9% intra-state, or IGST 18% inter-state). GSTR-2B ITC available against B2B GSTIN invoices &mdash; we issue full e-invoice with IRN and QR for orders above Rs 5 lakh as per CBIC mandate.
Does it ship with a warranty?
Yes &mdash; 12-month standard manufacturer warranty against motor and electrical defects from invoice date. Aluminium body carries 5-year corrosion warranty against pitting/oxidation under normal operating conditions. Pan-India service via authorized partners in 18 cities.

📖 Product Overview & Buyer Guide

The Chronovex 4 ft Aluminium Standard Air Curtain is purpose-built for storefront-class single-door entries (up to 1.2 m / 48 inch) — a category that includes most retail shops, clinics, mid-size showrooms, restaurants, cafes and standard office entrances across India. With a 240 W twin-motor + 4-blower setup delivering 2,000 CFM peak airflow, this unit creates a strong air barrier against flies, dust and conditioned-air loss at ~₹15/day running cost on high mode.

🏅 Manufacturing & Quality

Chronovex Industries Pvt. Ltd. manufactures every air curtain at our ISO 9001:2015 certified facility in Noida, Uttar Pradesh. Each 4 ft Aluminium Standard unit passes 12 QC checkpoints — dual-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 Standard, Not Premium

The 4 ft Standard uses a manual 2-step speed switch (high / low) — simple, reliable, low-maintenance. The 4 ft Premium adds an IR remote, door-position sensor (auto on/off), and a slightly quieter motor profile. For a high-footfall shop where the door is constantly opening, Standard is more cost-effective. For showrooms / banks / clinics that want hands-free operation, Premium pays back its small price premium in convenience.

❓ Frequently Asked Questions

Q. Is 4 ft enough for a standard shop door?
Yes — most Indian shop / showroom doors are 1.0–1.3 m wide. The 4 ft unit covers up to 1.3 m on high mode. For doors above 1.5 m, consider the 6 ft Metal variant.
Q. What is the difference between 4 ft Standard and 4 ft Premium?
Standard (this unit) has a manual 2-speed switch. Premium adds a remote control, IR door sensor (auto on/off), and a slightly quieter motor. Both have the same body size.
Q. Can I run it on a 1.5 ton AC inverter?
No — air curtains have an inductive starting current. Use a dedicated 5 A 220 V outlet. For backup, use a 300 W+ inverter that handles inductive loads.
Q. How heavy is it? Can I wall-mount it alone?
~11.5 kg. We recommend 2-person installation — one to hold, one to drill / mount. The included bracket kit is rated for 20 kg loadout.
Q. Does it work in coastal humid climates?
Yes — the aluminium body is powder-coated for corrosion resistance. For heavy salt-spray zones (within 1 km of sea), the 6 ft Metal variant has a slightly thicker coating.
Q. What is the warranty claim process?
WhatsApp the unit serial number + invoice + a 30-second video of the issue to +91 9997778202. We dispatch a replacement within 48 hrs if the unit is under warranty.
Q. Do you ship to Tier-2 / Tier-3 cities?
Yes — pan-India via Delhivery / DTDC / VRL surface freight. 3–5 days for metros, 5–7 days for smaller towns.
Q. Is bulk pricing available for hotel / retail chains?
Yes — slab-based volume pricing on orders of 10+ units. WhatsApp your project quantity for a B2B rate card.
