❓ Frequently Asked Questions

What is the HSN code and GST rate for air curtains in India?
Air curtains are classified under HSN 8414 59 10 with GST at 18%. This is the official tariff line per CBIC; the same HSN applies whether you buy a 2-feet residential unit or a 7-feet industrial unit.
Which BIS standard applies to air curtains sold in India?
BIS IS 12053 is the Indian standard that defines air-curtain test methods, velocity profiles and labelling requirements. Chronovex tests every Standard, Premium and Advanced series unit against the IS 12053 method.
What is the warranty on Chronovex air curtains?
Chronovex offers 1-year warranty on the Standard series, 3-year warranty on the Premium series and 5-year warranty on the Advanced series, covering motor and electrical components against manufacturing defects. Full terms are in the Warranty Policy.
How do I pick the right air curtain length for my door?
Match the air-curtain length to the door width. For a 3-feet (900 mm) door pick a 3-feet unit; for double doors pick the next size up or install two units side-by-side. Mounting height should not exceed 3.0 m for Standard, 3.5 m for Premium, 4.5 m for Advanced.
Is GST charged on B2B air-curtain invoices?
Yes — 18% GST is charged on all B2B invoices and is fully claimable as input tax credit (ITC) against your GSTIN, provided the supply is used for business purposes per Section 16 of the CGST Act.

Air Curtain 5 Feet · SS304 Stainless · Premium

IR sensor + remote SS304 stainless air curtain — designed for pharma labs, hospital wards and food-grade R&D entries.

🔎 At a glance

Chronovex SS304 stainless body air curtains — built in Noida for India’s food, pharma and clean-environment doorways. The 5 Feet Premium variant covers a 1.5 m door with 2,500 CFM peak airflow, 320 W draw, 3-motor / 5-blower setup, and a non-corrosive 1.0 mm SS304 stainless body that handles wash-down, salt-laden coastal air, dairy condensate and pharma clean-down chemistries that destroy powder-coated steel. ISO 9001:2015. Full ITC GST invoice. Pan-India dispatch from Noida.

🔧 Why SS304 over powder-coat steel

  • 🧼 Wash-down ready — SS304 survives daily caustic/sanitiser wash-down in F&B prep, dairies, meat processing and pharma corridors. Powder coat chips and rusts within 6–12 months in the same environment.
  • 🧫 Food-grade hygiene — FSSAI / HACCP-friendly. No paint flakes shedding into food zones, no organic substrate for microbial colonies.
  • 🌊 Coastal & humid — Mumbai, Chennai, Kochi, Vizag coastal industries see powder-coat fail in 12 months. SS304 lasts 10–15 years.
  • ⚡ Same airflow envelope — 2,500 CFM peak, 14 m/s outlet velocity, 2.4 m jet reach — matches the metal-body line spec-for-spec.
  • 🔌 Industrial duty — 3-motor, 5-blower setup rated for 18-hour continuous operation, ≤ 66 dB(A) at 1 m.

  • 🏬 Coastal industries — Mumbai, Chennai, Kochi, Vizag, Goa plants where powder-coat fails in <12 months

🔧 Installation

Wall-mount above doorway at 2.4 m height — brackets included. Requires 220 V single-phase dedicated MCB. Licensed electrician / MEP contractor recommended. Same-day dispatch from Noida — Delhi NCR delivery 1–2 days, metros 3–5, tier-2/3 5–7 days.

❓ FAQ

Is SS304 actually food-grade? Yes — SS304 (18% Cr, 8% Ni) is the standard food-contact grade specified by FSSAI, HACCP and US FDA for direct-contact food equipment. The body is brushed-finish, non-porous, and survives daily caustic / sanitiser wash-down.

How is this different from the SS304 Premium "powder-coat" variant? This unit has a true SS304 stainless body throughout — not steel with a stainless-look coating. Worth the premium if your environment has wash-down, salt-air, condensate or pharma clean-down chemistries.

Do you ship pan-India with GST invoice? Yes — full ITC GST invoice on every order, dispatch from Noida via verified courier / transport partners.

What is the warranty? 1 year on motors, 1 year on IR sensor & remote.


Frequently Asked Questions

Find answers to common questions about this product

A trained 2-person team installs the 5-feet (1525 mm) Premium SS304 unit in 60–90 minutes on a standard masonry / RCC lintel. We provide free pan-India installation guidance over WhatsApp video call and can dispatch our service partner in 80+ cities. SS304 mounting brackets and stainless hardware ship included.

At 320 W rated draw on 230 V single-phase and the commercial industrial tariff of ₹8/kWh, the 5-feet Premium SS304 air curtain costs approximately ₹2.6/hour to run. Over an 8-hour shift that is roughly ₹20.8, which is typically 60–80% lower than the cost of cooled / dehumidified air lost through an open door.

All three share the same SS304 (AISI 304) food-grade shell and IP55 rating. Premium-Series uses higher-torque copper-winding premium motors and tighter blower balancing for ≤ 65 dB acoustics — specified for hospital & pharma sites. It is single-speed (no 2-speed switching, no IR remote, no digital panel). Advanced-Series adds 2-speed H/L operation, IR remote, digital LED panel, auto-restart and EC-class motors (PF > 0.93, ≤ 60 dB). Standard SS304 is the value tier at 68–70 dB with economy motors. Pick Premium SS304 when you need pharma / hospital acoustics without paying for remote-controlled 2-speed.

Typical payback is 6 months in conditioned-air environments. The unit blocks ≈ 80–85% of cooled-air loss through an open 5-feet (1525 mm) doorway; an HVAC system serving a 1500–3000 sqft area at ₹12/sqft/month conditioning cost recovers the air-curtain CapEx in 6 months. Add hygiene savings (fewer flies, lower pest-control bills under FSSAI / Schedule-M audit) and payback typically falls below 6 months.
