❓ Frequently Asked Questions
How long does it take to install a 3 feet Standard SS304 air curtain?
Approximately 60-90 minutes for a standard above-door horizontal mount. The 3-feet SS304 unit weighs about 21.0 kg (heavier than aluminium because stainless steel is denser), so two-person mounting with proper lintel support is recommended up to 3.5 m ceiling height. Chronovex provides a free installation diagram and material test certificate (MTC) for the SS304 body on request — essential for FSSAI/USFDA audit dossiers. Technical helpline +91 99977-78202 walks your electrician through 230V/50Hz single-phase wiring if needed.
What is the running cost of this 3 feet Standard SS304 air curtain in rupees per hour?
At 200 W power draw and Rs 8 per kWh commercial electricity rate, the running cost is approximately Rs 1.6 per hour of single-speed operation. For a typical 14-hour kitchen or pharma cleanroom shift that's Rs 22.4. Compare with the HVAC load reduction (15-25% lower compressor cycling) plus the avoided cost of repeated CRCA/aluminium replacement in food-grade environments — net positive within 14 months on energy savings alone, even faster when factoring avoided FSSAI non-compliance penalties.
Why choose Standard SS304 over Aluminium or CRCA in food-grade or pharma environments?
SS304 grade 18/8 is the only food-safe and pharma-cleanroom-rated choice. FSSAI licensing requires food-contact-zone surfaces to be SS304 or better. USFDA audits flag CRCA and aluminium as non-compliant in formulation and packing zones. Schedule M / WHO-GMP mandates SS304 for primary product-contact areas. Aluminium handles general humidity but is not food-contact-rated. CRCA rusts within 12 months under chlorinated wash-down. SS304 stays inert indefinitely against acids, alkalis, salt spray, and steam-sanitation cycles. Standard tier gives you all that at ~25% lower price than Advanced SS304 (which adds 2-speed + IR remote + digital panel).
What is the payback period for a 3 feet Standard SS304 air curtain from energy savings alone?
Typical payback is 14 months for a 3-feet unit at a continuously-operated food-grade entrance (12-14 hours/day). The air curtain reduces HVAC compressor cycling by 15-25%, which translates to roughly Rs 67-Rs 112 per day in saved AC electricity. Add the avoided cost of replacing rusted CRCA every 12-18 months in food-grade environments and the payback can compress to under 8 months. Verified across deployments in Mumbai FSSAI kitchens, Hyderabad USFDA-audited pharma plants, and Anand dairy facilities.
What is the HSN code, GST rate, and tax invoicing for this Standard SS304 air curtain?
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. Material test certificate (MTC) for SS304 grade compliance is available on request — essential for FSSAI audit dossiers, USFDA inspections, and WHO-GMP documentation.
What warranty and after-sales support does Chronovex provide on Standard SS304 air curtains?
Standard warranty is 12 months on motors and electrical components, plus a 10-year shell warranty on the SS304 body against corrosion, pitting, and structural defects — industry-leading. Extended AMC contracts up to 5-7 years are available at the time of purchase. SS304 grade compliance MTC available on request for audit dossiers.

Hygienic SS304 stainless air curtain — ideal for kitchens, F&B prep, dairies and clean-room entries.
🔎 At a glance
Chronovex SS304 stainless body air curtains — built in Noida for India’s food, pharma and clean-environment doorways. The 3 Feet Standard variant covers a 0.9 m door with 1,500 CFM peak airflow, 200 W draw, 2-motor / 3-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 — 1,500 CFM peak, 14 m/s outlet velocity, 2.2 m jet reach — matches the metal-body line spec-for-spec.
- 🔌 Industrial duty — 2-motor, 3-blower setup rated for 18-hour continuous operation, ≤ 65 dB(A) at 1 m.

❓ 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 Standard "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 & electricals.
