❓ Frequently Asked Questions
Which air curtains does the double-shaft-motor fit?
The double-shaft-motor is engineered for Chronovex air curtains across the Standard, Premium, and Advanced series (CRCA / Aluminium / SS304 body variants). It also fits most pan-India third-party brands with similar architecture (Almonard, Glamair, Crompton legacy units, Bajaj Industrial, etc.) where the shaft dimension, mounting points, and electrical rating match. Send a photo of your existing part on WhatsApp +91 99977-78202 for fit confirmation before bulk PO — we will verify against your serial number.
How do I know when the motor needs replacement?
Motors typically last 25,000–30,000 hours (~3–4 years 24x7). Replace when you observe: increased run-noise or rumble, motor housing running hotter than ~70°C in normal operation, intermittent stops requiring manual restart (winding insulation failing), or visible black soot near vents (over-heated insulation off-gassing). Always replace bearings at the same time — sintered-bronze bushes are a service item.
What is the price-difference between genuine OEM and unbranded marketplace replacements?
Marketplace generics typically price at 40–60% of OEM. The real cost difference shows up at the service call 6–12 months later when the wrong-spec part fails and damages adjacent components. A ₹300 cheap motor that fails and destroys a ₹1,800 blower has cost ₹2,100 total versus an OEM motor at ₹800 that lasts 3 years. For AMC contractors managing 50+ installs, the OEM premium is offset within the first quarter by reduced repeat service-call rate. We also supply with declared electrical ratings and traceable thermal-cutout calibration, which marketplace generics often misrepresent.
How is the double-shaft-motor priced for AMC contractors and service workshops?
Retail (1–9 units) at standard list price; bulk (10–49 units) at ~10–15% discount; AMC stocking pack (50+) at workshop-level pricing with consignment-stock options for multi-location contractors. We also offer emergency-spare overnight-courier dispatch from our Noida facility for critical-spare needs. Send your typical monthly consumption volume on WhatsApp +91 99977-78202 for a custom AMC pack quote.
What HSN, GST rate, and tax-invoice format do you provide?
HSN 8414 90 12 · GST 18%. Air-curtain parts and accessories fall under HSN 8414 90 12 in Chapter 84 (parts of fans / air-conditioning equipment). Every invoice carries IRN, signed QR (e-invoice as per CBIC mandate for B2B above the prescribed turnover threshold), our GSTIN, and HSN — fully eligible for buyer-side GSTR-2B auto-reconciliation. Input Tax Credit (ITC) is admissible for registered B2B buyers using these parts in the course of business.
What warranty do you provide on spare parts and how do I claim?
6-month manufacturer warranty on the double-shaft-motor from invoice date covering manufacturing defects. Wear-and-tear (bearings, lens haze, ABS yellowing in unusual UV-exposure conditions) is excluded. Send service requests on WhatsApp +91 99977-78202 with photo + original invoice; we respond within one business day. For AMC contractors we operate a fast-track defective-return scheme — ship the defective part back and we courier the replacement within 48 hours.

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.

📖 Which air curtains does this motor fit?
This double shaft ac induction motor is the factory-fit motor used in the following Chronovex air curtain models. If your air curtain is in this list and the motor has failed, this is the correct OEM replacement.
| Compatible Chronovex air curtain | Wattage |
|---|---|
| Metal Standard 5ft | 320W |
| Metal Standard 6ft | 360W |
| Metal Standard 7ft | 440W |

Note: If your air curtain is a Chronovex unit not listed above (older model, custom build, or larger industrial size), please contact our service team with your invoice number or unit serial — we will confirm the correct motor part number for you before you order.
🔧 Replacement & installation notes
- Isolate power — switch off the air curtain at the wall and lock the breaker. Wait 60 seconds for capacitor discharge.
- Open the unit — remove the front grill (4–6 self-tap screws depending on model size). Set the grill aside on a clean surface.
- Disconnect wiring — note the existing wiring colour code (typically red = live, black = neutral, green = earth, blue = capacitor). Take a photo before disconnecting.
- Remove old motor — unscrew the 4 mounting bolts holding the motor cradle to the chassis. Slide motor out, leaving the blower wheel(s) on the shaft until the motor is on the bench.
- Transfer blowers — loosen the blower hub grub-screw(s), slide blower(s) off the failed motor shaft, then slide onto the new OEM motor shaft. Retighten grub-screws to factory torque.
- Refit motor cradle — mount the new motor in the cradle, re-bolt to chassis. Ensure shaft is square to the airway (mis-aligned shaft causes blower vibration).
- Reconnect wiring — reattach in the same colour-code order. Tighten terminal screws fully — a loose neutral is the #1 cause of repeat motor failures.
- Test — close grill (4–6 screws), restore power, run the unit on Low for 5 minutes, then High for 5 minutes. Confirm smooth start, no rattle, full airflow.
⚠️ Professional installation recommended. If you are not comfortable with electrical work, please contact a qualified electrician or the Chronovex service network in your city. Improper installation will void the 6-month warranty.
❓ Frequently asked questions
Is this OEM or a market spare?
This is a genuine Chronovex OEM replacement motor. It comes from the same factory production line where the original air curtain is made. Cheaper Chinese or aluminium-winding clones are available in the market (typically 30–40% cheaper), but their lifespan is half and they come with no warranty. This is the original, with a 6-month warranty.
How does the warranty work?
6-month warranty from the invoice date — manufacturing defects only. A burnt coil due to water ingress, a voltage spike (above 270V) or a stalled rotor caused by a blocked blower is not covered. For a warranty claim, courier the original invoice + a photo of the failed motor to Noida HQ. For approved claims the replacement motor is dispatched within 5–7 working days.
Can I install it myself?
If you have basic electrical experience (you understand the wiring colour code and can isolate power), then yes — following the 8-step guide above, installation takes 30–45 minutes. But if you are not a professional electrician, please call a qualified electrician or contact the Chronovex service network — on-site service is available within 48 hours in Tier-1 cities.
Which air curtain models does this motor fit?
The complete list is in the fitment table above. If your air curtain is not listed there — an older Chronovex model, a custom industrial build or an imported unit — please first confirm with the service team using the invoice number or unit serial. Ordering the wrong motor voids the warranty and makes installation difficult.
Do you offer bulk order discounts and AMC vendor pricing?
Yes. 8–12% discount on 10+ units, a 15% slab on 25+. AMC vendors and authorised Chronovex service partners get a dedicated pricing tier with extended 60-day payment terms (subject to credit approval). Contact the sales team through the product page form for an actual bulk quote.
What is the HSN code? GST + invoice details?
HSN 8414 90 12 (parts of fans / air curtains / blowers — industrial). GST 18%. Full tax invoice provided for ITC claim. E-way bill auto-generated for B2B GST-registered buyers on shipments above ₹50,000. Service partners and AMC vendors get a separate vendor code for consolidated monthly billing.
