❓ 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 <strong>8414 90 12</strong> · GST <strong>18%</strong>. 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 <strong>+91 99977-78202</strong> 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.

🔧 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
Yeh OEM hai ya market spare?
Yeh genuine Chronovex OEM replacement motor hai. Same factory production line se aata hai jahan original air curtain banta hai. Market mein cheaper Chinese ya aluminium-winding clones milte hain (typically 30–40% sasta) but unka lifespan half hota hai aur warranty bhi nahi milti. Yeh original hai with 6-month warranty.
Warranty kaisa milta hai?
6-month warranty from invoice date — manufacturing defects only. Burnt coil due to water ingress, voltage spike (above 270V) ya blocked blower ke karan stalled rotor coverage ke bahar hain. Warranty claim ke liye original invoice + photo of failed motor courier karna hota hai Noida HQ ko. Approved claims mein replacement motor 5–7 working days mein dispatch ho jata hai.
Installation khud kar sakte hain?
Agar aapko basic electrical work ka experience hai (wiring colour code samajhte ho, power isolation kar sakte ho), to haan — upar wala 8-step guide follow karke 30–45 minutes mein installation ho jata hai. Lekin agar aap professional electrician nahi ho, please qualified electrician ko bulaye ya Chronovex service network ko contact kare — Tier-1 cities mein on-site service 48 hours mein available hoti hai.
Kaunse air curtain models mein lagta hai yeh motor?
Upar fitment table mein complete list di hui hai. Agar aapka air curtain wahan listed nahi hai — older Chronovex model, custom industrial build, ya import unit — please pehle service team se confirm kar lo invoice number ya unit serial ke saath. Wrong motor order karne se warranty void ho jaati hai aur installation mein difficulty aati hai.
Bulk order discount aur AMC vendor pricing milta hai?
Haan. 10+ units par 8–12% discount, 25+ par 15% slab. AMC vendors aur authorized Chronovex service partners ke liye dedicated pricing tier hai with extended 60-day payment terms (subject to credit approval). Sales team se contact karo through the product page form for actual bulk quote.
HSN code kya hai? GST + invoice details?
HSN 8414 90 12 (parts of fans / air curtains / blowers — industrial). GST 18%. Full tax invoice provided for ITC claim. B2B GST registered buyers ke liye e-way bill auto-generated for shipments above ₹50,000. Service partners aur AMC vendors ke liye separate vendor code allotted hota hai for consolidated monthly billing.
