Description
Wind-Driven FRP Rooftop Air Ventilator Manufacturer in Gujarat
Nikunj Fibre Glass is a leading manufacturer and supplier of FRP Air Ventilators (Wind-Driven Rooftop Turbo Ventilators) based in Vapi, Gujarat. Operating entirely without electricity by harnessing natural wind energy and thermal convection (stack effect), our FRP roof ventilators continuously exhaust hot stale air, toxic chemical fumes, smoke, and moisture from industrial sheds and warehouses.
Unlike standard aluminum or stainless steel ventilators that rapidly oxidize and fail in corrosive chemical factory atmospheres, our ventilators are fabricated from premium UV-resistant fiberglass composite, delivering decades of maintenance-free ventilation.
Key Features & Advantages
- Zero Electricity Operating Cost: 100% wind-driven and thermodynamic convection; operates 24/7 without consuming power.
- Complete Acid & Fume Immunity: Unaffected by acidic factory fumes, sulfur dioxide, chlorine, or humidity that destroy aluminum vents.
- Heavy-Duty Precision Bearings: Sealed double-row stainless steel / ceramic bearings ensure effortless rotation even in gentle breezes (less than 2 km/hr).
- Weatherproof & Rain-Deflecting: Aerodynamically curved vane geometry prevents rainwater entry under heavy monsoon downpours.
- Custom Molded FRP Base Plate: Matching corrugated or trapezoidal profile base sheets engineered for leak-proof installation on all roof profiles.

- ✅ Warehouses & Logistics Sheds: Prevents heat accumulation beneath metal roofs and protects stored goods.
Frequently Asked Questions (FAQ)
Q1: Does rain water leak through the spinning ventilator vanes?
No, the curved vane profile creates an outward centrifugal barrier during rotation that prevents rain entry, and internal drain channels redirect moisture onto the roof sheet.
Q2: How many FRP ventilators are required for an industrial shed?
Our technical team calculates the exact number based on shed volume, internal heat dissipation, and recommended air change rate per hour (typically 10 to 15 air changes per hour for chemical plants).
