Leading Motorised Roof Ventilator Exporter & Supplier in Qatar
Vayuvents Pvt. Ltd. has been manufacturing industrial fans and blowers at our Mumbai works for over two decades. We export our complete motorised roof ventilator range to Qatar with competitive FOB pricing and complete export documentation.
Qatar is the world's largest LNG exporter, with QatarEnergy's North Field expansion programme representing the world's single largest LNG development project. Ras Laffan Industrial City hosts QatarEnergy, Qatar Petroleum, and dozens of international EPC contractors, all requiring industrial ventilation equipment.
LNG liquefaction trains at Ras Laffan require heavy-duty centrifugal blowers for combustion air and ventilation. High-temperature hot air blowers are needed for instrument drying and heat tracing support. Large-scale construction projects across Qatar need axial fans and motorised roof ventilators for workshop heat extraction.
Why Qatar buyers choose Vayuvents Pvt. Ltd.: Vayuvents exports to Qatar through Hamad Port with full QatarEnergy and EPC contractor-compatible commercial documentation. USD invoicing available. Products are tested to international standards and supplied with calibration and test certificates.
Types of Motorised Roof Ventilators Exported to Qatar
Qatar's LNG and related sectors demand a range of configurations. We supply the following motorised roof ventilator variants to Qatar.
Standard Motorised Roof Ventilator
Axial impeller driven by roof-mounted motor — simplest, most common configuration for factory heat extraction.
Centrifugal Roof Exhaust Fan
Centrifugal impeller for higher static pressure applications — used where long internal ductwork is connected.
High Temperature Roof Ventilator
High-temp motor and bearing arrangement for foundry, forge, and kitchen exhaust at elevated temperatures.
SS Construction Roof Ventilator
Stainless steel body and impeller for corrosive environments — chemical plants, pharma, and coastal factories.
Access Door Roof Ventilator
Integrated access hatch in the base for inspection of internal ductwork from within the roof unit.
VFD-Ready Roof Ventilator
Variable frequency drive compatible motor winding for energy-efficient speed control — reduces power in low-load seasons.

Features of Our Motorised Roof Ventilators
- Direct-drive motor eliminates belts and pulleys — no belt slippage, no periodic belt replacement
- Weatherproof motor with IP55 enclosure as standard for outdoor roof mounting
- Birdproof wire mesh guard prevents nesting and debris ingress into the fan throat
- GI, aluminium, and SS body options to match building structure and process environment
- Rainhood as standard — prevents rain ingress into the factory during fan-off periods
- Low-profile design minimises wind load and visual impact on the building roofline
- Thermal overload protection built into motor starter for safe unattended operation
- Available with manual or automatic thermostat-controlled on/off operation
- Works performance-tested prior to dispatch with airflow measurement certificate
Benefits of Motorised Roof Ventilators
| Benefit | Description |
|---|---|
| Direct Heat Removal | Removes hot air at the highest point in the building — most efficient location for heat extraction by buoyancy. |
| Reduced Cooling Load | Lowering factory ambient temperature reduces the load on air conditioning and spot coolers significantly. |
| Fume & Smoke Clearance | Clears welding fumes, smoke, and VOC vapours from the building faster than wall-mounted exhaust fans. |
| Low Maintenance | Direct-drive construction and IP55 motors minimise maintenance requirements to periodic cleaning and inspection. |
| Worker Comfort | Improved factory air temperature and air quality directly improves worker productivity and reduces heat-stress incidents. |
| Energy Efficient | Thermostat-controlled auto operation runs the fan only when needed — significantly reduces running hours and power bills. |
