Frequently Asked Questions About HVLS Fans
HVLS stands for High Volume Low Speed. These industrial fans move large volumes of air at low RPM, making them highly effective for cooling large spaces like warehouses and factories.
HVLS fans create cooling through gentle, high-volume airflow that promotes evaporation on the skin. This wind-chill effect can reduce perceived temperature by 5 to 8 degrees Celsius without lowering actual room temperature.
HVLS fans are used in warehouses, manufacturing plants, gymnasiums, dairy farms, railway stations, airports, community halls, churches, and any large indoor or semi-outdoor space above 5,000 square feet.
Austar HVLS fan prices in India range from ₹1.3 lakh for a 12-foot model to ₹3.5 lakh for a 24-foot variant, ex-factory from Ahmedabad. Final delivered price depends on freight, mounting hardware and installation scope.
Choose your HVLS fan size based on coverage area. A 12 ft fan covers about 6,000 sq ft, 16 ft covers 10,000 sq ft, 20 ft covers 16,000 sq ft, and a 24 ft Austar fan covers up to 22,000 sq ft. Use the Austar Cooling Calculator for a precise recommendation.
A minimum ceiling height of 14 feet is required for safe HVLS fan operation. Optimal performance is achieved between 18 and 30 feet. For higher ceilings, custom downrods of up to 12 feet can be supplied.
A standard Austar HVLS fan installation takes 4 to 6 hours per unit on site. End-to-end timeline from purchase order to commissioning is typically 7 to 14 days for any India location, with 4,500+ installations completed.
Austar HVLS fans consume 0.75 to 1.5 kW depending on size, costing roughly ₹3.5 to ₹7 per hour to operate at typical Indian industrial tariffs. Compared to running 15 to 20 conventional fans, this delivers 60 to 70% energy savings.
Austar provides a 5-year warranty on motor and gearbox plus a 1-year warranty on electrical components. Annual Maintenance Contracts are available pan-India through 8 service centers in Ahmedabad, Pune, Delhi, Bangalore, Chennai, Kolkata, Vapi and Guwahati.
Geared HVLS fans use a gearbox-driven motor offering high torque and lower upfront cost. Gearless HVLS fans use a PMSM motor that is quieter, maintenance-free, and around 15% more energy efficient. Both are manufactured by Austar Technologies.
No. Austar HVLS fans operate at under 45 decibels at 6 feet distance, which is quieter than a normal conversation. The low RPM design and helical gearbox eliminate the high-frequency noise found in older HVLS fans.
HVLS fans complement rather than replace air conditioning, but in non-AC industrial spaces they reduce perceived temperature by 5 to 8 degrees Celsius. Pairing HVLS with AC reduces HVAC load by 20 to 30%, delivering substantial summer electricity savings.
Yes, HVLS fans work effectively in semi-outdoor settings like loading docks, covered patios, agricultural sheds, and railway platforms. They should be sheltered from direct rain and high winds for longest service life.
HVLS fans need minimal maintenance. Recommended preventive servicing is twice a year for blade cleaning, gearbox oil check, and electrical inspection. Austar offers AMC plans starting at 4% of fan cost per year.
Yes, Austar HVLS fans are engineered with high-strength aluminum blades, secure double-mounting systems, retainer rings, and overload protection. All models are CE certified and meet international safety standards.
Austar Technologies is India's largest HVLS fan manufacturer with 4,500+ installations, 300 fans per month capacity, direct-from-factory pricing, 5-year warranty, and recognition by the Hon. CM of Gujarat at the Mahasanman event.
HVLS stands for High Volume Low Speed. These fans are designed to move a large volume of air efficiently while operating at low speeds. This unique design is highly effective for creating a cooling effect in large spaces.
HVLS fans create a cooling effect through the principles of air movement and evaporative cooling. By gently circulating a large volume of air at low speeds, they facilitate the evaporation of sweat on the skin, which makes people feel cooler.
HVLS fans are typically used in settings with large, open spaces. They are commonly found in warehouses, manufacturing facilities, gymnasiums, agricultural buildings, commercial spaces, and even outdoor venues.
The benefits of HVLS fans in industrial settings are manifold. They enhance air circulation, promote temperature equalization, and significantly reduce energy consumption. By reducing the need for traditional heating and cooling systems, they lead to substantial energy savings.
Yes, HVLS fans can be used in outdoor settings with the same effectiveness. They are often installed in open-air locations like patios, loading docks, and agricultural spaces to create a comfortable environment.
Absolutely. HVLS fans are known for their energy efficiency. By promoting natural cooling and reducing the reliance on traditional HVAC systems, they lead to considerable energy cost savings over time.
Austar Technologies HVLS Fans offer benefits such as energy savings, improved air circulation, temperature regulation, and enhanced comfort. They are ideal for large industrial and commercial spaces.
