In a proactive move to improve commuter comfort and tackle persistent ventilation challenges, the Delhi Metro Rail Corporation (DMRC) has installed High Volume Low Speed (HVLS) fans across several high-footfall underground stations. The initiative, launched in early September 2025, is part of DMRC’s broader strategy to enhance air circulation and reduce heat stress during peak hours and technical disruptions.
The first phase of the rollout includes 31 HVLS fans installed at Hauz Khas, Kashmere Gate, and Azadpur stations—three of the busiest interchange points in the Delhi Metro network. These fans are designed to circulate large volumes of air at low speeds, creating a steady breeze-like effect that significantly improves ambient conditions in enclosed spaces.
Key Highlights From The Ventilation Upgrade
- DMRC has installed 31 HVLS fans across three underground stations
- Hauz Khas received 18 fans, Kashmere Gate 8, and Azadpur 5
- The fans are energy-efficient, low-maintenance, and optimized for large indoor spaces
- The initiative follows recent passenger complaints during monsoon-related congestion
- Additional installations are planned based on station design and crowd density
Why HVLS Fans And Why Now
HVLS fans differ from conventional ceiling fans by using larger blades that rotate slowly to push air across wider areas. This technology is particularly effective in underground stations where natural ventilation is limited and air conditioning systems are often overwhelmed during peak hours.
- HVLS fans help maintain normal temperature and reduce humidity buildup
- They operate at lower energy consumption compared to traditional cooling systems
- The fans are ideal for high-density zones with limited vertical clearance
- DMRC selected stations based on passenger volume and interchange complexity
Station-Specific Implementation
The rollout prioritizes stations that serve as interchange hubs and experience frequent overcrowding. Hauz Khas, located on the Yellow and Magenta lines, has long struggled with heat retention due to its depth and structural layout. Kashmere Gate, connecting Red, Yellow, and Violet lines, sees over 250,000 passengers daily. Azadpur, a growing interchange between Yellow and Pink lines, has also faced ventilation bottlenecks.
- Hauz Khas: 18 fans installed across concourse and platform levels
- Kashmere Gate: 8 fans placed near entry gates and waiting zones
- Azadpur: 5 fans deployed in platform corridors and escalator areas
Commuter Experience And Feedback
The installation has already begun to show positive results, with passengers reporting improved air circulation and reduced discomfort during rush hours. DMRC has received favorable feedback through its mobile app and station feedback kiosks.
- Commuters noted better airflow and reduced stuffiness during peak congestion
- Elderly and differently-abled passengers reported easier breathing conditions
- DMRC plans to conduct thermal mapping to assess post-installation impact
Future Plans And Network Expansion
DMRC is evaluating additional stations for HVLS fan deployment, particularly those on the Blue, Pink, and Magenta lines. The second phase may include Rajiv Chowk, Central Secretariat, and Nehru Place, subject to structural feasibility and crowd analytics.
- Phase II rollout expected by December 2025
- Integration with smart ventilation systems under review
- DMRC exploring partnerships for energy-efficient retrofits across the network
A Breath Of Fresh Air For Delhi Metro
With over 60 lakh daily passengers and a network spanning 394 kilometers, Delhi Metro remains the backbone of urban mobility in the National Capital Region. The HVLS fan initiative reflects DMRC’s commitment to commuter well-being and operational innovation. As the city braces for extended monsoon and festive season crowds, these upgrades offer timely relief and set a precedent for sustainable infrastructure enhancements.
