RECYCLED AIR UNIT ( RAU )
Recycled Air Unit (RAU) Supplier in India – Eco-Friendly HVAC Air Recovery Solutions | Compress India
Compress India is a trusted supplier of high-quality Recycled Air Unit (RAU) systems used for indoor air recovery, energy saving, and ventilation enhancement. RAU systems help improve air quality by reprocessing return air and circulating it efficiently inside buildings. These units work in conjunction with Air Handling Units (AHUs) and Fan Coil Units (FCUs) to create comprehensive HVAC solutions.
We do not recycle AC units — we only supply RAU HVAC systems. For customers searching terms like "window air conditioner recycling near me", "scrapping air conditioners", "old air conditioner near me", or "portable air conditioner recycling", we clarify that Compress India only supplies new RAU ventilation units.
What Is a Recycled Air Unit (RAU)?
Understanding Recycled Air Unit Systems
A Recycled Air Unit (RAU) is an HVAC device designed to filter, recirculate, and improve the quality of indoor air. RAUs support energy-efficient ventilation by reducing fresh-air load on chillers, AHUs, and HVAC systems. While many people search for recycling air conditioners, recycling window air conditioners, or recycling air conditioners for money, RAUs serve a different purpose — they recycle indoor air, not old AC units.
Types of Recycled Air Units We Supply
Standard Recycled Air Unit – Efficient air recirculation for offices, malls, hospitals, and commercial HVAC systems with reliable indoor air management.
High-Efficiency Filtration RAU – Includes multi-stage filters to clean indoor return air before redistribution, ensuring superior air quality.
Energy Recovery RAU Units – Improves indoor air quality while reducing load on cooling systems through efficient air recycling technology.
Ceiling-Mounted & Industrial RAU Systems – Includes ceiling-mounted RAU units for confined spaces and industrial RAU systems for factories and production environments.
Compress India supplies multiple types of Recycled Air Units (RAU) to meet commercial, industrial, and HVAC requirements. All units are carefully selected to ensure efficient indoor air recycling, improved air quality, and reduced HVAC energy consumption for diverse building environments.

RECYCLED AIR UNIT ( RAU )
What is a Recycled Air Unit? A "recycled air unit" in HVAC terminology describes a system that predominantly circulates and reuses the existing air within a building, rather than continuously introducing fresh outside air. Essentially, it "recycles" the indoor air by filtering and conditioning it before redistributing it throughout the space. This approach is often employed to conserve energy by reducing the necessity to heat or cool large amounts of outside air.
- Energy efficiency: Conserves energy by reducing HVAC workload through minimal outside air treatment.
- Mixing chamber: Allows controlled mixing of fresh outside air with recirculated air to maintain indoor air quality.
- Applications: Ideal for environments needing stable temperature and humidity, such as cleanrooms, laboratories, and high-heat-generating facilities.
