FAQs

1. What is an Air Handling Unit (AHU) and how does it work?

An Air Handling Unit (AHU) is an HVAC equipment designed to circulate, filter, cool, heat, and condition air before distributing it throughout a building. It consists of fans, filters, cooling/heating coils, dampers, and control systems. AHUs are widely used in hospitals, pharmaceutical plants, commercial buildings, food processing units, and industrial facilities to maintain indoor air quality and temperature.

2. What is the difference between an AHU and an FCU?

An AHU handles fresh air and larger volumes of conditioned air for multiple zones, whereas an FCU (Fan Coil Unit) primarily recirculates indoor air for individual rooms. AHUs are commonly used in industrial and commercial HVAC systems, while FCUs are preferred for hotels and residential buildings.

3. Why should I choose a Double Skin Air Handling Unit?

Double Skin AHUs provide superior thermal insulation, reduced noise levels, higher structural strength, improved energy efficiency, and better hygiene compared to single skin units. They are ideal for pharmaceutical, healthcare, food processing, and cleanroom applications.

4. Which industries commonly use Air Handling Units?

Air Handling Units are extensively used in:
• Pharmaceutical Manufacturing
• Hospitals
• Food & Beverage Plants
• Chemical Industries
• Hotels
• Commercial Buildings
• Warehouses
• Data Centers
• Electronics Manufacturing
• Cleanrooms
These industries require precise temperature, humidity, and air quality control.

5. How do I select the right Air Handling Unit capacity?

AHU capacity depends on airflow (CFM), cooling load, room dimensions, occupancy, heat load, filtration requirements, and application. Consulting an experienced AHU manufacturer helps ensure accurate sizing for maximum efficiency and lower operating costs.

6. What are the advantages of a Treated Fresh Air Unit (TFA)?

A Treated Fresh Air Unit supplies fresh outdoor air after filtering and conditioning it to maintain indoor air quality, reduce contaminants, and improve occupant comfort. TFAs are commonly installed in hospitals, offices, malls, and pharmaceutical facilities.

7. Why are HEPA filters important in cleanroom HVAC systems?

HEPA filters capture up to 99.97% of airborne particles as small as 0.3 microns. They are essential for pharmaceutical manufacturing, hospitals, laboratories, electronics production, and cleanrooms requiring contamination control.

8. What is the difference between a Cleanroom HVAC system and a standard HVAC system?

Cleanroom HVAC systems are specially designed to control airborne particles, pressure differentials, humidity, and temperature according to ISO 14644 standards. Standard HVAC systems primarily focus on thermal comfort and ventilation.

9. How often should an Air Handling Unit be serviced?

Routine preventive maintenance is recommended every 3–6 months depending on operating conditions. Maintenance includes filter replacement, coil cleaning, fan inspection, motor servicing, belt alignment, and airflow testing to ensure optimum performance.
