Frequently Asked Questions (FAQs)
What is an Air Handling Unit (AHU), and where is it used?
An Air Handling Unit is a key part of an HVAC (Heating, Ventilation, and Air Conditioning) system. It regulates and circulates air in buildings, cleanrooms, hospitals, laboratories, and industrial spaces. Ultrafil designs and manufactures AHUs for diverse industries across India, ensuring high air quality and energy efficiency.
What are air handling units (AHUs) used for?
AHUs manage heating, cooling, and ventilation, helping maintain the right temperature, humidity, and cleanliness. They are crucial for places that require controlled environments like pharmaceutical production, healthcare facilities, and electronics manufacturing.
What are the key components of an AHU?
The main components include fans, heating and cooling coils, air filters, dampers, and the supply and return air plenums. Together, these parts control airflow, temperature, humidity, and air cleanliness.
What types of accessories are available for AHUs?
Ultrafil supplies a full range of AHU accessories, such as filters, dampers, diffusers, heat exchangers, and control panels. These help improve air quality, system performance, and operational efficiency.
Can you provide Positive Pressure Units (PPU) and Negative Pressure Units (NPU)?
Yes. Ultrafil manufactures both PPU and NPU systems to control air pressure in sensitive spaces like cleanrooms, laboratories, and pharmaceutical areas, preventing cross-contamination.
Do you provide dehumidifiers for industrial and residential use?
Yes. We offer industrial-grade dehumidifiers for cleanrooms and manufacturing processes, as well as compact units for residential spaces. We supply options for locations like Hyderabad and for well-known brands such as IFB.
What are heat transfer coils, and why are they important in AHUs?
Heat transfer coils (including copper and spiral coil types) move heat between air and liquids in HVAC systems. They help maintain the right temperature and humidity for indoor comfort or process requirements.
Where can I find high-quality dampers, diffusers, and grills?
Ultrafil supplies durable dampers, diffusers, and grills for effective airflow control and distribution in HVAC and cleanroom setups. We offer various sizes and designs to match your project needs.
What filter modules and HEPA filter options are available for AHUs?
We manufacture mini pleat HEPA filters, gel seal HEPA filters, V-bank filters, and deep pleat HEPA filters. These filter modules are ideal for AHUs in cleanrooms, hospitals, and industries needing ultra-clean air.
Do you offer modular solutions like operation theatres and cleanroom panels?
Yes. Our solutions include modular operation theatre installation, cleanroom wall and ceiling panels, and custom view panels, windows, and frames for observation areas.
Are Ultrafil AHUs suitable for hospitals, pharmaceutical companies, and labs?
Absolutely. Our AHUs, filters, dehumidifiers, and cleanroom accessories are widely used in hospitals, pharma plants, laboratories, manufacturing units, and R&D facilities throughout India.
How do I know if my AHU needs maintenance?
Warning signs include unusual noises, reduced airflow, higher energy bills, or visible dust buildup. Regular inspections help detect problems early and keep your AHU running efficiently.
How often should I maintain my AHU?
We recommend servicing your AHU every 6–12 months, depending on usage and environment. Maintenance should include cleaning or replacing filters, checking pressure drop across filters, cleaning coils and drain pans, and inspecting wiring and connections.
Can you provide custom AHUs?
Yes. We specialize in custom AHUs built to your exact specifications from size and airflow capacity to special filtration and control options. Just share your requirements, and we’ll design a tailored solution.
