It is commonly used for treating outdoor air before supplying it to occupied or process spaces.<\/p>\n<h3>What is the difference between AHU and FAHU?<\/h3>\n<p>An AHU can handle return air, mixed air and\/or outdoor air depending on the design. A FAHU is primarily designed to handle and condition outdoor fresh air.<\/p>\n<h3>Does a Fresh Air AHU cool air?<\/h3>\n<p>Yes. Where cooling is required, a Fresh Air AHU can use a chilled-water or DX cooling coil to condition outdoor air.<\/p>\n<h3>Does a Fresh Air AHU require filters?<\/h3>\n<p>Yes. Filtration is an important part of fresh-air treatment. The number and type of filters depend on outdoor-air quality and application requirements.<\/p>\n<h3>Can HEPA filters be used in a Fresh Air AHU?<\/h3>\n<p>Yes, HEPA filtration can be incorporated where the application requires high-efficiency particulate filtration. The complete filtration design should be based on the project&#8217;s requirements.<\/p>\n<h3>Can Fresh Air AHU control humidity?<\/h3>\n<p>It can be designed to help control humidity through cooling\/dehumidification and, where required, humidification or other humidity-control methods.<\/p>\n<h3>Where are Fresh Air AHUs used?<\/h3>\n<p>They can be used in offices, hospitals, pharmaceutical facilities, cleanrooms, hotels, manufacturing plants, textile industries, food-processing facilities and other commercial or industrial buildings.<\/p>\n<h3>Can Fresh Air AHU be connected to a chiller?<\/h3>\n<p>Yes. A chilled-water Fresh Air AHU can be connected to a central chiller plant.<\/p>\n<h3>Does VIPUL HVAC provide Fresh Air AHU installation?<\/h3>\n<p>Yes. VIPUL HVAC provides AHU-related design, supply, installation, testing, commissioning and maintenance support according to project requirements. <a href=\"https:\/\/vipulhvacsolution.in\/blog\/ahu-supplier-in-india\/\">Vipulhvac Solution<\/a><\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A <strong>Fresh Air AHU<\/strong> is much more than a fan and filter. It is an engineered HVAC system that can combine <strong>outdoor-air ventilation, filtration, cooling, heating, humidity control, air distribution and automation<\/strong>.<\/p>\n<p>The correct design should consider fresh-air quantity, cooling load, filtration, static pressure, indoor conditions, energy efficiency, ductwork and maintenance.<\/p>\n<p>For industrial, pharmaceutical, healthcare, commercial and institutional projects, choosing an experienced HVAC partner can help ensure that the Fresh Air AHU works as part of the complete ventilation and air-conditioning system.<\/p>\n<p><strong>VIPUL HVAC SOLUTION PVT.
