B\u1ea3n ti\u1ebfng Anh ho\u00e0n ch\u1ec9nh:<\/p>\n<p>Operating theatres are one of the most stringent air-quality-controlled environments in the healthcare sector. According to ISO 14644 and Ministry of Health guidelines in Vietnam, operating theatre air must meet at least ISO Class 5\u20137, with air change rates of 15\u201325 ACH and H13\/H14 HEPA filters.<\/p>\n<p>Before investing in an air filtration system, hospitals need to clearly determine:<\/p>\n<h3>1. Required Cleanroom Level (ISO Class)<\/h3>\n<ul>\n<li>Standard operating theatre: ISO Class 7 (10,000)<\/li>\n<li>Open-heart and organ transplant operating theatres: ISO Class 5\u20136 (100\u20131,000)<\/li>\n<li>ICU recovery room: ISO Class 7\u20138<\/li>\n<\/ul>\n<h3>2. Appropriate Filter Types<\/h3>\n<ul>\n<li>Primary filter (G4\/M5): captures coarse dust and protects the HEPA filter.<\/li>\n<li>Intermediate filter (F7\/F9): captures fine PM2.5 particles.<\/li>\n<li>HEPA filter (H13\/H14): efficiency \u226599.97% for 0.3 \u00b5m particles.<\/li>\n<\/ul>\n<h3>3. Air Distribution System<\/h3>\n<p>Ceiling-mounted HEPA Terminal Housing creates uniform airflow and helps eliminate microbial dead zones. Positive pressure (+10 Pa) prevents outside air from infiltrating the operating theatre, maintaining a stable sterile environment.<\/p>\n<p>Air Filtech has deployed air filtration systems in dozens of hospitals and clinics nationwide, including Hospital 175, Hospital 108, and provincial healthcare facilities. Each project is surveyed on-site and individually designed according to the specific requirements of each healthcare facility, then tested and accepted in accordance with ISO 14644-1 before handover and commissioning.<\/p>\n<ul>\n<li><strong>Hospital 175 (Ho Chi Minh City)<\/strong> \u2014 Upgraded operating theatre filtration to ISO Class 7 using H14 HEPA filters.<\/li>\n<li><strong>Hospital 108 (Hanoi)<\/strong> \u2014 Installed Terminal Housing and positive\/negative pressure control systems.<\/li>\n<li><strong>Binh Duong General Hospital<\/strong> \u2014 Designed air filtration systems for ICU areas and pharmaceutical compounding cleanrooms.<\/li>\n<\/ul>\n<p><strong>Contact Air Filtech today for a free consultation on an operating theatre air filtration solution tailored to your facility&#8217;s scale, technical requirements, and budget.<\/strong><\/p>\n<p><strong>Free Consultation:<\/strong><br \/>\nHotline: <a href=\"tel:0899944666\">08 999 44 666<\/a><br \/>\nEmail: <a href=\"mailto:info@airfiltech.vn\">info@airfiltech.vn<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Going green and reducing your carbon footprint are important steps towards creating a more sustainable future for our planet.
