HVAC Fundamentals for Pharma | Airflow, Filtration, Pressure, Temperature & Humidity

Welcome to Section 2 of the HVAC Qualification Course by Pharmatalks. In this video, we cover the essential HVAC fundamentals every pharmaceutical, cleanroom, validation, and engineering professional should understand. Learn how an HVAC system controls airflow, temperature, relative humidity, filtration, pressure balance, and air distribution to support GMP-compliant cleanroom environments. Topics covered in this section: • Basic HVAC system operation • Air Handling Units (AHUs) and key components • Supply air and return air concepts • Airflow and air distribution • Pre-filters, fine filters, and HEPA filtration • Temperature and humidity control • Differential pressure and room pressure balance • Dampers, diffusers, grilles, fans, coils, and control systems • Why HVAC performance is critical for product quality and patient safety This section builds the foundation needed before moving into HVAC qualification activities such as DQ, IQ, OQ, PQ, airflow testing, HEPA integrity testing, and environmental monitoring.
