The Critical Importance of Pharma HVAC
In the pharmaceutical manufacturing sector, indoor climate control is not just about human comfort; it is a critical component of product quality, safety, and regulatory compliance. Contaminants, moisture, and temperature fluctuations can ruin raw materials and compromise life-saving medicines. This makes robust, specialized HVAC systems essential for cleanroom environments.
Meeting WHO GMP and ISO Cleanroom Standards
Pharmaceutical cleanrooms in Bangladesh must meet strict World Health Organization (WHO) Good Manufacturing Practices (GMP) and ISO classifications. These guidelines regulate:
- Air Filtration: The use of advanced HEPA filters to capture 99.97% of airborne micro-particles down to 0.3 microns.
- Differential Pressure: Maintaining higher pressure in clean zones to prevent untreated air from rushing in when doors are opened.
- Humidity Control: Exact relative humidity (RH) control (typically between 35% and 50%) to prevent powder clumping and microbial growth.
- Air Change Rates: High rates of clean air circulation (from 20 to over 60 air changes per hour depending on class) to dilute contaminants.
As an expert cleanroom contractor in Bangladesh, The Aircons Ltd. designs and installs custom pharma HVAC infrastructure, combining high-grade AHUs, CMS brand HEPA filters, precise humidity controls, and positive pressure ducting systems.
