Understanding Area Classification, Temperature & Humidity in Cleanroom Design

At SUN CleanAir Systems, Vasai, we specialize in designing and supplying cleanroom environments that meet the highest standards of cleanliness, safety, and regulatory compliance. Two critical aspects of cleanroom planning—area classification and environmental control (temperature and humidity)—are foundational for successful pharmaceutical, semiconductor, food, and biotech manufacturing operations.

What is Area Classification?

Area classification defines the cleanliness level of a room based on the concentration of airborne particles. It determines the environmental requirements and types of filtration and HVAC systems to be installed. In regulated industries like pharmaceuticals, area classification is based on ISO 14644-1 or GMP (Good Manufacturing Practice) guidelines.

Common Classifications Include:
  • ISO Class 5 / Grade A : For critical zones like filling or aseptic operations
  • ISO Class 6 - 7 / Grade B : Background for aseptic preparation and filling
  • ISO Class 8 / Grade C & D : Less critical operations like preparation and packing

Each class defines the maximum allowable particle count (per m³) at specified micron sizes.

Importance of Temperature & Humidity Control

Along with particle control, cleanrooms must maintain precise temperature and humidity levels to:

  • Prevent microbial growth
  • Maintain equipment functionality
  • Ensure product integrity
  • Improve employee comfort and safety
Typical Cleanroom Ranges :
  • Temperature : 21°C to 25°C (±1°C)
  • Relative Humidity : 45% to 60% RH (±5%)

However, the exact parameters vary depending on the product, process, and regulatory requirements.

How SUN CleanAir Systems Delivers Excellence

At SUN CleanAir Systems, we integrate high-performance HVAC systems with HEPA/ULPA filtration, dehumidification units, and BMS (Building Management Systems) to ensure continuous monitoring and control of:

  • Air changes per hour (ACH)
  • Positive/negative pressure differentials
  • Real-time temperature and humidity levels
  • Area zoning and validation

Our custom solutions ensure each cleanroom complies with ISO, WHO-GMP, USFDA, and EUGMP standards.

Applications We Serve:
  • Pharmaceutical Manufacturing
  • Biotechnology Research Labs
  • Microelectronics & Semiconductor Assembly
  • Hospitals & Operating Theatres
  • Food & Beverage Processing
