What does a cleanroom electrical system include?
Cleanroom electrical systems do more than supply equipment with power: they must support safe, stable operation and the cleanroom's operating requirements. Power distribution Provides…

What does cleanroom maintenance involve?
Cleanroom maintenance involves inspecting, cleaning, adjusting and replacing equipment to maintain cleanliness, temperature, humidity, pressure differentials and air quality as required. Inspect the HVAC…

Common cleanroom classifications
Cleanrooms are classified by the level of airborne particle control. ISO 14644-1 classification is based on airborne particle concentration. The required class depends on…

Cleanroom HVAC testing and commissioning process
T&C (Testing & Commissioning) is the process of inspecting, testing, measuring and adjusting HVAC before the cleanroom enters service. Its aim is to verify…

What is TAB, and why is air balancing necessary?
In a cleanroom HVAC system, correct design and complete installation alone do not guarantee effective operation. TAB (Testing, Adjusting & Balancing) is the process…

Selecting panels for pharmaceutical factories
GMP is a target for many pharmaceutical businesses. Achieving it requires expertise from the earliest stages of factory construction. Panels are a common cleanroom…

Cleanroom design and construction process
Cleanroom design and construction involves more than building an enclosed room. It combines architecture, HVAC, air filtration and environmental control to achieve the required…

What is a cleanroom HVAC system?
cleanroom HVAC system is a Heating – Ventilation – Air Conditioning system designed to control a cleanroom's environmental conditions, particularly air cleanliness, temperature, humidity,…

Temperature and humidity control in cleanrooms
Temperature and humidity limits depend on products, processes and personnel. There is no universal temperature–humidity pair for every cleanroom. Specify permitted ranges, operating modes…

HEPA filters: what should operators check?
HEPA filters capture airborne particles. Filter efficiency and the integrity of the installed assembly are different issues. Leaks may occur through media, frames or…

Cleanroom handover: the essential checks
Completed construction does not establish readiness for use. Confirm performance against agreed requirements. ISO 14644-1 classifies airborne particle cleanliness. ISO 14644-3 provides test methods.…

Cleanroom pressure differentials and airflow direction
Pressure differentials help direct air between areas. Evaluate actual airflow paths alongside pressure readings. Product protection commonly directs air from cleaner to less-clean areas.…
