Air Handling & HVAC

What is ACPH? Air Changes Per Hour (ACPH) is a critical metric used to quantify the rate at which the entire volume of air within a specific space or room is exchanged or replaced with fresh, clean, filtered air in one hour. For instance, an ACPH value of ’40’ means that the entire air volume…

HVAC (heating, ventilation, and air conditioning) systems play a critical role in maintaining proper conditions within a cleanroom. The design of the HVAC system is a crucial factor in ensuring that the cleanroom meets necessary standards for cleanliness, temperature, humidity, and pressure. HVAC Systems in the Cleanroom The key components of an HVAC system for…

Passbox and airlock are two types of controlled environments used in various industries to prevent contamination during material transfer between different areas. While they serve similar purposes, there are some key differences between the two. Passboxes and airlocks are primarily distinguished by their sizes and use in clean room applications. Airlocks are bigger and are…

Cleanroom pressurization refers to the control of air pressure within a cleanroom environment to maintain desired cleanliness levels and prevent contamination. Cleanrooms have become critical for industries across various industries, including pharmaceuticals, medical, food processing, semiconductors, aerospace, and more. Cleanroom technology ensures high-quality production by keeping environmental parameters like temperature, humidity, and pressure under control while…

Ante Rooms Are So Important in GMP Facilities Airlock systems play an important role in pharmaceutical industries, protecting clean rooms from contaminants, and preventing cross-contamination. As the name indicates, airlocks refer to locking systems utilizing air pressure as a primary mechanism, as a means of protection in cleanrooms against contaminants during human and material movement.…

One of the main things that makes a cleanroom “clean”, is the air distribution & filtration system. The Pharmaceutical, Medical, Hospital and Food industries all share a similarity in that they require cleanrooms to properly operate to maintain their hygiene levels. A cleanroom is an enclosed space or area where the environment is controlled to…

Any controlled environment or cleanroom is expected to maintain a contamination-free, conditioned, and consistent air flow. Maintaining consistent cleanroom airflow is essential to keeping these spaces compliant with industry standards towards their intended research or manufacturing ends. There are multiple components to effective cleanroom strategy, but properly implementing and using an air filter system is one of the…

Basic HVAC System Principles Heating, Ventilation, and Air Conditioning (HVAC) systems are the heart of any building, working to regulate temperatures, humidity levels, and air quality in homes, commercial buildings, and industrial facilities. An efficient HVAC system is critical for maintaining cleanroom environments, where maintaining clean air is essential to the success of the operations.…
