A Positive Pressure Module (PPM) is a specialized unit designed to maintain a higher internal pressure than the external environment, preventing the ingress of contaminants. Key components include air filtration systems, blowers, pressure sensors, and sealed enclosures. PPMs are used in industries like pharmaceuticals, biotechnology, healthcare, and semiconductor manufacturing. They ensure a controlled environment, ideal for sensitive processes or cleanrooms. Manufactured using precision engineering, advanced filtration technologies, and airtight seals, PPMs require tools for airflow calibration and pressure monitoring. Clients benefit from enhanced product safety, contamination prevention, and compliance with strict regulatory standards, improving operational efficiency.
