FH-Series Airflow Sensors Help Assure CGMP Compliance 21 CFR 113 of the Electronic Code of Federal Regulations (eCFR) defines aseptic processing and packaging as “the filling of a commercially sterilized cooled product into pre-sterilized containers, followed by aseptic hermetical sealing, with a pre-sterilized closure, in an atmosphere free of microorganisms.” Environmental monitoring and control is essential […]

HEPA Filter Leakage Testing, Airflow Distribution Testing
Posted By: Jan Fischer

HEPA (high efficiency particulate air filters) filters and HEPA filter integrity are critical to air filtration systems in industries including pharmaceutical, semiconductor, food, and nuclear. HEPA filters are most effective when used at their rated airflow resistance and face velocity, and various standards have been implemented for certification and in-situ qualification testing of HEPA filters.

airflow monitoring for cleaner air
Posted By: Alex Sargent

The covid-19 pandemic has generated an increased interest in airflow and cleaning the air. Air cleaners, also referred to as air purifiers or sanitizers, use differing technologies including HEPA filtration, activated carbon filtration, ultraviolet (UV) germicidal irradiation, or multiple technologies such as filtration with UV disinfection. The ASHRAE Position Document on Filtration and Air Cleaning provides information on these […]

Airflow is Essential for Critical Containment Engineering controls are used to protect laboratory workers. Examples include exposure control devices (ECDs) such as chemical fume hoods and biosafety cabinets (BSCs), which are ventilated to contain harmful toxins and odors, and safeguard against fume releases into the room. These critical containment cabinets differ in design, and airflow […]

sidewall air velocity sensing for critical containment

Performance & Reliability with Sidewall Air Velocity Sensing Lab managers often choose to use sidewall sensors to maintain the face velocity of fume hoods and biosafety cabinets, instead of duct-mounted probe-style sensors, in applications where the exhaust flow is dirty or extremely hot. The long term exposure of probe-style sensors to depositing particulates or corrosive chemicals may compromise […]

AMC Filtration for Contamination Control Airborne molecular contamination (AMC), or chemical contamination, is the presence of gases or vapors in the atmosphere that may have a detrimental effect on process, equipment, and product in cleanrooms and controlled environments. AMC is a concern for the semiconductor industry, wafer fabrication, hard drive manufacturing, and other high technology […]

infection prevention with airflow monitoring
Posted By: John Callanan

Infection prevention and control (IPC) measures to protect personnel, patients and visitors are well-established by laboratories, clean rooms and multitudes of other public and private entities. In light of the COVID-19 pandemic and ASHRAE COVID-19 guidance, many are upgrading engineering controls for their facilities and refining strategies to remove hazards through air ventilation.   Environmental Health and […]

Hospitals and health care facilities recognize the importance of protecting patients, workers, and patrons from hazards. They evaluate their ventilation systems on an ongoing basis, and work continuously to make systems and engineering controls better for improved health and safety.  Healthcare organizations are installing room-based pressure monitors in all types of functional areas to further […]

Embedded Sensing Provides Benefits High performance electronics are increasingly being developed with built-in air velocity sensing to improve reliability, warn the user of a use-case or environmental issues, and to allow the OEM to track airflow starvation events that could mitigate product failure liabilities. DegreeC has developed cost effective and small form factor approaches to […]

HEPA Filtration Helps Prevent Airborne Transmission of Infectious Diseases A HEPA filter, high-efficiency particulate air filter, is used to describe a filter that exhibits a minimum efficiency of 99.97% at a test aerosol diameter of 0.3 micrometers, assuring a high level of protection against the transmission of airborne diseases. HEPA filtration is widely applied in laboratory, […]
