Case: High-End Medical Laboratory – Ensuring Clean Vacuum System Emissions and Compliant Operation

Customer Background:
"Biorui Medical Laboratory" is a high-end facility specializing in precise biochemical analysis and gene sequencing. The lab is equipped with multiple Edwards E2M18 rotary vane vacuum pumps for sample preparation and processing. These pumps are critical for the efficient operation of core equipment, but the oil mist emitted during their operation had become a significant issue.

Pain Points:

Health and Safety Risks: Vacuum pumps directly exhausted oil-laden air into the laboratory. This not only caused an pervasive oil odor but also posed a potential threat to the respiratory health of researchers, seriously violating laboratory safety management standards (like COSHH) and indoor air quality requirements.

Equipment Contamination and Interference: Escaping fine oil mist settled on surfaces of adjacent precision instruments (e.g., mass spectrometers, optical equipment), potentially causing contamination, performance degradation, or failures, significantly increasing maintenance costs and risks.

Compliance Pressure: The laboratory faced increasingly strict environmental and occupational health and safety regulations. Failure to effectively manage oil mist emissions became a major compliance flaw, potentially even affecting operational permits.

Solution:
Installed the Edwards EMF20 Oil Mist Filter (Model: A462-29-000) on the exhaust ports of all E2M18 vacuum pumps. Its KF25 (NW25) ports allowed for quick and无损 installation, establishing a standardized oil mist management solution.

Results:

Dramatically Improved Environment: The EMF20 filter's 99.999% DOP test efficiency virtually eliminated visible oil mist and oil vapor emissions. The laboratory air became fresh,彻底 resolving the issues of oil mist pollution and odor, and providing a healthy and safe working environment for staff.

Equipment Protection and Cost Reduction: Adjacent precision instruments were protected from oil contamination, leading to reduced failure rates and extended maintenance intervals, indirectly saving significant equipment maintenance costs.

Worry-Free Compliance: Emission levels fully met and even exceeded the strict requirements of health and safety regulations like COSHH, easily passing various audits and eliminating operational permit risks. The semi-transparent lower section allows easy visual monitoring of the oil level, prompting timely replacement of the filter element (Consumable P/N: A223-04-199), ensuring continuous and effective filtration performance.

Safety and Reliability: The integrated pressure relief valve automatically opens if the filter element becomes blocked, preventing potential damage to the vacuum pump from excessive backpressure, ensuring system safety.

Customer Testimonial:
“The EMF20 filter might be a small component, but it's a 'major contributor' to our lab's sustainable operation. It acts like a silent guardian, completely solving the persistent oil mist problem that plagued us, allowing our lab environment to truly meet the high standards of cleanliness, safety, and compliance. Now, both our staff and our precision instruments can 'breathe freely'.”
