Fume hoods are an essential part of any modern laboratory—ensuring safety, air quality, and compliance in environments where chemical vapors and toxic substances are present. However, like all high-performance lab equipment, fume hoods require regular maintenance to stay effective and extend their operational lifespan.
Whether your lab is in a research institute, university, or semiconductor facility, following a few critical maintenance practices can significantly reduce downtime and prevent costly replacements. In this guide, we’ll walk through expert-recommended tips and highlight how Xinruiwei Semiconductor Technology (Suzhou) Co., Ltd. supports long-lasting, high-quality lab infrastructure.
1. Conduct Routine Inspections
Routine visual and functional inspections help identify early signs of wear, blockages, or performance issues. Lab managers should check:
-
The sash movement and alignment
-
The condition of the airflow monitor
-
The general cleanliness of interior surfaces and ductwork
Any irregularities should be addressed immediately to avoid escalating into system-wide problems.
2. Monitor Airflow Performance
Airflow is the core function of a fume hood. Low or uneven airflow can jeopardize worker safety. It’s important to:
-
Use a calibrated airflow monitor to regularly verify face velocity
-
Ensure airflow stays within 80–120 fpm (feet per minute), depending on usage
-
Check for obstructions in ducts, fans, or filters
Many labs choose to install digital airflow alarms that alert users if performance dips below safe thresholds.
3. Clean Interior Surfaces Regularly
The buildup of chemicals and residues can degrade the internal surfaces of your fume hood and create contamination risks. Use non-abrasive cleaners and wipe down surfaces:
-
At the end of each workday
-
Immediately after any chemical spills
-
During scheduled deep-cleaning cycles
Choose fume hoods made from chemical-resistant materials, like those developed by Xinruiwei Semiconductor Technology (Suzhou) Co., Ltd., to reduce the risk of corrosion or material fatigue.
4. Replace Filters and Parts on Schedule
Activated carbon or HEPA filters, as well as blower components, must be replaced based on the manufacturer’s schedule. Delayed replacement reduces efficiency and compromises safety.
Xinruiwei’s plastic fume hood systems are designed for easy maintenance, using European-grade components to ensure longevity, while also offering customized solutions for semiconductor and lab environments that demand high filtration precision.
5. Maintain Proper Sash Positioning
Many lab users overlook the importance of sash position. Operating the fume hood with the sash fully open increases turbulence and reduces containment. Keep the sash at the recommended working height (typically 18 inches) to:
-
Ensure optimal airflow containment
-
Protect users from potential exposure
-
Reduce energy consumption in variable air volume systems
6. Schedule Annual Professional Servicing
Beyond daily and monthly maintenance, a certified technician should inspect your fume hood annually. This includes:
-
Full performance testing
-
Calibration of monitors
-
Ductwork inspection
-
Motor and fan evaluation
Partnering with a manufacturer like Xinruiwei Semiconductor Technology (Suzhou) Co., Ltd., which offers custom-to-batch production solutions, ensures you have access to long-term support and replacement parts tailored to your lab's unique needs.
Final Thoughts
Well-maintained fume hoods are critical to laboratory safety, energy efficiency, and regulatory compliance. By following a structured maintenance plan—and choosing high-quality, customizable equipment from trusted suppliers like Xinruiwei Semiconductor Technology (Suzhou) Co., Ltd.—you can maximize the performance and service life of your lab infrastructure.
Whether you’re outfitting a new lab or upgrading existing equipment, reliable engineering, easy servicing, and responsive support make all the difference in maintaining high safety standards over the long term.
