Fans (Air Filtration Systems)#

In PyLabRobot, fans refer to air filtration units that condition air within or around the deck to protect the sample from contamination.

Their main purpose is to maintain a clean environment for experiments by ensuring consistent airflow and particle removal, reducing risks from dust, aerosols, and microorganisms. These systems are not primarily designed for operator safety; separate equipment like fume extractors or biosafety cabinets serves that role.

Common filter technologies include:

  • HEPA filters: Capture ≥99.97% of airborne particles ≥0.3 µm, widely used to keep samples clean.

  • ULPA filters: Capture even smaller particles for higher-level cleanroom requirements.

  • Activated carbon filters: Remove volatile organic compounds (VOCs) and chemical fumes.

  • Prefilters: Trap larger particles to extend the lifespan of HEPA/ULPA filters.
