    What causes exhaust air imbalance in Germfree Laboratory Equipment and how to fix it?
    • M
      Manuel NicholsAug 14, 2025
      Exhaust air imbalance can be caused by several factors. First, check for any obstruction over the exhaust filter and remove it. Second, make sure that the blower motor control is properly adjusted to the correct reading on the Magnehelic gauge. Third, check for and remove any obstruction of the plenum. If these steps do not solve the problem, there may be a leak between the blower and plenum, or the filters may need to be replaced.
