What to do if there is no air circulation in Germfree BBF 4 Laboratory Equipment?
If there's no air circulation, check the motor blower control. Also, inspect the circuit breaker on the control panel. Finally, using the electrical diagram, check the wiring connections.
What to do if the Germfree Laboratory Equipment air supply is inoperative?
If the air supply is inoperative, first, check the main switch to ensure it is on. Make sure the plug is properly inserted into the electrical outlet and that the green light switch is illuminated.
What causes exhaust air imbalance in Germfree BBF 4 Laboratory Equipment and how to fix it?
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.
Why is the air velocity low in my Germfree BBF 4 Laboratory Equipment?
Low air velocity could be due to an obstruction in the plenum. Remove any obstruction. Other possible causes include low voltage on house current, loaded filters, improper adjustment of the blower motor, or a leak between the blower and plenum.
What causes high velocity air in Germfree BBF 4?
High air velocity can be caused by an exhaust air outlet obstruction. Remove the obstruction. Other possible causes include exhaust filter rupture, supply filter rupture, supply filter gasket leak or improper adjustment of blower motor speed control.
How to fix excessive blower vibration in Germfree BBF 4?
Excessive blower vibration is often caused by foreign matter in the blower squirrel cage. Remove any paper, paper clips, or other debris.
What to do if there is non-laminar airflow in Germfree BBF 4 Laboratory Equipment?
Non-laminar airflow can be caused by a large object obstructing airflow. Remove the item.
What to do if my Germfree BBF 4 has exhaust air imbalance?
If your Germfree Laboratory Equipment has an exhaust air imbalance, it may be due to several reasons. Check for any obstruction over the exhaust filter, and remove it if present. Ensure the blower motor control is properly adjusted by checking the Magnehelic gauge. Also, inspect the plenum for any obstructions and remove them. Note that if there is a leak between the blower and plenum or the filter is loaded, you should contact a certification company to repair the leak or replace the filters.
What to do if my Germfree BBF 4 has low velocity air?
If the Germfree Laboratory Equipment exhibits low air velocity, there might be several reasons. Check for any obstruction in the plenum and remove it. Note that if there is low voltage on house current, the filter is loaded, there is an improper adjustment of the blower motor, or a leak between the blower and plenum, you should contact a certification company to measure voltage, replace filters, adjust to proper reading on Magnehelic gauge or repair leak.
Why is there no air circulation in my Germfree BBF 4 Laboratory Equipment?
If there is no air circulation in your Germfree Laboratory Equipment, it could be due to the blower being off. Check the motor blower control. It could also be due to a blown circuit breaker. Check the circuit breaker on the control panel.
