After doing lots of reading on this forum about which filter type to use, there seems to be a split consensus about using pleated vs. fiberglass filters. As a typical homeowner, I'm looking for a filter that will simply protect my A/C and furnace with the lowest air impedance; there has been lots of debate on weather a standard fiberglass …

The quality of air will be improved as all the air going to the system will be -40ºF pressure dewpoint class. The system will be dry after the "run in" period. The electrical energy cost to dry the compressed air will be reduced by $26,000/year – for a total compressed air system annual electrical energy savings of $120,000/year.

Louvre pressure drop occurs when frictional forces, caused by the resistance to flow, act on air moving through a louvre. Increased louvre pressure drop can prevent equipment inside the ventilated area drawing sufficient air through the louvre, resulting in overheating, as the equipment has to work harder to draw the air through.

Building owners must monitor the flow through air duct grills to test how well their ventilation systems work. A pilot tube assembly, a device containing multiple probes, measures the static pressure drop between the grill's two sides. The air flow rate through the grill is proportional to this pressure and is related to the grill's size.

With fewer air molecules above, there is less pressure from the weight of the air above. Pressure varies from day to day at the Earth's surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where the air is warmed often have lower pressure because the warm air rises. These areas ...
