The difference between an air handling unit and a package unit have to do with the way air is circulated or cooled. An air handling unit recycles the air from the structure back into the system. A package unit cools the air as it enters a structure through the use of intake fans.
air handling units reserculate the treated air at required temperature at any serving area but fresh air unit did not reserculate fresh air , exhaust used air.

The term cfm stands for cubic feet per minute. It is a unit of measurement used to determine the amount of air flow,.
If you are talking about the forced air furnace that is in the basement or attic you would need to find the amount of air flow from your air handler (CFM) For every 400 CFM you would need about 1 ton of cooling or 12000 BTU For instance my air handler is 1200 CFM therefore i could handle 3 tons easily. This is a rule of thumb but remember that if your air filter is dirty your air flow will be decreased and could cause possible freezing of the cooling coil or evaporator coil.
The operating principle of air handling unit is by circulating and then conditioning air flow. This is achieved by cooling, heating and ventilating the units.

Yes. The blower motor of an air handling unit can be considered as an ignition source.
Check the air flow per cubic meter of your diffuser area cover in your unit. CFM= cubic feet per minutes.
