As per your demand here I am providing you information about the CFM of the Brinco Mechanical Management Services, Inc.


Most packaged of air conditioning equipment is designed for, and rated at, 400 CFM per ton.

Typically, a 7.5 ton unit will be selected with a drive package that causes it to deliver 3,000 CFM against whatever resistance the ductwork and grilles offer.

For example, the unit might be specified to deliver 3,000 CFM at 0.8 of an inch of static pressure.

While packaged equipment is designed at the 400 CFM per ton norm, most units are capable of operating at air volumes between 325 CFM per ton and 500 CFM per ton.

As we increase the air quantity on a particular unit, three things happen:

The total capacity the unit delivers increases.
The sensible capacity of the unit increases.
The latent capacity of the unit decreases.

For our purposes, latent capacity is the ability of the unit to lower the humidity or to remove moisture from the air and sensible capacity is the ability of a unit to lower the air temperature.

For a 10 ton packaged rooftop unit operating at standard conditions, consider the following:


Supply Air Quality Total Capacity Sensible Capacity Latent Capacity
3000 CFM 116 MBH 79 MBH 37 MBH
4000 CFM 123 MBH 90 MBH 33 MBH
5000 CFM 126 MBH 99 MBH 27 MBH
