NOTE: Any listed and labeled factory-built commercial exhaust hood tested in accordance with UL Standard 710 by a nationally recognized testing laboratory, should be installed according to the terms of its listing and the manufacturer's installation instructions.

RATE OF EXHAUST FLOW CALCULATIONS

Based on the 1996 International Mechanical Code.

The Rate of air flow required for a vent hood is calculated using the following definitions:

Q= Rate of Air Flow in Cubic Feet Per Minute or [ CFM ] Required for the Hood.

A = Area of Hood Opening in Feet2 = (L x W)

D= Clearance Height = Distance in Feet from lower lip of hood to top of dishwasher chamber.

P = Perimeter of Hood that is Open. This depends on the hood design, as follows:

P =

If there are four open sides (Island Design), the calculation of the Rate is as follows:

Q = 75 x A

If there are three or fewer open sides, the calculation of the Rate is as follows:

Q = 50 x A

As an alternate method, the Rate can be calculated as follows:

Q = 50 x P x D

Example:

L = 3

W = 3

D = 2
