Welcome to XPT Tools and Equipment

Determine which XPT Duct Leakage Tester will fit your testing requirements.
Provide the Required Static Pressure and Maximum Allowable Leakage Values below. Click on the "Calculate Required Tester" button to determine which size tester is required for your application.
Test Pressure:	inches w.c.

Max Leakage:	CFM

Result:
Result does not include system losses. Additional losses can be included to required static pressure above.

Determine the capabilities of each Duct Leakage Tester can measure.
Select one of XPT Duct Leakage Testers. Next, select the required duct system test pressure. Finally, select the length of flex duct and number of bends that best match your duct system test setup.(Note: standard length duct flex included with each tester is 10 ft.) Click on the "Calculate Maximum Leakage Value" button to determine the CFM of your selected duct tester can measure.

Select Tester:

Test Pressure:	inches w.c.

Flexduct Length:	feet

Number Bends:	bends

Maximum Leakage(CFM) selected duct tester can measure:

Note: Calculations will vary dependant on equipment conditions and fan capabilities. Decreasing the number of turns, elbows, and flex duct length, increases the testing capacity of your tester.


Determine your allowable leakage based upon your duct leakage test class.
Provide the total area of your duct system to test. Select the correct duct leakage test class and required test pressure values. Click on the Calculate Maximum Allowable Leakage button to determine the required CFM measurement value calculated from your input data.
Duct System Area:	square ft.

Leakage Class:	class

Test Pressure:	inches w.c.
