Introduction to Fire Protection Enclosure Air Leakage Testing
Blower doors are large calibrated fans that were developed in the 1970s to test the air leakage of houses for energy conservation work, but the recognition of the stratospheric ozone problem in the 1980s led to a new application of this airtightness testing technology. Halon 1301, a gaseous fire protection agent, was found to have one of the highest ozone depletion potentials, and a significant source of halon discharge into the environment was found to come from the testing of halon total flooding fire protection systems. In a typical application, such as a computer room, the acceptance test for the system involved a "discharge test" where the fire protection system was triggered, a full load of halon was discharged into the room, and the residence time for the halon in the room was measured. When the ozone depleting potential of these acceptance tests was discovered, there was a need for a new type of acceptance test that did not involve the discharge of halon 1301 into the atmosphere.
Infiltec's experience in air leakage test equipment development enabled it to invent a test that solved this problem. The "enclosure integrity test" involves measuring the total area of the holes in the protected room with a blower door, assuming a worst-case distribution of leaks across the enclosure surface, and computing the worst-case leakage of the fire protection gas mixture through those holes. David Saum and Arthur Saum of Infiltec were issued US patent #5,128,881 Means and Methods for Predicting Hold Time in Enclosures Equipped with a Total Flooding Fire Protection Fire Extinguishing System for this work. This test was incorporated into the NFPA 12A Standard for halon 1301, and it has since been modified for halon alternative gases in the NFPA 2001 Standard.
Infiltec is a worldwide supplier of test equipment for the measurement of fire protection enclosure integrity, and it also provides consulting and training services worldwide.

Free Infiltec Software for Analyzing Halon Alternative Integrity Tests
DEMO PROGRAM SUMMARY
The free DOS program HA is a modified version of the program LA that was developed by Infiltec to analyze enclosure leakage analysis data for the halon alternative gases by the calculation procedure in the NFPA-2001 standard. The program LA can create, edit and save test data files, and it is available from Infiltec.
The HA program was designed to provide information on halon alternatives enclosure leakage testing and is distributed free of cost, as long as the program and its data files remain unchanged. If you would like to give the program to someone else, we recommend that you distribute the compressed file HALONALT.EXE which contains both the program and all its data files. Run HALONALT.EXE to extract the program HA and its data files.
HA is a DOS program that is designed to run on any PC in the DOS mode, or from WINDOWS as a DOS application. The print function in this program is set for LPT1, and the graphics will automatically adjust to your type of monitor. The program can either be run from a floppy disk or hard disk.
Infiltec Fire Software for NFPA-2001 Clean Agent Blower Data Analysis for 12 gases: Halon 1301, C02, FM-200, INERGEN, CEA-410, NAF-SIII, FE-13, Argonite, FIC-1311, Argon, FE-241, FE-25. Include pre-test prediction to estimate how many blower doors will be needed for test. (compatible with IBM type PC, on 3.5" disk or CD)

Infiltec Enclosure Integrity Test Instruments
Infiltec offers digital models for the highest accuracy measurements, and analog models that meet all current test standards:
The Infiltec dual digital E3-A-DM4 combines the latest in low pressure electronic sensors, embedded processor and digital display technology to produce the most accurate, easy-to-use Enclosure Integrity Test Instrument.
Digital E3-A-DM4 Features:
| MODEL | DESCRIPTION | PRICE |
|---|---|---|
| E3-A-DM4-110 | Infiltec Digital Blower Door includes a fiberglass fan, aluminum door panel with nylon cover and case, DM4 Micro-Manometer, controls, calibration certificate, manual & case. The DM4 Micro-Manometer features digital flow and pressure measurement, leakage area (ELA) measurement, and dual auto-zeroing sensors for simultaneous flow and measurements. The resolution is 0.1 Pa and 0.001" wc, the range is ±750 Pa and ±3" wc, and the pressure accuracy is 1% of reading or 1 digit. The DM4 is calibrated for use with the E3 blower door, the Infiltec DL1 duct leakage tester, and Pitot tubes. Flow, pressure, and leakage area can be displayed in US, metric, or mixed units. Electronics are 110VAC/60 Hz. Options include software, fan covers, and door expander kit. NEW FEATURE: digital display of building leakage area in square inches/centimeters at any test pressure. Specifications Picture | $2,495 |
| E3-A-DM4-220 | Same as E3-A-DM4-110, except for 220VAC/50 Hz electronics. | $2,595 |
For testing larger spaces, the Infiltec Model E3-3FAN-STACK generates higher air flows by stacking up to 3 E3 fans in each door jamb.

Calibration and Repair.
Infiltec offers factory recalibration and repair for Infiltec instruments, and most other manufacturer's equipment. Note that recalibration requires that both the fan and the gauges be shipped to the Infiltec factory. If necessary, we can generally arrange for one-day turnaround on your recalibration.
