HEPA Filter Leak Test

Purpose

After installing the new HEPA filter, the HEPA filter should be leak checked.
This test is performed to determine the integrity of the HEPA filter, the filter
housing, and the filter mounting frames. Leak testing is to be done by a qualified
technician with calibrated equipment. Remove the top perforated exhaust cover by
using a Phillips screwdriver to unfasten the (2) screws used to secure (2) clips. See
Figure 6-1. The filter passes the leak test at .01% or better. Reference Leak
Testing and Photometer scanning from the Institute of Environmental Services
(IES-RP-CC001.3)

Apparatus

1. An aerosol photometer ATI model 2D, 2E, 2G or equivalent. Air

Techniques Hamilton Associates inc. 11403 Cron Ridge Dr. Owings Mills,
MD 21117

2. One aerosol generator of the Laskin nozzle(s) type. An aerosol of mineral

oil or suitable liquid shall be created by flowing air through it. The compressed
air supplied to the generator should be adjusted to a pressure of 10± 1 psig.
during operation. Air Techniques Inc. Model TDA-4A or equal. One nozzle at
10 psig is (67.5 cfm x 100ug/l)/(Vol. of air), For the 2' at 90 fpm or 130 cfm,
one nozzle @10 psig is 6,750/130 cfm = 52 ug/l. For the 3' at 90 fpm or 200
cfm, one nozzle @ 10 psig is 34 ug/l. For the 4' at 90 fpm or 265 cfm, one
nozzle at 10 psig is 26 ug/l. For the 5' at 90 fpm or 215 cfm, one nozzle at 10
psig is 31 ug/l. For the 6' at 90 fpm or 260 cfm, one nozzle at 10 psig is 26
ug/l. Note 5' and 6' use two filters.

3. Mineral oil (Catalog #1491400).
