FLOW
RATE,
(approx).
CHARACTERISTICS
TFA41
4”
(10.16 cm)
Diameter
15-20 cfm
.4-.6 cmm
Ashless paper. 95% collection efficiency of 1
micron. 58% DOP on 0.3 micron particles.
Easily countable for Alpha particles,
obtaining 70% count and a penetration
absorbtion of approximately 30%. Good
efficiency for industrial dusts and for
particulate matter size 1 0 microns and
under to submicron to .01 micron. Sampler
may be operated for approximately 1 hour
without overheating. Dissolvable with
dimethylphthlate
TFAGF41
Glass Fiber
4" Diameter
15-20 cfm
.4-.6 cmm
Binderless. Very high retention of fine
particles. 99.98% retention efficiency of 0.3
micron particles. Recommended wherever
gravimetric weighing ananlysis is used
because of non-hydroscopic properties.
Sampler may be operated for approximately
1 hour without overheating. Also see data on
Glass Fiber Filters below.
TFA69
6" x 9"
50-58 cfm
1.4-1.7
cmm
Same specs as TFA41, except Sampler may
be operated for approximately 24-48 hours.
TFAGF69
Glass Fiber
6" x 9"
50-58 cfm

TFA810
8" x 10"
60-70 cfm
1.7-2 cmm
Same specs as TFA69.
TFAGF810
Glass Fiber
8" x 10"
60-68 cfm
1.7-2 cmm
Same specs as above. Also see data on
Glass Fiber Filters below.
TFA2133
4"
Diameter
36-40 cfm
1.0-1.1
cmm
Moderate flow rate. Moderate resistance
buildup. 95% Collection Efficiency of
particles 0.5 microns and over. Countable
for Beta Radiation. Sampler may be
operated for one hour or more depending
upon saturation without significantly
overheating.
TFAQ810
Quartz
Fiber
8" x 10"
60-68 cfm
1.7-2 cmm
Pure quartz. Binderless. 99.9% retention
efficiency of 0.3 micron particles.
Recommended for PM10 and PM2.5 High
Volume Air Sampling.
