Guide Specifications
1.0 General
1.1 Molecular contamination control filters shall be
Flanders High Mass and Zero Dust (HMZD) bond-
ed carbonpanels. Panels shall be self-supported
bonded granular carbon and be sized to fit into the
selected Flanders Pureseal front or side access
housing as well as competitive carbon systems.
Model numbers shall be as per schedule for appli-
cation specific requirements.
2.0 References
2.1 ASTM test method D 3467-88, Standard Method
for Carbon Tetrachloride Activated, American
Society for Testing and Materials, Philadelphia,
1988.
3.0 Construction
3.1 The granular carbon shall be bonded together in
a briquette form so that the panel contains no
loose carbon; loose filled tray type systems are
not permitted.
3.2 Panels shall be covered on both sides with a
white spun bonded polyester scrim and framed in
a galvanized (or stainless steel) channel; plastic
frames are not permitted. A black poly-butyl (or
silicone) gasket shall be affixed to one side of the
panel frame for front access designs.
3.3 The bonded carbon configuration shall not settle,
shall not particulate and shall not allow channeling
through the bed.
3.4 The bonded panels shall be self-supporting and
when installed in the housing shall provide a con-
tinuous seal around its periphery.
4.0 Packaging
4.1 The panels shall be individually sealed into a
polyethylene bag prior to being boxed. Filters
shall be stacked on pallets and stretch wrapped.
5.0 Carbon Material
5.1 The panels shall be composed of virgin coconut
shell granular activated carbon with a m i n i m u m
carbon tetrachloride (CTC) activity of 60% per
ASTM D-3437. The granular carbon shall be 4x8
US mesh size with an apparent density of 0.49
g/ml minimum. The minimum hardness shall be
97 per ASTM D 3802. The minimum surface area
shall be 1100 m2/g (N2BET Method) and the
moisture content shall not exceed 5%.
5.2 The carbon shall be Flanders Tech Sorb TS (car-
bon type model number) as designed for the
removal of (contaminant). The contaminant
removal capacity shall be (x%) by weight as (chal-
lenge).
