Alpha 95
Bulletin PB1400-1106
95% DOP Filter
FOREMOST IN AIR FILTRATION
General
Standard Alpha 95 filters have 1.7 times the cfm
capacity of standardAlpha Cell 99.97% DOP HEPA
filters at the same clean pressure drop. They are
normally rated at 500 fpm so that filter banks with
95% DOP filters can be sized the same as
ASHRAE-rated filter banks.
Flanders Alpha 95 filters are designed for use in
HVAC applications requiring cleaner air than is
possible with ASHRAE rated filters, but where
HEPA filtered air is not required. The filters are
rated at 95% efficiency on 0.30 micrometer
particles by the DOP test method. The Alpha 95
is rated MERV 17 per ASHRAE Standard 52.2.
Typical applications for Alpha 95 include:
• Hospitals
Alpha 95 filters are identical in design and con-
struction to theAlpha Cell HEPA filters except that
the media is 95% efficient on 0.30 micrometer par-
ticles.
• Biomedical
• Pharmaceutical
• Biotechnology
Installation Considerations
• Genetic Research
• Universities
Alpha 95 filters should be installed in Flanders
leak tight Alpha HEPA frames or Surelock Side
Access HEPA Housings on the positive-pressure
side of the system fan to prevent air bypass.
Sureaire diffuser sections, air mixing baffles or
long transitions should be used if the bank is close
to the fan.
• Laboratories
• Food Processing
• Photo Processing
• Semiconductor Fabrication
• Industrial Processing Systems Product
Installation of Flanders ASHRAE efficiency
prefilters upstream of the fan is recommended to
ensure economical Alpha 95 filter life.

Frame: Alpha 95 filters are available in a variety of wood and metal frame materials such as particle board, plywood,
galvanized steel and stainless steel. Alpha 95 filters are also available in 24 gauge corrosion resistant steel in single or
double headers for installation in side access or plenum applications.
Seal: The standard gasket seal is 0.75” x 0.25” neoprene for installation on either the upstream, downstream or both
sides of the filter. The standard Fluid Seal is Flanders Blu-Jel® Seal which is a two-part silicone material suitable for
temperatures up to 390°F.
Faceguards: Faceguards are used to protect the filter media from mechanical damage. The typical faceguard material
is expanded aluminized steel. Galvanized 4 x 4 mesh welded wire and Type 304 stainless steel faceguards are also
available.
UL: Alpha 95 filters are either UL900 Class 1 or Class 2 listed depending on materials of construction.
Banks: Alpha Frames are designed forAlpha 95 filters in built-up filter banks. Each filter is secured in the frame with
four bolt-type fasteners that either compress the gasket or press the knife edge into the gel in the filter channel to
maintain a leak-tight seal. Surelock B or C-3 gasket seal and Surelock C-4 for Blu Jel HEPA Filter Housings are
recommended for side-access applications. The filters are sealed in place with either spring-loaded swing arm assem-
blies or a locking mechanism. The swing arm assemblies or locking mechanism either compress the gasket or press
the knife edge into the gel in the filter channel to maintain a leak-tight seal.
