Mott High Purity
All Metal Multitube Gas Filters
All-Metal Filters Ideal
for Oxygen Service
Process engineers in the biotech
industry are increasingly turning
to enrichment techniques to
increase oxygen mass transfer
and maximize cell growth.
Oxygen enrichment techniques
in bioreactor systems can lead
to safety challenges because
elevated levels of oxygen in
bioreactor airflows can increase
the risk of spontaneous ignition
of conventional air sterilizing filter
materials like PTFE. Based on studies by an independent
gas association, the use of filters with nickel elements
greatly reduces the safety hazards associated with
adiabatic pressure release and spontaneous ignition
of oxygen systems. Mott Corporation’s High Purity
Segment is the first to offer a gas filter cartridge utilizing
this robust and effective media.
The filter membrane is constructed of Nickel 200 material,
a widely used material that is the least likely to ignite in the
presence of elevated or pure oxygen levels. The 316LSS
adapter and end-cap materials minimize combustibility
compared to PTFE or polypropylene, a common material
of construction in other gas filters.
The Mott Nickel porous filter media was evaluated by
the European Industrial Gas Associations (EIGA) and
found to be the least likely material to ignite in the
presence of pure oxygen or enhanced oxygen levels.
Mott High Purity all-metal filter cartridges are designed to
remove particles and biomass from air and gas streams.
Made with Mott Penta® Nickel media and 316LSS
hardware, these filter cartridges provide filtration levels
down to 0.003µm in gases. They include standard
226 double o-ring style adapters for easy retrofit into
existing filter housings.

Other Metal Filter Membranes Available
Mott metal filter cartridges are available in all 316LSS,
Hastelloy® C-22, Monel® and Nickel 200. Mott High
Purity all-metal filter cartridges are designed developed
and manufactured in accordance with ISO-9001 quality
systems standards.
Each part is marked with part numbers and lot
identification for traceability and easy identification.
