Mott High Purity All-Metal Multitube Gas Filters
All-Metal Filters Ideal for Oxygen ServiceProcess 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 becauseelevated levels of oxygen in bioreactor airflows can increase the risk of spontaneous ignitionof conventional air sterilizing filter materials like PTFE. Based on studies by an independentgas 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 thisrobust and effective media.
The filter membrane is constructed of Nickel 200 material, a widely used material that is theleast likely to ignite in the presence of elevated or pure oxygen levels. The 316L SS adapterand end-cap materials minimize combustibility compared to PTFE or polypropylene, a common material of construction in other gas filters.
The Mott Nickel porous filtermedia was evaluated by theEuropean Industrial Gas Associations (EIGA) andfound to be the least likelymaterial to ignite in the presence of pure oxygen orenhanced oxygen levels.
