Air Filtration for Your Needs

Food Grade Compliant Filters

Whenever filter elements and filter housings are used in the Food and Beverage industry, they become subject to specific regulations regarding the selection of materials allowed. The principle underlying these regulations ((EC) No 1935/2004 for Europe and CFR Title 21 for Americas) is that any material or article intended to come into contact directly or indirectly with food must be sufficiently inert to preclude substances from being transferred to food. All our process filter elements and housings have been tested by independent and accredited third parties to comply with both the CFR Title 21 and the (EC) No 1935/2004 and all subsequent amendments. 

Sterile Grade Filtration

For highly sensitive applications where the compressed air is in direct contact with the product itself or aseptic packaging materials it is recommended to utilize final filters that are clearly marked as “sterile grade” (VDMA 15390-2:2018-04). According to the FDA* a sterile grade filter element is required to retain 10⁷ organisms per cm² of filter surface. Our filter elements PFs+ and MFs+ fulfil this requirement as shown in an Aerosol Bacterial Challenge Test using Brevundimonas diminuta as experimental microorganism. The retention efficiency for both PFs+ and MFs+ filter element types is higher than 99,99999% or LRV > 7/cm². 

Class 0 Particle Filtration

When working with the most demanding applications like electronics and battery we recommend using absolute Class 0 filtration for which we need to step up the technology ladder. The MFs+ range relies on a PTFE membrane assimilated in a propylene structure to stop practically all particles of relevant size – guaranteeing the highest air quality.
