• Robust stainless steel segmented filter elements
• Use of easy-to-exchange cost-effective filter membranes
• Long filter membranes lifetime − can be sterilized up to 150x 
• Reduced inventory and disposal costs

• Easy control of proper filter performance
• Easy detection of filter damages  

• Less waste due to replacement of just the filter membrane

HYGIENIC GASES
Many food and beverage manufacturers need hygienic gases to make sure that every gas that contacts the beverage is hygienic and free of contamination.

COMPRESSED AIR TREATMENT
Across many industries compressed air is used. To make sure this air is free of particles, water, oil, or microorganisms it is valuable to use Haffman's microfiltration solutions. Especially when this compressed air is in direct contact with Food & Beverage or medical applications.

WORT AERATION
An example is yeast fermentation. During the aeration of wort with oxygen to help the yeast cells to optimize the fermentation process a brewer should be certain to use clean air.

• PVF: Pre-filter(for removal of particles) 
• PSMF: Coalescence filter (for removal of water, oil and particles) 
• PAK: Activated Carbon Filter (for adsorption of oil vapors/hydrocarbons) 
• PSF: sterile filter (for removal of microorganisms) 
• PDF: Steam filter (for sterilization of sterile filter) 

FOOD-GRADE CO₂ TREATMENT
Another example is the dosing of food-grade CO₂. Across many industries such as breweries, soft drinks, and many others it is important to add CO₂ to carbonate products and make sure there are no oil vapor, particles, droplets, or oil in the gas.

• Stage 1: Coalescence filter, PSMF (for removal of water, oil, and particles)
• Stage 2: Activated Carbon Filter type PAK or PAKC (for adsorption of oil vapors/Hydro Carbons) 
• Stage 3: Activated Carbon Filter Sulfur Guard type PAKS (for adsorption of odors/H₂S, DMS, COS) 
• Stage 4: Pre-filter, type PVF (for removal of particles) 
• Stage 5: sterile filter, type PSF (for removal of microorganisms)

CULINARY STEAM
Also when using steam to sterilize or heat a process the steam needs to be hygienic. Therefore our filters retain 100% of the particles. The result: particle-free steam.

• Compressed Air Treatment
• CO₂ treatment for beverages and soft drinks

• Tank application: Yeast propagation
• In-line application: Wort aeration

Haffmans' Coalescence Filter CPM^® - PSMF is a validated submicron filter that removes particles, aerosols, and droplets of water and oil from the gas. It offers the most advanced pre-treatment of compressed air, CO₂, and other gases for food, beverage, biogas, and other industries. In combination with our activated carbon filter, type PAK, any residual oil vapor is further reduced. The coalescence filter is installed as a first-stage filtration followed by the activated carbon filter as a second stage filtration. Coalescing is the separation of liquid aerosols and droplets from gas. Using a coalescing filter element in a housing with three ports, the gas passes the filter element from the inside out. The inner layer is a high-efficiency coalescing layer and the outer layer is a coarser drainage layer. The fine liquid aerosols and droplets are captured by the fibers in the inner layer where they run together along the fibers to form larger drops. These drops are forced to the outside of the filter element and drain to the bottom of the housing by gravity. The condensate drain at the bottom of the filter element allows for easy removal of the captured liquid Solution to steam sterilization.

SOLUTION TO CLEAN STEAM FROM PARTICLES

Pre-filter
Haffmans' Pre-filter CPM^® - PVF is a validated pre-filter for 100 % particle-free filtration of all types of compressed air, carbon dioxide (CO₂) and other gases.

Steam filter
The Haffmans' Steam filter CPM^® - PDF, is a validated steam filter for 100 % particle-free steam filtration. Equipped with the patented, flexible Ecofilter^® element, consisting of filter membranes in between segmented stainless steel disks, the PDF offers the highest filtration efficiency and security.

The filter membranes of the steam filter are made of woven stainless steel threads that assure absolute filtration. Haffmans' CPM^® steam filter membranes can be supplied in a variety of pore sizes to meet your special requirements and allow for high flow capacities against very little pressure loss.
