KK-bypass filters MF 100, MF 200-1, MF 200-2 and MF 250

Acid-resistant KK-bypass filters remove solid impurities from water, water-glycol solutions and process water. They can also be used for filtration needs in food and process industry. 

Fine iron particles are filtered from water/heat transfer liquid by permanent magnets. These particles can disturb the operation of water and glycol-based systems.

KK-bypass filters are manufactured in Finland. They can be tailor-made according to customer-specific needs such as structural changes and the number of magnets.
