Filter driers with a high drying capacity

The DMB/DCB bi-flow filter driers ensure that refrigerant liquid always flows through the filter drier from the outer side of the filter core towards the centre. In this way, all dirt particles are retained regardless of the flow direction.

DCB filter driers are composed of 80% Molecular Sieve with 20% activated alumina, which makes them a perfect core blend for systems that operate at high condensing temperatures and require high drying capacity. They are especially recommended for use with HCFC refrigerants and mineral oil and also with HFC refrigerants and polyolester oil. 

DMB filter driers feature a 100% molecular sieve core with a high drying capacity, minimizing the risk of acid formation (hydrolysis). They are recommended for use with HFC and HCFC refrigerants and polyolester oil.
