DMB / DCB
Hermetic bi-flow filter driers, types DMB and DCB are for use in liquid lines on heat pumps.
Hermetic bi-flow filter driers have built-in check valves which ensure that refrigerant liquid always flows through the filter driers from the outer side of the filter core towards the center. Thus, all dirt particles are retained irrespective of flow direction.
DMB and DCB filter driers ensure fast and effective adsorption of moisture as well as organic and inorganic acids.
When building heat pump systems, the use of bi-flow filters can, depending on the type of system, save up to ten solder connections. This reduces production costs and the number of potential leakage points.
Available with flare and solder (copper and cu-plated steel) connections. For other connections please contact your Danfoss sales representative.

- The Filter is available in sizes 05 – 60 cubic inches
20% more moisture 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 center. 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.
