Hermetic burn-out filter drier
Type DAS
Used in the suction line to clean up refrigeration and air conditioning systems
Hermetic burn-out filter driers type DAS are used in the suction line to clean up refrigeration and air conditioning systems after a compressor motor burn-out.
The solid core, which is composed of 70% activated alumina and 30% Molecular Sieve, adsorbs harmful acids as well as moisture.
Available with flare and solder (pure copper) connections.

Hermetic burn-out €lter drier, type DAS
Features
The Core type DAS
•Solid core with 70% activated alumina and 30% Molecular Sieve for adsorption of acid and moisture
•Recommended for use with HFO, HC, HFC and HCFC refrigerants
The Shell
•PED approved for PS 35 bar
•Available with flare and solder (pure copper) connections
•Corrosion resistant powder-painted finish
•Allows installation with any orientation provided the flow is in the arrow direction
•2 Schrader access valves to measure pressure drop across the drier
•Available in sizes 8 – 60 cubic inches
The Filter
• 120 mesh wire mesh provides solid particle retention with minimal pressure drop
Functions
Hermetic filter driers protect refrigeration and air-conditioning systems from moisture, acids, and solid particles.
By adsorbing harmful acids after a compressor motor damage, the DAS hermetic burn-out filter drier protects the new compressor against premature failure.

The large diameter of the hermetic burn-out filter drier means that flow velocity is suitably low and the pressure drop minimal.
Powder formation is eliminated because the solid core grains are bonded and cannot move against each other.
