DQA Series Uni-flow Filter Drier
<!--<$[标题]>begin-->DQA Series Uni-flow Filter Drier<!--<$[标题]>end-->

DQA series uni-flow filter driers in refrigeration system are used to absorb moisture,collect and filter out the impurities. DOA series uni-flow filter driers installed at inlet of throttle element can ensure flow fluently and prevent throttle element from being blocked by collecting solid impurities in refrigeration system

FEATURES

•  Applicable for existing refrigeration oils and mixtures

•  High efficient in moisture absorption and filtering impurity water and other pollutants

•  50um filter screen can maintain high-efficiency filtration under the minimum pressure drop

•  ODF braze connection port is optional

•  The bracket structure effectively decreases vibration influence on internal compo-nents


OPERATION CONDITIONS

•  Applicable Refrigerants:R410AR32.R134a R404A. R507.R407C and R22 (For R290. please confirm before placing orders.)

•  Maximum Working Pressure： 4.6MPa；

•  Medium Temperature：-40℃ ~ 80℃；

•  Ambient Temperature：-40℃ ~55℃；

•  Relative Humidity: below 95%
