DAC Worldwide’s ACR Liquid Line Filter/Drier Cutaway, Bi-Directional (373-602) is a carefully-crafted, sectioned example of a commonly-encountered liquid line filter/drier. Liquid line filter/driers are designed to protect refrigeration system components from the negative effects of entrained water, formed acids and debris. These simplistic protective devices act as guardians for expensive system compressors, evaporators, and metering devices. Due to the reversing characteristics of heat pump systems, bi-direction on devices such as this example is required.

DAC Worldwide’s ACR Oil Separator Cutaway, Helical-Type (373-722) is professionally-crafted, economical teaching aid which depicts a conventional helical-type centrifugal oil separator commonly used in industrial and commercial refrigeration systems for oil entrapment and compressor crankcase replenishment.
