Bi-flow dry filter

Customized products Bi-flow dry filter

Used in refrigeration system pipeline with bi-flow or unidirectional flow to absorb moisture and h acid in the system and filter out impurities.

Technical parameters

  • Features
    • High efficient in moisture absorption, filtering impurity, acid, paint remains and mud removal
    • Hybrid desiccant
    • Solid filter cores are bound with desiccant which can minimize vibration and friction in system operation. And it also reduces the wear of desiccant.
    • Filtering fineness: 20?m
    • Corrosion resistant painting can survive salt spray test of 500 hours.
    • Connection type: thread or solder
  • General specifications
    • Applicable refrigerant: CFC, HFC, HCFC and HC
    • Applicable medium temperature: -30°C ~ 120°C (-22°F ~ +240°F?
    • Applicable ambient temperature: -30°C ~ 55°C (-22°F ~ +131°F?
    • Maximum working pressure: 4.83MPa (700 pis)
    • Certification: UL/CSA
  • Technical Parameters

    Note:

    • 1) For CFC system, usage of core with alumina is recommended as a strong capability to absorb acid may be needed.
    • 2) When the systems use oil with additive, it is not recommended to use a core with alumina.

    Note1:

    Filter Driers for liquid line are manufactured in compliance with ARI Standard 710. Maximum flow rate of liquid refrigerant at a differential pressure of 1psi is indicated by Ton which is based on the temperature of liquid refrigerant 86°F and the following mass flow:

    • 3.1 lb/min/ton R134a
    • 4.1 lb/min/ton R404A, R507
    • 3.0 lb/min/ton R22, R407C
    • 2.8 lb/min/ton R410A

    Note2:

    Data on water absorption is based on the following EPD (method: ASHRAE Standard 63.1):

    • 60ppm R22
    • 15ppm R12
    • 30ppm R502
    • 50ppm R134a, R404A, R507, R410A, R407C

    Note3:

    20 drops of water?1g (1cc)

    Note:

    The above data is based on cleaning system of ideal condition; after impurities accumulate in the filter, the flow will decrease.
