Bi-Directional Filter Driers Series STG/L
The filter driers of series STG/L are used in refrigeration system with bi-directional flow to absorb moisture and acid in the system and to filter out the impurities.
- High efficient in moisture absorption, filtering impurity, acid, paint remains and mud removal
- Hybrid desiccant
- Filtering fineness: 20µm
- Corrosion resistant painting can survive salt spray test of 500 hours
- Connection type: thread or solder
- Full dimensions, capacity and moisture capacity available on the Data Sheet download below
- Applicable for all common HCFC, HFC and CFC refrigerants such as: R22, R134a, R404A, R407C, R410A, R507
- Min./max. ambient temperature: -30°C to +55°C
- Medium Temperature TS min./max.: -30°C (-22°F) / +120°C (248°F)
- PS: 4,83 MPa (48.3 bar) 700 PSI
- Certifications: UL/CSA & PED Declaration

- 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.

Filter Driers for liquid line are manufactured in compliance with ARI Standard 710. Maximum flow rate of liquid refrigerant at a differential pressure of 0,07bar (1psi) is indicated by kW (ton) which is based on the temperature of liquid refrigerant 30°C (86°F) and the following mass flow:
- 0,40 kg/min/kW (3.1 lb/min/ton) R134a
- 0,53 kg/min/kW (4.1 lb/min/ton) R404A, R507
- 0,39 kg/min/kW (3.0 lb/min/ton) R22, R407C
- 0,36 kg/min/kW (2.8 lb/min/ton) R410A
Note: 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
Note: The above data is based on clean system at ideal conditions; with impurities accumulated in the filter, the flow may decrease.
