Description
Sporlan Controls 404314 Bi-Flow Line Filter Drier
The Sporlan Controls 404314 is a 3/4″ ODF Bi-Flow Line Filter Drier engineered for reliable refrigerant circuit protection in heat pump and reversible refrigeration systems. Designed to handle refrigerant flow in both directions, this filter drier removes moisture, acid, and particulate contamination that can degrade compressor performance and shorten system life — regardless of which direction the refrigerant is flowing.
Why Choose a Bi-Flow Filter Drier?
Standard filter driers are directional and can restrict or bypass contaminants when refrigerant reversal occurs, as in heat pump defrost cycles. The Sporlan 404314 is purpose-built for bi-directional flow, making it the correct choice for:
- Heat pump systems that reverse refrigerant flow during heating and defrost cycles
- Reversible refrigeration circuits
- Applications where system direction may change during operation
Key Features
- 3/4″ ODF sweat connections for easy field installation
- Bi-flow design allows refrigerant flow in both directions without bypassing filtration
- Removes moisture, acid, and solid particulates to protect compressor and system components
- Desiccant core provides high moisture capacity for long service intervals
- Rugged steel shell construction for durability in demanding HVAC/R applications
- Sporlan Controls quality — a trusted name in refrigeration filtration and flow control
Typical Applications
- Residential and commercial heat pump systems
- Split system air conditioners with reversing valves
- Refrigeration systems requiring bi-directional filtration
- New installations and system changeouts or retrofits
Installation Notes
Install in the liquid line of the refrigerant circuit. The bi-flow design eliminates the need to orient the drier in a specific direction, simplifying installation. Always follow applicable refrigerant handling regulations and manufacturer guidelines during installation.
