DFS filter

DFS filters are core components for media purification in refrigeration systems. Their high-efficiency filter elements intercept impurities and absorb moisture, protecting critical components like the compressor from wear and tear.
They are suitable for liquid and air intake lines in refrigeration, air conditioning, and refrigeration units.
They are manufactured with corrosion-resistant housings and high-contamination filter elements, tested for pressure resistance and filtration efficiency.
Pre-sales selection and after-sales filter element replacement guidance are provided. Advantages include precise filtration, corrosion resistance, wide compatibility, and easy maintenance.
The DFS filter is a key component for media purification in refrigeration systems. Its core advantages are significant: It utilizes a composite high-efficiency filter element that combines both impurity interception and moisture adsorption. It precisely captures solid impurities such as metal debris and welding slag in the refrigerant, while efficiently adsorbing residual moisture in the pipeline to prevent acidic corrosion caused by the reaction of moisture and refrigerant. Its high filtration accuracy and strong dirt-holding capacity make it non-clogging even after long-term use. It effectively protects core components such as the compressor and solenoid valve from wear and damage, extending the overall service life of the equipment. The housing is constructed of corrosion-resistant materials that withstand long-term attack from refrigerants and refrigeration oil, adapting to complex high and low temperature operating conditions. Its specially designed sealing structure prevents secondary contamination of the filtered media. The filter element is easily replaceable without disassembling the entire valve, reducing maintenance time and costs. Compatible with mainstream refrigerants such as R22, R410A, and R32, it eliminates the need to select a specific filter type based on the refrigerant, reducing inventory pressure. It accommodates a variety of piping connections, allowing for flexible installation without space constraints. It has a wide range of application scenarios, from the liquid pipelines of household central air conditioners and commercial refrigerated display cabinets to the suction pipelines of industrial cold storage and large refrigeration units. It can stably play a purification role, ensuring the efficient and safe operation of refrigeration systems of different sizes, helping users reduce the frequency of equipment failures and reduce long-term operation and maintenance costs.
