All sizes strictly follow OEM industrial standards, diversified inlet and outlet interfaces meet different pipeline matching demands, direct plug-and-play replacement without modification. It is the ideal aftermarket spare part for global HVAC maintenance technicians and auto parts wholesalers to solve air conditioning intermittent cooling, frosting blockage and refrigerant leakage faults.
Product detailed description
Different Optional Models, Diversified Ports & Sizes for Full Vehicle Coverage
We have launched 8 mature standard models (RDC-6510 ~ RDC-6517) to adapt to various original car interface requirements, covering mainstream thread types and cylinder dimensions used in global automotive air conditioning systems:
Thread types: 5/8-18 UNF female thread, metric M16×1.5, M18×1.5, M20×1.5 male thread multiple specifications;
Standard cylinder size: Φ60×200mm conventional size, Φ76×150mm short thick size optional; Each model has precise inlet and outlet aperture matching data, which can perfectly match passenger cars, heavy trucks, buses and construction machinery air conditioning pipelines of various brands. Wholesalers can stock full series models to meet all daily maintenance matching demands, avoiding inventory shortage caused by single specification limitation.
Thickened Seamless 3003 Aluminum Alloy Shell, Pressure Resistant & Zero Leakage
The tank body is integrally extruded from aviation-grade seamless aluminum tube, no split splicing and secondary welding. The cylinder wall is uniformly thickened, can withstand instantaneous high pressure surge of refrigeration system without expansion, deformation or rupture. All thread interfaces and end covers adopt precision vacuum brazing seamless welding technology, welding seams are fully fused without tiny gaps, virtual welding holes and air leakage hidden dangers. The inner wall is treated with anti-oxidation passivation coating, resisting refrigerant acid corrosion, refrigeration oil erosion and long-term high-low temperature alternation, permanently avoiding slow refrigerant leakage caused by shell aging and welding seam loosening.
High-Capacity 3A Molecular Sieve Desiccant, Efficient Permanent Moisture Absorption
The inner cavity is filled with high-purity spherical 3A molecular sieve drying particles, which is the most professional water absorbent for automotive refrigeration systems. Compared with ordinary silica gel desiccant, molecular sieve maintains ultra-high water absorption efficiency under low-temperature refrigeration environment, can continuously capture trace dissolved water vapor in liquid refrigerant, thoroughly eliminate ice clogging phenomenon of expansion valve. The upper and lower partition screens fix the desiccant tightly inside the tank, preventing particle shaking, pulverization and shedding into the pipeline to cause secondary pollution of the refrigeration loop.
Three-Stage Progressive Stainless Steel Filtration System, Block All Kinds of Impurities
Built-in multi-layer progressive filtering structure inside the drier, replacing the simple single-layer filter screen of cheap products:
Primary coarse filtration: Intercept large welding slag, pipeline falling debris and large metal fragments;
Intermediate precision filtration: Trap refrigeration oil sludge, carbon deposits produced by long-term compressor operation;
Final micron fine filtration: Block tiny abrasive particles that wear internal compressor parts. All filter meshes are made of 316 food-grade stainless steel woven material, corrosion-resistant, not easy to be blocked, keep the internal refrigeration system clean all the time, protect expansion valve and compressor core components from abrasion and jamming damage.
Dual Functions of Refrigerant Storage & System Pressure Buffering
As a refrigerant buffer storage tank, it can store redundant liquid refrigerant inside the loop. When the external ambient temperature changes greatly, it automatically adjusts the circulating refrigerant volume, balances the pressure difference between the high-pressure side and low-pressure side of the air conditioning system, avoids frequent high and low pressure protection shutdown caused by unstable pressure, and makes the cabin cooling output uniform and stable in all seasons.
Wide Compatibility & Extreme Climate Adaptability
Perfectly compatible with R134a and R1234yf two mainstream modern automotive refrigerants, covering fuel vehicles, hybrid vehicles, engineering machinery equipment worldwide. The whole assembly can work stably in the temperature range of -45℃ ~ +130℃, adapting to tropical high-temperature areas, northern frigid zones and coastal high salt spray humid environments, no attenuation of drying efficiency and sealing performance after long-term use.
1:1 OEM Standard Dimension Design, Direct Bolt-On Installation
The overall length, thread aperture, inlet-outlet direction and fixed ear positions of each model are completely produced according to OEM original drawings. No cutting pipelines, thread modification or bracket trimming is needed during replacement, the interface is tightly fitted with the original car pipeline, effectively preventing air from entering the closed system. Professional maintenance personnel can complete disassembly and assembly quickly, greatly shortening vehicle maintenance time.
Strict Multi-Stage Factory Quality Inspection
Every finished filter drier of all models will pass 6 professional testing procedures before leaving the factory:
High-pressure nitrogen holding air tightness test to detect overall leakage performance;
Molecular sieve moisture absorption capacity sampling inspection;
Multi-layer filter screen impurity interception precision endurance test;
High and low temperature alternating aging cycle test;
Vehicle driving simulation vibration fatigue test;
Thread interface matching precision calibration. All unqualified products with poor sealing, insufficient drying capacity and loose internal structure are completely eliminated to ensure consistent reliable quality of each batch of products.
Wide Application Scenarios
Passenger Vehicles: Sedans, SUVs, vans household air conditioning ice blockage and intermittent cooling fault replacement;
Heavy Commercial Vehicles: Pickup trucks, large buses, refrigerated trucks cab HVAC system supporting accessories;
Construction & Agricultural Machinery: Excavators, loaders, harvesters, tractors engineering vehicle air conditioning matching parts;
Global Auto Parts Wholesale: Repair shops and aftermarket distributors bulk stocking full series models to meet diversified matching demands.
Tangible Benefits After Replacement
Replacing the saturated and failed original filter drier with our RDC series multi-spec drying filter can completely solve air conditioner intermittent cold air, pipeline frosting and ice blockage problems, keep the internal refrigeration system dry and clean permanently. It effectively avoids expensive compressor corrosion and wear damage, reduces repeated refrigerant refilling and system overhaul costs. Diversified specifications meet all vehicle matching needs, OEM-level quality with affordable factory direct sales price, it is the most essential purification core accessory for long-term stable operation of all types of automotive air conditioning systems.
