Core Functions
Three-level Progressive Precision Filtration
It adopts three-stage sequential filter bottles for filtration, successively intercepting sand, rust, colloids, fine suspended substances, and oil and dirt impurities, protecting the flowmeter, solenoid valve, precision instruments, pneumatic-hydraulic components, and sampling pipelines of DCS analysis instruments, avoiding pipeline blockage, equipment wear, and measurement distortion.
Multi-condition Medium Adaptability
It can be used for process cooling water, instrument compressed air, water sample sampling medium, hydraulic oil, circulating pure water, etc. and is suitable for pre-treatment circuits of online analysis systems in power plants, chemical industries, and metallurgy.
Convenient Maintenance Design
Each filter bottle is independent and detachable, allowing for the replacement of corresponding precision filter elements separately; the filter bottle is equipped with a pressure relief valve as standard, enabling safe pressure relief before replacing the filter element to avoid high-pressure splashing; an external differential pressure gauge can be connected to monitor the degree of filter element blockage intuitively and predict the replacement cycle.
Corrosion-resistant and Pressure-resistant Structure
The filter bottle shell is made of reinforced polypropylene / stainless steel (optional), with an EPDM corrosion-resistant sealing ring inside, resistant to acids and alkalis, and able to withstand industrial corrosion, suitable for complex industrial fluid conditions.

Typical configuration scheme for the fourth and fifth stages of filtration
First stage (pre-filter): melt-blown polypropylene filter element (20μm), intercept rust, sand, large particle impurities, protect the secondary precision filter element
Second stage (intermediate filtration): wound/folded filter element (5μm), remove colloids, fine suspended matter
Third stage (terminal fine filtration): precision folded filter element (1μm), ensure clean medium input for the rear-end instruments and sampling circuits
Typical application scenarios
Power plants, chemical DCS online flue gas / water quality analysis instrument sampling pre-treatment system, filter process water samples, condensate liquid of sample gas
Air compressor instrument air, hydraulic lubrication system oil circuit pre-filter, protect precision valves, cylinders, flow sensors
Pure water circulation system, electroplating, coating process fluid pre-filter
Replacement of old fluid pre-treatment equipment parts, maintenance and renovation of filter devices in analysis cabins
