Customer Background
The customer is a fine chemical manufacturing company located in Texas, USA, specializing in the production of coatings, resins, and industrial solvents. Its original filtration system utilized outdated multi-bag filters, which presented frequent maintenance needs, significant pressure differential fluctuations, and complex filter bag replacement procedures. These issues severely impacted production continuity and product quality.
Challenges and Requirements
The customer needs to handle various liquid media with different viscosities during the production process, including solvent-based coatings, synthetic resins, and high-purity additives. The core requirements are as follows:
The filtration accuracy is stably maintained at 100 microns, effectively removing particulate impurities.
The sealing parts should be oil-resistant and heat-resistant to adapt to the working conditions with a temperature below 100℃.
It is equipped with a pressure monitoring function, which is convenient for real-time tracking of the filter bag status.
Compact structure and convenient maintenance reduce downtime.
The interface complies with the ANSI standard, facilitating connection with existing pipeline systems.
Solution
Based on the customer’s working conditions and technical requirements, we recommend and provide the JYSF-#2/304 type stainless steel single-bag filter. The specific configuration is as follows:
Main material: 304 stainless steel, sandblasted, corrosion-resistant and easy to clean.
Structural form: Side-in and side-out, suitable for the on-site pipeline layout of customers.
Filter element: PE filter bag, 100 microns, plastic mouth fully hot-melt welded process, no bypass leakage.
Sealing material: Nitrile rubber, with excellent temperature and oil resistance.
Monitoring and Emission: Equipped with pressure gauges (NPT internal thread interface) at the inlet and outlet, a vent valve on the top cover, and a drain valve at the bottom.
Connection standard: ANSI B16.5 150# flange, seamless connection with the customer’s existing pipeline.
The customer purchased 30 units at one time, which were respectively deployed at multiple filtration stations on three production lines, achieving a standardized upgrade of the entire line’s filtration system.
Implementation Effect
After the batch of filters was put into operation, the customer provided the following feedback:
The filtration efficiency has been significantly enhanced: 100-micron filter bags effectively intercept the particle impurities generated during the production process, increasing the product qualification rate by approximately 8%.
Maintenance time is significantly reduced: The single-bag structure combined with the quick-opening top cover design enables filter bag replacement in just 5 minutes, reducing the single maintenance time by 60% compared to the original system.
Controllable and traceable operating status: The inlet and outlet pressure gauges help operators accurately determine the clogging condition of the filter bags, enabling preventive maintenance.
The equipment operates stably: 30 sets of equipment have been running continuously for 6 months without any seal leakage or abnormal pressure difference fluctuations, meeting the demand for 24-hour continuous production.
Simplified spare parts management: After unifying the model, spare parts such as filter bags and sealing rings have become universal, reducing inventory costs by approximately 30%.
Customer Review
“The JYSF series of filters has effectively addressed our previous issue of frequent machine shutdowns for filter bag replacements. The design is simple yet fully functional, with the pressure gauge and drain valve being particularly practical. By purchasing 30 units at once, we have not only standardized our entire line of equipment but also significantly reduced maintenance and spare parts management costs. The manufacturer provided comprehensive customization support, ensuring that everything from flange standards to sealing materials was tailored to our specific working conditions.”
