Project Overview
Client: A World-Renowned Coating and Paint Manufacturer
Key Challenge: Extreme labor intensity and production downtime caused by high impurity loading, requiring 6–8 filter bag changes per day.
Solution: CMI Automatic Self-Cleaning Scraper Filter System replacing traditional bag filters.
The Problem: A Production Bottleneck
The client operated a high-viscosity coating production line with a heavy impurity load. Their traditional bag filtration system reached maximum differential pressure approximately every three hours, creating a serious production bottleneck.
- Operational Strain: Workers were required to replace filter bags 6 to 8 times every day.
- Production Losses: Each bag change required line shutdown, reducing throughput.
- High Waste: Consumable bag costs and product loss during change-outs reduced profitability.
The CMI Engineering Solution
After a full evaluation of operating parameters, fluid viscosity, and contamination characteristics, CMI engineers recommended a complete process upgrade by eliminating the bag filter housing entirely.
The line was converted to a CMI Automatic Self-Cleaning Scraper Filter designed for continuous operation under demanding coating service conditions.
- Continuous Operation: Impurities are automatically removed from the screen surface while flow remains online.
- Low Maintenance: No repeated manual bag replacement required.
- Precision Configuration: System matched to the viscosity and solids loading of premium coating products.
- Robust Stainless Construction: Suitable for industrial coating environments.
Impact & Results
The transition to CMI’s automated filtration solution delivered immediate operational and financial improvements.
- Zero Consumables: Permanent stainless steel filter element eliminated daily filter bag usage.
- Uninterrupted Production: The line now operates continuously without shutdown for filter maintenance.
- Labor Reallocation: Operators were reassigned to higher-value production tasks.
- Enhanced Safety & Hygiene: Reduced manual handling of coating media improved the work environment.
Conclusion
The client expressed strong satisfaction with the upgrade. This project demonstrates that replacing disposable filtration methods with automated self-cleaning systems is a highly effective path toward modern, efficient industrial processing.
At CMI Filtration, we help manufacturers turn recurring maintenance problems into long-term productivity gains.
