Auto Backwash Filtration System (ZBAG)
Fully Automatic Fine & Micro Filtration for PT and E-Coat Baths
The Challenge
- Welding beads and metallic fines
- Dust, fibres, glue residues
- Paint particles and soft contaminants
Conventional filtration methods struggle to remove both heavy and fine particles efficiently.
Disposable filters increase operating cost, create waste, and interrupt production.
Manual cleaning and frequent filter replacement reduce process continuity.
The JMXworks Solutions
The JMXworks Auto Backwash Filtration System provides continuous, high-efficiency filtration without stopping the process.
Its patented backwash technology cleans the filter media automatically using a very small quantity of already filtered liquid — while filtration continues.
Result: Cleaner baths, longer bath life, and stable process conditions.
How it Works?
- Contaminated bath liquid passes through a fine woven or metal-fibre filter media
- Particles are retained on or within the filter surface
- Once a defined contamination level is reached, automatic backwashing is triggered
- A small quantity of clean filtrate removes the retained particles
- Filtration continues uninterrupted during backwash
The system maintains high filtration efficiency with minimal reject loss.
Why ZBAG is Different?
Unlike disposable bag filters, belt filters, hydrocyclones, or magnetic separators, ZBAG:
- Filters fine and micro particles down to 1 µm
- Handles high flow rates with low pressure loss
- Operates as a fully closed system
- Requires no frequent manual intervention
- Delivers very low backwash quantities
This makes it ideal for critical PT and E-coat bath purification Autoback wash Filtration System
Key Benefits
- Continuous filtration without production stoppage
- Very high backwash efficiency (patented design)
- Lowest possible reject quantity
- Filter fineness from 1 µm to 200 µm
