Purex Pulse Jet

Purpose and Methodology

The PPJ technology builds on the robust Purex 800i system, a market leader in extraction solutions for the coding industry. The PPJ unit uses compressed air to periodically clean filters, blowing debris into a collection tray for easy disposal. This system includes:

• Purex Pulse Jet Unit: Uses compressed air to clear filters, capturing the bulk of particles in a collection tray for safe disposal. The system uses F9 filters, capable of filtering up to 0.9 microns.
• Purex 800i: Generates the airflow that extracts particles through the PPJ. It uses a combination of pre-filters, HEPA, and carbon filters to capture even finer particles, ensuring clean air output.
• Collection Unit: Safely stores the particles collected by the PPJ, making disposal safe, easy and controlled.

Results

During testing, the PPJ system proved remarkable improvements to production efficiency:

• Cylinder filter lifespan: Required changing every 3 weeks, During this time an average of 28 million codes had been completed.
• Labyrinth pre-filter lifespan: 6 weeks before needing replacement.
• HEPA/Carbon filter lifespan: 10 weeks before needing replacement.
• Collection bin: The PPJ collection tray was emptied into the collection bin at the start of every 8 hour shift. It was filled every 4 weeks with a significant amount of captured debris.

This resulted in drastically reduced downtime, fewer manual interventions, and long-term cost savings for the customer.
