Cartridge dust collectors
Pleated cartridge collectors give you a large filter area in a compact housing. Reliable pulse cleaning keeps the pleats open and the pressure drop low.
In a cartridge collector, dust-laden air enters the housing and passes through pleated media cartridges. The dust stays on the outside of the pleats while clean air leaves through the top of the cartridge. As the dust cake builds up, differential pressure rises and airflow drops.
Reverse pulse jet cleaning restores that airflow. A diaphragm valve on the compressed air header releases a short, powerful pulse into the clean side of the cartridge. The shock wave flexes the media, releases the dust cake and drops it into the hopper, all while the collector stays online.
Typical installation
- Compressed air header tank or manifold sized to the number of cartridges
- Goyen or Mecair diaphragm valves, immersed or flat mount, one per blow pipe
- Remote pilot valves in an enclosure, or integrally piloted valves on the tank
- A sequencer or filter cleaning controller in continuous or on-demand mode
Common challenges
- Pulse too weak to clean the full pleat depth, so pressure drop keeps climbing
- Fine or sticky dust bridging between the pleats and blinding the media
- Valves cycling far too often, which wastes compressed air and shortens cartridge life
- Diaphragms failing early because of moisture, oil or the wrong repair kit
Industries
- Metalworking
- Welding and cutting
- Woodworking
- Pharmaceuticals
- Food processing
- Chemicals
Questions
How often should a cartridge collector pulse?
As little as possible. On-demand cleaning triggered by differential pressure typically uses far less compressed air than a fixed timer and extends cartridge life. A controller with a differential pressure input lets you set the start and stop thresholds.
Which valve size suits a cartridge collector?
Most cartridge collectors use 1 inch to 1.5 inch diaphragm valves. The choice depends on the number of cartridges per blow pipe, tank pressure and pipe length. Send us the collector drawing and we calculate the right size.
Can I replace another brand of valve with Goyen or Mecair?
In most cases yes. We match the connection, orifice and mounting so the new valve fits the existing blow pipe. Send a photo and the part number stamped on the body.
Why does the pressure drop stay high after cleaning?
That usually points to a weak pulse: low tank pressure, an undersized header tank, a worn diaphragm or a blocked pilot line. Checking the tank volume and the diaphragm kits solves most cases.
