Reverse air filters:

Reverse air filters are for hot metal, foundry, asphalt and similar heavy duty processes; also models for high volume wood waste and furniture production.

Dantherm Filtration produces a number of reverse air filters:
 

• FS Flat Bag Filter
  FS dust collectors are robust reverse air (reverse fan) cleaned filters with horizontally mounted flat fabric bags. They are commonly used in foundry dust and asphalt manufacture processes and similarly challenging applications.
   
• NF3000 negative pressure filter
  The NF3000 is our negative pressure version of our long standing NF dust collector line.
   
• NFK Bag Filter
  NFK dust collectors are modular reverse air (reverse fan) cleaned filters with tubular fabric bags. They are particulary suited to high volume wood waste applications or similar processes with light weight free flowing dust.
   
• NFP Bag Filter
  The NFP reverse air, dust collector is suitable for light dust loads and is available in OPEN or CLOSED panel construction. It also has the option for manual or reverse air cleaning.
   
• CS Bag Filter
  The CS is a larger, reverse air, dust collector suitable for medium sized dust loads with various hopper discharge options.
