Grubb Filtration possess the knowledge of filtration equipment, processes and applications necessary to convert the data and observations into conclusions which address the client’s problems and needs.

 

Here is a summary of the standard protocol for analysis of used pulse-jet filter bags:

 

·          Check the weight of the as-received bag and after any loose dust falls off during initial handling

·          Measure the dimensions — length and flat width

·          Determine fabrication details

·          Perform a careful visual inspection (inside and out) for wear patterns, failures, stains, discolorations, dust deposition, crust formations, cage wire impressions, fabric creases, etc.

·          Permeability profile … three measurements each at the top, middle and bottom of the bag — as received and after vacuuming

·          Mullen burst profile … three measurements each at the top middle and bottom — after vacuuming

·          Check the weight per square yard dirty, vacuumed and washed (and calculate the dust loading from the differentials)

·          Check the fabric physical characteristics of the washed samples (fiber, scrim, finish, permeability, etc.)

·          Prepare a written report presenting the observations and test data, and commenting on the significance of this information with reference to typical used bags, as well as to any specific conditions or problems in operation

 

The specific test procedures would vary somewhat for other types of bag (shaker or reverse-gas rather than pulse-jet) and would depend on the specific needs of the client.

 

The estimated cost for standard used bag analysis is five (5) hours for the first bag and three (3) hours for any subsequent bags in the same set tested at one time. See the accompanying fee schedule for our current rates.
