Rosedale Engineering Standards are the property of Rosedale Products, Inc.  A Rosedale Standard or copy thereof shall no be distributed (except with express approval of 
Rosedale Products, Inc.) to any individual or firm beyond the intended recipient firm or individual.  Firms of individuals acting contrary to the above may be subject to 
suit, ineligibility for continued or future employment, or removal from Rosedale’s “Approved Manufacturers and Specialty Contractors List”. 
 

 

 

Once the desired service flow has been established, the filter will operate efficiently until dirty.  
However, under no circumstances should more than 

15 PSI Differential Pressure 

through the filter be 

obtained.  Operating the filter unit with a high differential may cause filter bags to rupture and/or cause 
damage to filter system and downstream equipment. 
 
To prevent excessive drop through the filter unit, regular inspection of the filter media is required.  
Monitoring of differential pressure through the housing can be utilized as a means of determining 
whether or not the filter media needs cleaning or replacement. 
 
When it becomes necessary to clean or replace filter media, follow the procedure outlined below: 
 
 

1.  First close the flow from the inlet service line. 

 

2.  Close the flow to the outlet service line.  (In some applications closing flow to 
outlet is not required.) 

 

3.  Relieve the pressure from the filter unit. 

 

 

 

 

 

4.  Drain housing sufficiently to access filter basket. 

 

5.  Remove the cover by turning the cover counter-clockwise.  Remove the bag hold-
down device. 

 

6.  Remove filter bag and replace (if applicable) and throw away.  (Cleaning and 
reusing the filter bag is not recommended.) 

 

7.  Remove debris and sludge from inside the inlet portion of housing to avoid 
interference with cover seal or flow of fluid being filtered. 

 

8.  Install new filter bag (if applicable).  Place the basket into the filter housing, make 
sure the basket flange is fully seated into the basket collar in the vessel.  If applicable, 
insert bag into the bag basket making sure filter bag ring is firmly seated inside the 
basket ring in the vessel.  For best results, be sure filter bag is installed fully extended 
to the bottom of the basket. 

 

10. Inspect cover gasket for cuts or other signs of failure and make sure it is properly 
seated. 

 

11. Move cover back into position, Install cover by turning clockwise till seated on 
the o-ring.  Once initial contact with o-ring occurs, tighten approximately one half 
turn.  The application of process fluid (to wet seal) or lubricant will make it easier to 
install cover for a sufficient seal.
