Instructions for maintaining solvent quality with Puritan^® LF Cartridges®

 
When to Change Puritan Large Format Cartridges:

Solvent flow rate is the best method for determining when to change cartridges.   Replace cartridges when fill time through the filter exceeds 1.5 minutes to reach working level.

Unfortunately, many machines fill to working level directly from the tank to the wheel, bypassing the filter.  In order to accurately check the fill time throughout the life of the cartridges, the machine must be reprogrammed to fill to level through the filter.  Filling in this manner also eliminates the risk of allowing any contaminants that may be in the base tank to be deposited on the garments in the wheel.

If reprogramming is not possible, then change cartridges either when the pressure exceeds 20 psi or when solvent color cannot be maintained to an acceptable level.

How to Change Spent Puritan Cartridges:

1.  Follow filter system manufacturer’s instructions for solvent recovery process from spent cartridges.  Allow cartridges to drain at least 24 hours.

(CAUTION:  Check solvent storage capacity of your drycleaning system before draining filters.)

2.  Before removing cartridges from their housing, consult solvent MSDS for safe handling information.

3.  Remove used cartridges and felt gaskets from housing or solvent recovery unit without spilling or dripping solvent.  Handle in accordance with all federal, state and local regulations governing disposal of hazardous waste*.

4.  Install new Puritan Large Format Cartridges according to detailed instructions enclosed with the felt gaskets.Be sure that all felt gaskets are in place to prevent soil bypass and all housing gaskets are properly fitted to ensure effective filtration.

5.  Reinstall cover(s) and check all valves for proper setting.  Close all drain valves and air vents.

6.  Fill filter and circulate, bleeding air vent lines until filter is liquid full.

7.    Circulate solvent through the filter for twenty minutes or until sight glass clears, whichever occurs last.  When using the Puritan Adsorptive Cartridge, it is important not to add detergent to the system until after this step, in order to achieve maximum filter effectiveness.

8.  Clean 2-3 dark loads before cleaning a light or white load.

 

How to Obtain Maximum Cartridge Life:

1.  Follow filter manufacturer’s operating instructions.

2.  Do not exceed an operating pressure of 20 psi as cartridges can be damaged by pressures over 20 psi.

3.  If cartridges are changed based on pounds cleaned, change when approximately 1,250 lbs. have been cleaned per split cartridge. 

4.  Maintain solvent temperature between 70°F-90°F.

5.  Vent the air from all filter housings daily.  (Cover air bleed vent with rag while slightly opening to prevent spilling or dripping of solvent while venting air.  Vent until solvent starts to drip from air bleed vent, then close vent tight and dryclean rag.)

 

Use of Detergent or Additive:

1.  Charge System:  To maintain a 1.3% detergent charge, add 17 oz. detergent per 10 gallons of new, distilled, or reclaimed solvent added to work system.  If Puritan Adsorptive Cartridges are installed, add an additional 4 oz. of detergent per new cartridge.

2.  Load Process System:  To condition the solvent, add 1 oz. detergent per 10 gallons of new, distilled, or reclaimed solvent added to work system.  If Puritan Adsorptive Cartridges are installed, add an additional 4 oz. of detergent per new cartridge.

 

IMPORTANT!  Read gasket instructions before installing cartridges.

* IMPORTANT!  Spent cartridges containing solvents listed as hazardous should be handled as hazardous waste and disposed of in accordance with applicable federal, state and local regulations governing hazardous waste disposal.

 An important success factor for any cleaning business is the ability to consistently satisfy customers by returning garments that look as fresh and clean as new.  Good filtration is essential to achieving that objective and avoiding the negative effects of graying and redeposition of soil that can lead to unhappy customers. That’s why Puritan filter cartridges are designed and constructed to trap and hold substantially more insoluble soil than competing brands

Differences in cleaning machine configurations, cleaning processes, solvents, and the work processed means that there are differing requirements for contaminant removal from one cleaning system to another.  So whatever your requirements, there is a Puritan model especially designed to meet your needs.

Superior Design, Materials, and Construction Deliver Better Value..

• Puritan  large format cartridges provide up to one third more usable surface area than other brands.  With more premium filter paper and precise, deep pleating, Puritan’s extra surface area holds more dirt and lasts longer
• For superior removal of dye and other color impurities, only the best activated carbon  granules are used. The core is vibratic packed to full capacity to ensure no settling occurs.
• In the Puritan Adsorptive model, activated clay supplements the activated carbon in a uniform blend that ensures consistent removal of contaminants.
• The unique two-handle design does not puncture the filter shell, avoiding the soil bypass that occurs in other brands, and making for easier handling during filter changes.
• The paper ends are sealed in a bed of adhesive and bonded to the endplates while the side seam consists of a full pleat overlap that is interlocked and sealed with adhesive to prevent soil bypass and ensure structural integrity.
• Every case of Puritan large format cartridges includes new felt gaskets to ensure proper sealing.
• Every Puritan cartridge  is backed by the technical support capabilities of Street’s. Access our expertise through your area Street’s representative, on our website, or via telephone to our technical help line.

The LF

Balanced Filter Life and Dye Control for Most Systems

The LF is the standard large format model filter cartridge. It features a core of activated carbon that is sized to balance the dirt holding capacity of the filter paper to the dye removal capacity of the carbon core, in a ratio that is right for most systems using distillation to help remove solvent soluble contaminants.

Dye Eater

For Maximum Control of Dye Contaminants

The premium Dye Eater model features the same capacity for insoluble soils as the LF model, but uses a much larger core of activated carbon for extra dye removal capability and longer life.

Adsorptive

For Oily Contaminant Control in Systems Without Distillation

The Adsorptive model uses a core with two adsorptive materials. Activated clay is uniformly blended with activated carbon to provide some removal of oily contaminants in systems that lack distillation capability.

All-Clay

For Oily Contaminant and Moisture Control in Systems Where Carbon is Not Desired

The All-Clay model uses a core with 100% activated clay for removal of oily contaminants and unwanted moisture in systems that lack distillation capability.
