Steam Filters Eliminate Wet Packs and Stained Instruments, and Reduces Hospital Sterilizer Maintenance by Controlling Steam Quality!

 
A Parker Balston® Steam Filter designed specifically for use on Hospital Steam Sterilizers is available from Acme Concord Corp and addresses the following problems:
 
Caused by Dirty Steam:
  • Stained Instruments
  • Wet packs
  • Dirty sterilizers
  • Malfunctioning steam valves
 
Caused by Dirty Feed Water:
  • Deposits and stains on instruments
  • Tarnishing and staining of sterilizer
  • Increased sterilizer maintenance
Product Benefits:
Extensive hospital experience has shown that the Balston Steam Filter essentially eliminates instru­ment staining, spotting, and rusting caused by wet or dirty steam. Other benefits obtained by use of the Balston Steam Filter include:
 
  • Removes contaminants
    • Completely removes rust and dirt from steam
    • 98+% of all 0.1 micron particles and larger
  • Reduction in wetting and staining of sterilizer articles
    • Wrapped articles emerge from the sterilizer cycle drier as well as cleaner
    • Helps to eliminate wet packs by remov­ing excessive condensate in the steam
  • Significant reduction in staining of sterilizer interiors
  • Reduces operating costs by:
    • Expensive and time-consuming cleaning is greatly reduced or eliminated
    • Reduction in maintenance of sterilizer steam control valves, door seals, and other rubber materials in the sterilizer
  • Removes essentially all non-volatile boiler feed water chemicals
 
The 23/75SR Steam Filter also reduces drying cycles, saving and increasing productivity efficiencies. The filter tube is constructed from chemically inert borosilicate glass, and is completely free of impurities which could extract into the steam.
 
It exceeds the ASHCSP Steam Filter System Performance Recommendation outlined in Technical Document #031801 and complies with the FDA and are in full compliance with the requirements of the Health Protection Branch of Health and Welfare Canada.
 
Type 23/75SR Steam Filter: What it is, How It Works
The Balston Type 23/75SR Steam Filter contains a patented Microfibre® Filter Tube in a rugged stainless steel housing especially designed for steam service. Included as standard items with the Type 23/75SR are a stainless steel con­densate drain and high quality bleeder valve. The unit, as received, is com­plete, ready for installation. The filter is installed in the hospital steam line immediately upstream of the sterilizer control valve (refer to drawing below).
Steam enters the housing into an expan­sion chamber, where much of the con­densate is knocked out of the steam by the abrupt change in flow direction and velocity. The steam then flows upward in the housing, through the Grade SR Mi­crofibre Filter Tube and then downward to the exit port. The Grade SR Microfibre Filter Tube, rated at 98+% efficiency for 0.1 micron and larger particles, removes essentially all the suspended solid par­ticles and the remaining water droplets. The water draining from the filter tube and the expansion chamber is automati­cally removed from the housing by the automatic condensate drain.
The Balston Grade SR Microfibre Filter Tube, the heart of the Type 23/75SR Filter, combines rugged construction with remarkably efficient filtration of solid particles and liquid droplets. Solid par­ticles remain trapped in the depth of the filter tube, while liquid water drips from the filter tube to the automatic drain. The Microfibre Filter Tube is constructed from chemically inert borosilicate glass fibers and fluorocarbon resin binder. The filter tube is completely free of impurities which could extract into the steam.
 
 
Installation and Recommendations:
The filter is shipped completely as­sembled, filter element installed, ready to tie into your steam line. The recom­mended installation drawing shows the recommended method for installing the Type 23/75SR Filter. Inlet and outlet ports are 1” NPT for the Type 23/75SR. Since the filter weighs only 16 pounds, it can easily be supported by the steam line. No mounting bracket is required.
The filter should be installed on the upstream (pressure) side of the steril­izer steam control valve, as close as possible, to minimize condensation and pipe scale downstream of the filter. It is good practice to insulate the Type 23/75SR housing (up to the external compression ring) and the steam piping downstream of the filter to prevent condensation between the filter and the sterilizer.
Iron pipe should be replaced with non-corroding pipe (stainless steel) downstream of the filter to prevent ad­ditional contamination. Parker Hannifin recommends one Type 23/75SR on each sterilizer steam line. Please contact an Acme Concord application engineer if any other arrangement is being considered.
 
 
 
 
Changing Filter Tubes:
Since the Type 23/75SR is installed up­stream of the sterilizer steam control valve, it is exposed to steam at full line pressure at all times, regardless of the sterilizer operating schedule. Therefore, the filter tube should be changed every six weeks, whether or not the sterilizer has been used frequently during that period. If the filter tube is allowed to remain in service considerably longer than six weeks, the resin binder in the tube may weaken and the tube will no longer filter at its initial efficiency. Filter tube life is based on steam pressure of 50 psig or less. Tube life will be shorter at higher pressures. A tag on which the date of each filter tube change may be written is attached to the Type 23/75SR.
