Things To Consider When Planning a Cleanroom

Contact a ISO 17025 accredited 3rd party cleanroom Certification Agency to discuss your specific requirements as they have the experience from a service providers perspective that will save you $$$ on the front end and frustration once you are in operation. They also know experienced design firms and contractors that understand cleanrooms.

 

Whether your cleanroom is to be a "Stick Built" - "Hybrid" - "Modular Hardwall" or "Softwall", These are a few questions to ask your design team up front!

1. Determine the product process flow to see where the most effective placement of the HEPA filters in the ceiling grid will be!

2. Will the HEPA filters need to be challenged for certification.

3. Are the HEPA filter installers trained on installing the HEPA filters properly..

4. You need to set aside a lay away budget plan for the replacement of the HEPA filters.

5. When is it time to change the HEPA filters (Ask the filter supplier this question in the design stage)

6. What is the right sealant to be used for sealing wall/ceiling penetrations.

7. Will you need a  Pass-Thru or Air Shower.

8. Will the flooring be conductive or non conductive.

9. Will you be using a Central Vacuuming System or a Portable HEPA Vacuum.

10. DO NOT skimp on the size of the Gown Room.

11. Where are you going to store the custodial equipment and supplies.

12. Where are you going to store the extra garments.

13. When purchasing a softwall cleanroom, discuss with your vendor about room pressurization recommendations per ISO 14644-4 guidelines.

The Value of an On-Going Monitoring Program

Keeping your cleanroom and laminar flow bench operating at optimum efficiency is essential. This means having an active On-Going Monitoring Program (OGMP) in place, either by internal personnel or utilizing your Certification Agency on a more regular basis.

 

HEPA Filter Life Expectancy Check

Find out what the initial pressure drop of the HEPA filter is (this can be found on the side of the filter housing) and what the final recommended pressure drop is for filter replacement from the filter manufacture you are using.

Gage: Dwyer # 2001 ( 0.0-1.0” Wg.)            

Tubing size: 3/16”-1/4” ID (to fit the Dwyer hose fitting that comes with the gauge)

Drill a ¼” hole in the “Tin Can” portion (between the air inlet and above the HEPA filter media). of the HEPA filter housing and install the high side of gauge tubing.

Seal this penetration (tight) with a non-silicone approved sealant.

Run the tubing across the ceiling within the plenum to a corner of the cleanroom and drop this tubing down into the cleanroom to about 6 feet above floor level for ease of access to hook up a portable differential monitoring device (or the in-place Dwyer # 2001 gauge mentioned above and leave the low port open).

Make sure the ceiling penetration is also sealed with the approved sealant.

Repeat this sequence for each room you want to monitor.(using one HEPA filter in each area as a typical)

The monitoring and recording of each designated HEPA filter should be part of the certification visit and be part of a in-house monitoring program on a monthly basis.

 

HVAC System HEPA Filter Replacement:

Before you install new (replacement) filters in the holding frame, MAKE SURE that the holding frame is free of any debis that may allow air to by-pass the filter media. You DO NOT want any air to by-pass the filter media as it will show up on the filter challange and you will have to reseat the filter in the frame.
