[labnetwork] Cleanroom rollup doors

[Mark Alavi]

Hello All,

Some additional information for your use.

In Cleanrooms, we typically use these kinds of doors for tool/equipment move-in/move-out (MiMo), so they're used less frequently than main entry doors.
We typically design them so they are not near any sensitive equipment/tools. And if we can fit a vestibule type space, to allow for better pressurization control, we will do that. Also provides a staging area prior to moving into the cleanroom proper.

types of drawbacks to look out for, depending on the door:

  *   Possible air leakage at the door interface, not critical in a positive pressure environment, but existing systems may struggle to maintain pressurization if not originally designed for this.
  *   May have temperature and humidity deviation at the door location, so want to look for what's in close proximity and if there's any layout risks
  *   Could develop particles from wear and tear of mechanical components during operation
  *   Lubricants may not be semiconductor cleanroom compatible
  *   Depending on location of roll-up door, noise may be an issue from exterior activities

Hi Nick and all....
Good to know that these MIT.nano high speed Rite Hite  doors held up and are not awful to maintain through a lot of tool moves....
Roll up doors are less common as a direct door to a Cleanroom with no buffer zone, since they will shed particles from overhead when moving up and down.
Roll up doors  are usually a final barrier to a non clean area,  removed in distance  from the large sliding doors like the Rite Hite high speed sliding doors. Sliding doors also take up less horizontal space, close much more quickly  (usually programmable) and are easier to clean and keep clean and replace only non functional parts.

Hi Joe,

We we have a pair of high speed bi-parting doors (https://www.ritehite.com/en/am/products/industrial-doors/high-speed-doors/splitsecond) at the lv1 back of house tool wipedown.

Ours are very large (10'x10' clear) and leak at the seam/floor, the fabric at the window recently ripped and we have had to replace a couple photoeye's...But given the punishment they endure (opening hundreds of times per day for years on end during our fitout), they have proven remarkably reliable. We run them with virtually no preventive maintenance, and they're far more robust than mechanical doors that close against pressurization.

Best,

Hi there, we are looking for solutions for oversized doors.  A suggestion was a cleanroom rollup door (link below).  Have any of you used this type of product before?  Are there any drawbacks or maintenance issues you've experienced?
