Automatic doors are doors that open without a hand on the leaf, and the question buyers ask is which automatic arrangement suits a cleanroom opening. This guide answers that question at the level the product description supports, which is the lock and closer level, and it names the automatic mechanism as a confirmation item rather than describing one as standard. That distinction keeps the guide useful without overstating what is evidenced.
The stated starting point is the lock and closer position. The leaf carries a rounded lock operable with the elbow, and locks and closers are offered in multiple options, without itemisation by model. A closer is part of any door's operating set, automatic or not, because it controls how the leaf returns to its seals: the frame sealing strip and the rising sweep strip only work if the leaf arrives at them firmly and without slamming. Any automatic arrangement must therefore be judged together with the closer, the hinges, and the seals as a set, not as a drive unit bolted onto a leaf.
What is not specified is the automatic mechanism itself: no drive type, no sensor type, no opening speed, no hold-open behaviour, and no safety device is stated for an automatic cleanroom door on this site. A buyer who needs automatic operation should send the requirement as an explicit inquiry item, with the operating mode required, the traffic pattern, the clear opening, the hold-open need, the safety requirements, and the interface with any access control or airlock behaviour. Related terms for this guide include automatic sliding doors for clean rooms, treated the same way: the sliding leaf facts are stated, and the automatic sliding mechanism is a confirmation item.
Until an automatic arrangement is confirmed for a specific opening, the safe specification is a stated door family with its lock and closer requirements recorded, and the automatic requirement recorded as an open item. That approach lets the project proceed with door sizes, vision panels, and sealing settled, while the automation decision is made on a confirmed mechanism rather than on an assumed one. Please confirm the minimum order quantity and the lead time in the same inquiry, because this site publishes neither figure.
- Stated: rounded elbow lock; locks and closers in multiple options, not itemised by model.
- Not specified: automatic drive type, sensor type, opening speed, hold-open, safety devices.
- Judge as a set: drive with closer, hinges, frame seal, and sweep strip together.
- Send with the inquiry: operating mode, traffic pattern, clear opening, hold-open, safety, access interface.
- Related term: automatic sliding doors for clean rooms, same confirmation route.
- Until confirmed: specify a stated door family with automation as an open item.

How to read the specifications on this page
Dimensions and construction details on this page follow the Lairun product description for the component family shown. Door opening sizes quoted on this site are brochure dimensions: they describe the opening sizes listed in the product brochure, and any non-standard size should be confirmed in the inquiry. Aluminium profile codes are listed by code only; no profile dimension is stated where the product description does not give one. Items that the product description does not specify are marked for inquiry confirmation rather than described as available options, so buyers are not led to assume a mechanism, a load figure, or a material variant that has not been evidenced.
What to put in your inquiry
Send the opening sizes you need, the leaf arrangement, the surface finish you prefer, and the ceiling layout where the components will be installed. State the quantities per size, the site conditions, and the delivery location so the component list can be checked line by line. Where this page lists an item as subject to confirmation, include that item explicitly in your message so it is answered before any order is placed. Please confirm the minimum order quantity and the lead time in your inquiry, because this site does not publish those figures. Certificates are available upon request; please ask for the documents you need and state which project they are for.
