Clean Room Doors – Buyer FAQ

Clean Room Doors – Buyer FAQ

What clean room doors does LESHO make?

LESHO lists clean room sliding doors and a standard stainless steel swing clean room door for pharmaceutical laboratories on leshochina.com. They are intended for pharmaceutical, laboratory, electronics, hospital and food environments. Other catalog variants include hermetic (airtight) clean room sliding doors and clean room emergency exit doors with panic hardware.

What makes a door suitable for a clean room?

Clean room doors have flush, smooth surfaces without ledges where dust collects, sealed joints, airtight gaskets, cleanable materials (stainless steel, powder-coated steel or HPL), and flush vision windows. They help maintain pressure differentials between rooms of different cleanliness classes.

Which standards are relevant to clean room doors?

Clean room classification follows ISO 14644-1, and pharmaceutical facilities follow GMP rules such as EU GMP Annex 1. Doors are not certified to ISO 14644 themselves, but they must support the room's airtightness, cleanability and pressure cascade. LESHO catalogs list GMP-oriented sealing and CE/ISO 9001 marks; clean-room-specific test files are available from sales on request.

Sliding or swing clean room door?

Swing doors are simple and seal well for personnel airlocks and labs. Automatic sliding doors suit hospitals and areas with carts or trolleys, reduce hand contact, and can be hermetic (airtight) for operating rooms and isolation rooms. Choice depends on traffic and airtightness needs.

What materials are available?

Common clean room door materials are 304 or 316 stainless steel, powder-coated galvanized steel, and HPL panels, often with aluminum honeycomb or paper honeycomb cores. LESHO hermetic sliding doors use cores of paper honeycomb, aluminum honeycomb or rock wool, with electrostatic powder, fluorocarbon or 304 stainless faces; swing doors include stainless steel options.

Can clean room doors be interlocked?

Yes. Airlock (interlock) systems prevent two doors of a pass-through or airlock from opening at the same time, protecting the pressure cascade. Interlocks use magnetic locks, door sensors and a controller. LESHO clean room sliding operators support interlocking with sensors (hand/foot/IR/microwave); confirm interlock controller scope per airlock design.

Do clean room doors have vision windows?

Most do. Clean room doors normally use double-glazed, flush-mounted windows sealed on both faces so there is no ledge for dust. Window size and shape (square, round-cornered) are usually customizable. LESHO clean room doors use double tempered flush-mounted vision windows; size and shape confirmed per project.
