Hermetic sliding doors form part of the solutions that Manusa offers for laboratories, hospitals and environments related to the healthcare sector and all types of white rooms in industrial environments, where the air has special conditions.

With bi-part or single-slide options, Manusa’s sliding doors combine the advantages of an automatic door with the airtightness and hygiene required in clean environments.

The hermetic sliding door consists of one or two sliding leaves which move sideways automatically, opening up a wide clearance area for public transit whilst hermetically sealing the perimeter of the aperture once closed. It also allows the leaf to open in the event of a power failure, using a handle to open the door.

In order to guarantee correct hermetic sealing, the leaf drops down 15 mm towards the floor and fits 10 mm into the frame of the opening so as to seal the perimeter of the door opening.

Hermetic sliding door leaves are available in HPL, in AISI-304 and AISI-316 stainless steel (the latter being especially recommended for corrosive and saline environments), mixed (HPL and stainless steel) and glass*.

The low air permeability features of our doors are due to the airtight seal fitted around the entire perimeter for the leaf. The hermetic Visio + operator and the MK40 frame make it possible to guarantee the correct functioning of a hermetic sliding door on any type of wall. When the leaf/leaves close/s they approach the frame, sealing the perimeter of the door opening.

Manusa’s hermetic sliding doors have been tested with the aim of determining the product’s air permeability at low pressures. The tests have been performed with positive and negative overpressure on the sliding door.
