Air-tight sliding door

SAR40

Satisfies the A-4 grade of airtightness performance while maintaining light movement

Air-tight sliding door SAR40 is characterized by its capability of opening/closing with relatively light force while maintaining a high airtightness performance by minimizing drop-in and push-in movements that are required for air-tight sliding doors. In addition, it is a sliding door that satisfies the A-4 grade, which is the highest grade in JIS airtightness performance, with three-side frame structure that eliminates the bottom frame, which otherwise becomes an obstacle when people and carts pass through the door. ^*1 When installing on a heat-insulating panel system, opening frame and rail can be attached without inserting a special foundation, same as conventional sliding door series. ^*2 Three types of open/close mechanisms are available: manual, self-closing, and automatic. Rail cover can be changed to sanitary cover (slanted cover) as an option.

Hanger type three-side frame structure that does not create obstacles on the floor.
Satisfies the A-4 grade of airtightness performance with three-side frame structure. ^*1
When unevenness exists on the floor surface, a stainless doorsill is optionally available to eliminate floor scraping work.
In addition to the light door weight, opening/closing with light force is achieved as the result of minimizing drop-in and draw-in movements. ^*3
The bellow rubber around the opening is equipped with adjusting function that allows the adjustment of the touching condition between the packing and door.
Foundation insertion into the panel is not required when installing opening frame and rail.^*2
Lock systems of Miwa Lock can be incorporated.
Fully custom-fabricated in the unit of one millimeter.

^*1Prerequisite is that unevenness or inclination does not exist on the floor surface. Otherwise, the airtightness performance of the bottom portion is not guaranteed.
^*2Foundation may be required depending on the size of door and/or rail.
^*3Individual differences exist in the feel of lightness. In addition, this door will feel heavier as compared with typical sliding doors of the same size.
