NSHEV FS LIGHT/2 consists of 2 opposing opening sashes with an aluminum frame and either a glazed or solid infill. The opening mechanism consists of two single-acting pneumatic cylinders with the option of either a single-opening function or open/close function when connected to a remote pneumatic system with dual copper tubing.
The cylinders are hinged between shaped parallel brackets that allow the opening of the two sashes, with a 90° opening angle. They are controlled by a single thermal valve complete with a CO2 cylinder and a thermal fuse vial (with various adjustable settings).
The locking block, present on each sash, can be manually released from the outside for maintenance purposes. The NSHEV FS LIGHT/2 can be opened in case of emergency and can be closed from the ground if connected through a 2-pipe pneumatic system. The device can also be used for daily ventilation by adding 230V motors.
