The implementation of an equal pressure system is achieved through supplying air through ventilation shafts.

The uniform distribution of inlet elements determines 80% of the uniformity of the microclimate in the room. If fans are installed in the supply shafts, it is possible to realize an equal pressure system, which has the distinct advantage of being less dependent on external weather conditions, wind influence, and rapid temperature fluctuations. In the first case, the following conditions must be met: elimination of uncontrolled air leaks, ensuring airtightness with air distributors in the closed position, and during operation - the ability to adjust not only the volume and velocity of incoming air, but also its direction. In the case of using an equal pressure system, the requirements for room sealing are not critical. The system itself provides uniform distribution of clean air and removal of exhaust air.
