The air intake control system is all pneumatically controlled, safe to operate, and has protections against explosion, overload, short circuit, phase failure, and leakage. It also has automatic shutdown protection for over-temperature and under-voltage, automatic alarm without shutdown for oil separator blockage, oil filter blockage, and air filter blockage, as well as pneumatic pressure switch and safety valve protection to prevent over-pressure operation.

It uses an advanced single-chip microcomputer as the main controller and is equipped with a high-fidelity speech generator chip (the voice can be modified according to user needs; it is equipped with 8-way contact input control, which can send out 8 different alarm sounds.

The original third-generation high-efficiency screw compressor main unit is adopted, and the gap between teeth is small, so the return loss is small and the energy saving is significant.

Directly or remotely control the starting and stopping of explosion-proof motors for mining. It is used in coal mines and surrounding media with explosive mixed gases such as methane and coal dust.
