Explosion-proof PSA nitrogen generators are mostly used in chemical, petroleum, natural gas and other fields; this type of nitrogen generator needs to deal with flammable and explosive environments, so in design, explosion-proof will be used for motors, electrical control, and nitrogen generators. At the same time, it is also necessary to prevent sparks, arcs and dangerous gases caused by electrical grounding and short-circuiting of electrical equipment. In the case of mine explosion protection：

 Air compressor

1. The motor is explosion-proof, with explosion-proof mark ExdI, and the protection level is IP55;

2. The motor is equipped with a soft start explosion-proof device, with the product explosion-proof mark ExdIIBT4, and the protection level is IP54;

3. It is required to be able to operate fully automatically under unattended operation;

4. Electrical control box with explosion-proof mark ExdibI;

5. Except for the motor, other electrical components of the air compressor have the explosion-proof mark ExdIIBT5, and the protection level is IP55.

 Air pretreatment device

It adopts refrigerated dryer with explosion-proof mark ExdembIIBT4.

Nitrogen generator

1. Pressure swing adsorption (PSA) nitrogen generator (carbon molecular sieve type);

2. The electrical control box has the explosion-proof mark ExdeIIBT5, and the protection level is IP56;

3. The main engine adopts all explosion-proof boxes.

Considering the mobility and convenient installation of the explosion-proof PSA nitrogen generator, the explosion-proof PSA nitrogen generator can be skid-mounted to facilitate the use of multiple working faces or mines. At the same time, the protection level of the equipment can be placed in the open air without Not affected. Although the explosion-proof PSA nitrogen generator has various protection functions such as over-temperature and over-pressure compared with the ordinary PSA nitrogen generator, there is no difference between the two in terms of other performance parameters.
