♦ PSD-Ex Series—Explosion-proof Industrial Vacuum Cleaner
为特点，相对于其他工业吸尘器结构简洁，实用、经济实惠。 PSD-Ex series products are characterized by safety and explosion protection . Compared with other industrial vacuum cleaners, the structure is simple, practical and economical. Applicable to continuous operation of flammable and explosive dust or supporting industrial equipment. Widely used in metal processing, plastic sheet processing, batteries, casting, electronics, 3D printing and other industries.
PSD-Ex series ♦ Explosion-proof motors, eliminating hidden dangers of electrical sparks
方面采用国际先进的防爆精铸涡轮风机（气泵），宽压双频，高可靠、低噪音、长寿命、可24小时持续工作。 The power system adopts international advanced explosion-proof precision casting turbine fan (air pump), wide pressure dual frequency, high reliability, low noise, long life, and can work continuously for 24 hours. The power is selectable from 0.25kw-4.0kw, and the power is 380V / 50Hz.
♦ Anti-static filter, eliminate the hidden danger of static sparks
方面采用滤筒式过滤器。 The filter system uses a cartridge filter.
The cartridge filter is treated with aluminized film on the surface, which has good antistatic performance and surface resistance ≤10 ^ 5Ω.
♦ Explosion-proof switch
方面采用隔爆型防爆开关，防爆标志：Ex d Ⅱ BT4 。 For the control system , an explosion-proof explosion-proof switch is used, and the explosion-proof mark is Ex d Ⅱ BT4.
♦ Negative pressure monitoring, dust removal reminder
是整机标准配置元件，是普华公司专门为工业吸尘器定制，绿、蓝、红分别对应各功率段机器内部负压情况，指针指向红色区域代表过滤器需要进行清灰或者更换。 The negative pressure gauge is a standard configuration component of the whole machine. It is customized by Puhua for industrial vacuum cleaners. Green, blue, and red correspond to the internal negative pressure of the machine in each power segment. The pointer points to the red area to indicate that the filter needs to be cleaned or replaced.
♦ Industrial casters, easy to move (optional)
安装简单方便。 Installation of industrial casters is simple and convenient. The wheels are made of top-grade polyurethane (PU), and the bracket is made of 2.5mm pickling plate to increase the reinforcement. Each 2 inch caster can carry 50kg. The tread design of the wheel surface enhances the anti-skid performance.
Dust removal system, efficient and reliable
清灰模式，根据不同工况选择不同振尘方式。 In terms of dust cleaning system , manual rotating dust vibration dust cleaning mode is adopted, and different dust vibration methods are selected according to different working conditions.
♦ Anti-collision guardrail and noise reduction design
In terms of structural design, protective plates are added around the motor.
One of the functions is to prevent the long-term operation of the motor from scalding the operator or adversely affecting other objects. The second function is to prevent heavy objects from falling and smashing the motor or small objects from falling into the motor;
The third function is to play the role of noise reduction
♦ Anti-static interface and hose
The dust-cleaning hoses and joints are made of anti-static material, and the conductivity is in accordance with DIN53482 standard, and the surface resistance is less than 106Ω.
