Product Details
High-Capacity 2 Stage Screw Compressor
,Mining Air Compressor High-Pressure
,Two-Stage Compression Air Pump
The AIRERA AGCD-355D II B VP screw air compressor is an ultra-high-capacity, heavy-duty technical marvel specifically engineered for mega-scale mining excavations and heavy engineering operations. Seamlessly integrating an industry-leading high-pressure two-stage compression airend with a high-capacity smart VSD system, this model delivers a continuous, powerful supply of constant-pressure compressed air even under extreme environments characterized by heavy mining dust, power grid fluctuations, and non-stop heavy workloads. Its reinforced, integrated, fully-enclosed chassis serves as a premium barrier against vibrations, explosions, and high temperatures, completely replacing inefficient legacy pumps prone to frequent breakdowns in harsh conditions to serve as a rigid core backbone for modern mining enterprises to safeguard 24/7 continuous production and maximize industrial asset value.
-
Silent centrifugal fan
Adopts the advanced centrifugal fan, which has large cooling air volume, low noise, stable and uniform air pressure, which makes full use of the heat dissipation area of the cooler, and greatly reduces the noise of the air compressor by 6-8dB.
-
Noise reduction sheet metal design
Multiple noise reduction designs, calculated according to noise science, with special flame-retardant and sound-absorbing cotton inside to reduce unit noise.
- Independent air intake system
Independent air intake ensures that the intake air temperature is equal to the ambient temperature. Large-capacity air filter is used to achieve better filtering effect, lower intake pressure loss, and energy saving and high efficiency. Maintenance and replacement are more convenient.

This heavy-duty model splits the extremely high-output high-pressure compression task into two separate stages, drastically lowering the pressure ratio per stage to fundamentally eliminate internal air backflow and severe thermal energy losses common under high-pressure operations. Relying on a smart VSD regulation grid designed specifically for heavy mining applications, the unit perfectly matches the high-frequency, large-flow air pulses of drilling rigs, ensuring discharge pressure remains rock-solid and constant to safeguard the high-efficiency continuous operations of mega-mine excavation lines 24/7 with surging power.
This equipment introduces an advanced heavy-duty smart VSD control network, capturing severe fluctuations in actual mining operational loads within milliseconds to adjust motor power dynamically, completely smashing the staggering power waste caused by the frequent idling of conventional mining pumps during non-drilling periods. Along with the exceptionally low rotational speed and ultra-light main shaft axial stress brought by two-stage compression technology, wear on core drive components is drastically reduced, which not only grants fixed assets an extremely long service life but also helps financial departments significantly drive down the comprehensive operational cost per ton of ore by minimizing routine maintenance frequency.
