VSD Air-Cooled 18.5kW Two-Stage Oil-Injected Air Compressor | Wide-Pressure Range (0.7–1.3 MPa) with Inverter Control, Low Noise, and Stable Operation
The AIRERA 18.5kW two-stage oil-injected screw air compressor is meticulously engineered for modern industrial production lines demanding high duty cycles and premium energy efficiency. By integrating industry-leading two-stage compression technology, the unit optimizes pressure ratios to significantly minimize internal backflow leakage, dramatically boosting volumetric efficiency. Equipped with a cutting-edge Variable Speed Drive (VSD) inverter control system, it delivers precise, digital pressure regulation across a wide range of 0.7–1.3 MPa, perfectly matching fluctuating factory air demands and eliminating idling energy waste to achieve overall power savings of over 30%. Featuring a fully enclosed, heavy-duty sound-dampening cabinet and an intelligent monitoring system, this compressor ensures stable, continuous 24/7 air supply while maintaining an ultra-low noise, eco-friendly workspace—making it the ultimate core power solution for lowering operational costs and increasing reliability.
-
Industry-leading air host
The air compression chamber is completely separated from the oil chamber. The air side adopts a non-abrasive sealing system with a spring-loaded metal ring, and the lubricating oil side adopts a non-abrasive sealing system with a copper labyrinth seal. The two do not contact;
-
Expanded filtering system design
Multiple air filter designs, more durable and stop much more particles outside, protect inlet system of compressor for long time working outdoor & indoor environment.
- 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.

The 18.5kW range is the core power workhorse for small to medium factories. Traditional single-stage compression suffers from severe gas backflow leakage at higher discharge pressures due to an excessive pressure ratio. AIRERA's two-stage compression divides the total pressure ratio across two stages with inter-cooling, drastically reducing internal leakage. At the same 18.5kW power input, its air output is 10%–15% higher than a standard single-stage compressor. This means you get more compressed air or complete the same work in less time, saving a massive amount on electricity bills over long-term operation.
First, two-stage compression features a lower pressure ratio per stage, leading to evenly balanced rotor loads and naturally fewer mechanical vibrations than single-stage units. Secondly, AIRERA utilizes a fully enclosed, heavy-duty sound-dampening cabinet design to block mechanical and airflow noise at the source. For stability, our optimized internal airflow and premium oil-injected cooling system ensure the equipment maintains ideal working temperatures, preventing high-temperature tripping even during 24/7 continuous high-intensity, heavy-duty operations in hot summer environments.
