AIRERA 18.5HP Direct-Driven Oil-Injected Screw Compressor
The AIRERA 18.5HP Direct-Drive series represents the pinnacle of transmission efficiency. By eliminating belts and gears, we connect the motor directly to the airend, ensuring that every kilowatt of power is converted into high-pressure air. It is the ultimate "workhorse" for industries demanding zero-slip performance and minimal maintenance.
Key System Advantages
Drives and Electrics
The almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor. All electronic components are brand products from leading manufacturers.
Air End Block - Reliable Centerpiece - Design in Germany
The centerpiece of the compressor is the air end, which is constructed and manufactured with the most modern production methods in Germany. The optimal air end for your compressor can be used on a modulating basis. In frequency-controlled units, where the operating pressure changes, adjustments can also be made on the frequency controller to optimally adjust the speed of the compressor to the compressor performance.
Oil Circuit
The amount of oil in the units is determined to extend oil change intervals (depending on ambient conditions). An oil level sensor is integrated as standard and is read by the controller. All units in this series have a horizontal oil separation vessel where oil is separated from compressed air highly efficiently at low speeds.

Frequently Asked Questions
Q1: What is the main benefit of "Direct Drive" compared to "Belt Drive"?
Direct drive uses a high-precision coupling to connect the motor and airend 1:1. Unlike belt drives, there is zero energy loss from friction or slippage. It means 100% of the motor's power is transferred, increasing efficiency and eliminating the need to replace or tension belts.
Q2: How does the Direct-Drive system affect the noise level?
Direct drive is significantly quieter than belt or gear drives. By removing the high-frequency vibration of belts and ensuring perfect alignment via the coupling, the AIRERA 18.5HP runs smoothly with a low-decibel output, creating a better working environment.
Q3: Is maintenance more expensive for a Direct-Driven machine?
On the contrary, it is lower. You save on the cost of replacement belts and the labor time required for tensioning. The main maintenance involves standard oil and filter changes, which are made easy by AIRERA's accessible cabinet design.
