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.
