Description

ALUP EK 051522 Piston-Type Air Compressor Unit – 16 bar

The ALUP EK 051522 is a heavy-duty piston-type air compressor unit designed for reliable performance in high-pressure applications. Manufactured in 1993 by ALUP Kompressoren GmbH, the unit is CE-marked and equipped with a 350-liter air receiver and a rated pressure of 16 bar, making it suitable for medium to heavy industrial air systems.

This compressor operates within a wide temperature range from -10°C to +50°C and is powered by a robust 9.0 kW motor supplied by ABM Greiffenberger Antriebstechnik GmbH (Germany). The motor runs at 2850 RPM, operates at 380V/50Hz, and is designed for continuous-duty operation (S1) with IP54 protection and F-class insulation.

Lubrication guidelines specify the use of high-quality compressor oil conforming to DIN 51506, with initial oil changes at 30 and 100 operating hours, followed by a regular interval of every 500 hours.

This unit is suitable for stationary air supply in workshops, manufacturing plants, or utility rooms where durability and consistent performance are required.
