Use cases & applications
Continuous Production Environments
In manufacturing facilities that run compressors 24/7, consistent oil separation prevents air line contamination and costly production halts. This separator delivers dependable performance over long duty cycles, reducing unplanned maintenance stops.
High-Contamination Worksites
On construction sites or in dusty workshops, airborne particulates push compressor components to their limit. The robust construction of this separator maintains clean compressed air under harsh conditions, extending the life of the compressor and downstream tools.
Scheduled Maintenance Programs
During routine compressor servicing, fitting a fresh aftermarket separator ensures each interval starts with reliable componentry. Using this separator simplifies servicing routines and helps maintain consistent performance between overhauls.
Mixed-Fleet Servicing
Workshops maintaining compressors from Alup, Atlas Copco or other brands can stock this single separator to cover multiple machines. Consolidating inventory around one SKU reduces complexity and ensures the right part is on hand for a range of equipment.
Frequently asked questions
Will this separator fit my Alup ALLEGRO 110 compressor?
Yes, as long as your ALLEGRO 110 has a serial number from API170000 onwards. It also directly fits the Alup LARGO 110 from the same serial number range. This separator is a precise dimensional match for the OEM element used in those machines.
What is the filtration efficiency or micron rating of this separator?
This aftermarket separator replicates the oil coalescing performance of the original Alup and Atlas Copco elements. While exact efficiency figures are not published by the manufacturer, its construction is designed to deliver equivalent oil separation to the OEM part it replaces.
What are the physical dimensions, and is any modification needed to install it?
The separator stands 374 mm tall, has a main body diameter of 215 mm and a largest outer diameter of 342 mm. It weighs 5.12 kg. Installation is direct and requires no modifications. Always consult your compressor’s service manual and depressurise the system before replacement.
Is this a genuine Alup or Atlas Copco part?
