High-Volume Compressed Air Systems
In facilities with continuous-duty compressors like the Atlas Copco GA series, the SPM-SEP-1122 handles a flow of 348 m³/h, ensuring efficient separation of contaminants without restricting air supply. This maintains productivity in manufacturing or processing lines.
Moisture-Sensitive Pneumatic Tools
For workshops using pneumatic tools that require dry, clean air, this separator's 3 µm borosilicate glass fibre media captures fine particles and water droplets, extending tool life and reducing maintenance downtime.
Inventory Consolidation for Multi-Brand Fleets
Service centres supporting various compressor brands can stock the SPM-SEP-1122 as a universal replacement, simplifying inventory management while covering cross-references from Air Supply Co, Apureda, and many others.
Harsh Industrial Environments
In dusty or oily settings, the out-in flow design and durable gasket material provide reliable sealing and filtration, preventing bypass and protecting downstream equipment from contamination.
