High Dust Environments
In facilities where airborne particulates are prevalent, such as woodworking or metal grinding shops, the SPM-SEP-1081 effectively removes contaminants from compressed air. This protects downstream equipment from abrasive wear and reduces maintenance frequency.
Continuous-Duty Operations
For manufacturing plants running compressors 24/7, this separator ensures consistent air quality. Its robust construction handles prolonged operation without performance degradation, minimising unplanned downtime.
Inventory Consolidation
Workshops servicing multiple Atlas Copco compressors can stock a single separator model for GA 30, GA 37, and GA 45 units. This simplifies inventory management and reduces the risk of stocking the wrong part.
Remote or Harsh Conditions
In outdoor or unheated compressor installations, the separator's durable build withstands temperature fluctuations and moisture. It maintains efficient separation even in challenging environments.
Check your compressor's model and serial number. This separator fits Atlas Copco GA 45, GA 37, GA 30 VSD, and GA 50 models from the serial number ranges listed on the product page. If your serial number falls outside those ranges, please contact our support team.
This is a separator, not a filter. It uses centrifugal action to remove liquid water and oil aerosols from compressed air. The efficiency depends on flow rate and pressure; typical removal efficiency is over 99% for particles down to 0.01 micron.
The critical dimensions are: body height 181 mm, outer diameter 167 mm, largest outer diameter 300 mm, and largest inner diameter 108 mm. Ensure your housing accommodates these sizes. The thread type is not specified; please check your existing separator's thread.
No, this is an aftermarket replacement built to match OEM specifications. It is a direct replacement for the original separator used in the listed Atlas Copco compressors. It offers similar performance at a lower cost.
Installation is similar to the original. Turn off the compressor and depressurise the system. Remove the old separator and clean the housing. Insert the new separator, ensuring it seats properly. Tighten the cover to the manufacturer's torque specifications. Refer to your compressor manual for detailed steps.
