Atlas Copco 1625775300, direct aftermarket replacement. This separator is an aftermarket separator designed as a direct replacement for models from Atlas Copco, Compair-Demag, Fai Filtri, Mann-Filter, and other leading brands. It utilises borosilicate micro glass fibre media with a 3 µm filtration rating to effectively remove oil and moisture from compressed air. With a burst pressure of 25 bar and a collapse pressure of 5 bar, this separator is built to handle demanding conditions. Its out-in flow direction and M25 female bottom thread ensure compatibility with specific Atlas Copco compressors including GA 5 VSD, GA 7 VSD, GA 11 VSD, and GA 15 VSD models. Offering a cost-effective aftermarket alternative, it delivers reliable performance without compromising on quality. Technical properties & cross references

Use cases & applications

High-Dust Industrial Environments
In settings like woodworking or cement plants where airborne particulates are high, this 3 µm separator captures fine contaminants before they reach downstream equipment. Its robust construction withstands pressure fluctuations common in such harsh conditions.

Continuous-Duty Manufacturing Lines
For production lines running 24/7, the separator's 120 m3/h flow capacity supports constant air demand without excessive pressure drop. The borosilicate media maintains efficiency over extended periods, reducing unplanned downtime.

Remote or Hard-to-Access Installations
When compressors are located in confined spaces or elevated platforms, the lightweight 0.97 kg design makes handling and replacement easier. Its compact 96 mm outer diameter fits tight spots without compromising performance.

Fleet Maintenance Standardisation
Operators managing multiple Atlas Copco VSD compressors can consolidate inventory with this single separator model. It fits GA 5, 7, 11, and 15 VSD units, simplifying stock management and reducing the risk of using the wrong part.

Frequently asked questions

How do I confirm this separator fits my compressor?

Check your compressor model against our verified list: Atlas Copco GA 5 VSD, GA 7 VSD, GA 11 VSD, and GA 15 VSD (serial numbers starting with CAI 700000). Also verify the thread is M25 female bottom and the total height is 211 mm.

What does the 3 µm filtration rating mean for my system?

The 3 µm rating indicates the separator captures particles as small as 3 microns, including oil aerosols and fine dust. This protects downstream components like dryers and valves from contamination.

What are the exact dimensions and thread type?

Outer diameter is 96 mm, total height is 211 mm. The thread is M25 female bottom with a 1.25 mm pitch. Flow direction is out-in, meaning air flows from the outside to the inside of the element.

Is this an OEM part or an aftermarket alternative?

This is a high-quality aftermarket replacement, not an OEM part. It is built to match the specifications of original separators from brands like Atlas Copco, Mann-Filter, and others, offering a cost-effective alternative.

How often should I replace this separator?

Replacement intervals depend on operating conditions and air quality. Typically, separators are changed during routine compressor maintenance, such as every 1-2 years or when pressure differential exceeds the manufacturer's recommendation.

What guarantees and shipping options do you offer?

We provide a 30-day money-back guarantee and a price-beat guarantee. Worldwide shipping with tracking is available; delivery times vary by location.

Our verdict

The spin on air oil separator for Atlas Copco GA 5, 7, 11 and 15 VSD compressors from serial CAI 700000: M25 x 1.25 female thread, 96 mm diameter, 3 micron borosilicate glass fibre media and 120 m3/h permissible flow. It crosses to Atlas Copco 2903775300, 1630404600 and 2202929400 and Mann LB 962/23.

Good for

  • Atlas Copco GA 5, 7, 11 and 15 VSD from serial CAI 700000
  • Replacing Atlas Copco 1625775300, 2903775300, 1630404600, 2202929400 or 2202929450
  • Compair 72296, Mann LB 962/23 and LB111028, Sotras DF 5075 and Oxfil SP.5075 users
  • Compressors showing oil carry over in the air line

Not the right choice for

  • GA VSD machines below serial CAI 700000 without checking the number on the old separator
  • Separators with a different thread; this one is M25 x 1.25
  • Anyone who needs an Atlas Copco branded part for a warranty claim

Key buying considerations

  • Thread: M25 x 1.25 mm, female, at the bottom
  • Outer diameter 96 mm; weight 0.97 kg
  • Media: borosilicate glass fibre, 3 micron; out to in flow; 120 m3/h permissible flow
  • Pressures: 25 bar burst, 5 bar element collapse

In real-world use

On small VSD compressors the spin on separator strips oil from the compressed air before it leaves the machine. A worn one lets oil carry over into the dryer and line filters; a blocked one raises the pressure drop and the power the motor draws. Change it on the service hours shown by the controller, oil the seal and tighten by hand.

How it compares

Same thread, diameter, media rating and flow as the separator under 1625775300 and its other Atlas Copco numbers. It is an aftermarket separator made in China (also listed as SPM-SEP-1066), not an Atlas Copco part.

Quick answers

Which compressors use 1625775300?
Atlas Copco GA 5, 7, 11 and 15 VSD from serial CAI 700000.

Is 2903775300 the same separator?
Yes. Atlas Copco 2903775300, 1630404600, 2202929400 and 2202929450 are listed as the same part, as are Mann LB 962/23 and Compair 72296.

What thread does it have?
M25 x 1.25 mm, female, at the bottom of the can.

Is it an Atlas Copco part?
