Larger CSR separators use multi-part filters to make removal easier and safer during one-man servicing operations – even on the CSR 1000, 2000 and 3000

Brass thread inserts and twin accessible sample points demonstrate the careful design and build quality of STERLING separators

Optional floor stand for CSR150 & CSR450 raises the outlet in places where the  drop to the drain does not provide enough slope for correct flow

2000cfm & 3000cfm separators

CSR2000 and CSR3000 incorporate the CSEQ3 condensate splitter manifold. This ensures equal flow to the separator towers, getting the most out of the filters and preventing over-flows caused by overloaded units


A CSR2000 has two separators fed via a CSEQ3 manifold, while the CSR3000 comprises three separators fed through a CSEQ3
The manifold is available separately as a retro-fit device for any oil/water separator installation, or it can be used as a pressure relief chamber to protect separators in high pressure systems.

Thoughtful design as standard.
