Selection Recommendations

When evaluating cyclone gas-water separators, procurement teams should prioritize:

1. Flow Matching: Select separator capacity 10-20% above peak compressor output to maintain efficiency during transient loads.
2. Pressure Drop Budget: Allocate ≤0.02 MPa pressure loss for cyclone stage to minimize compressor energy penalties.
3. Material Compatibility: Specify 316L stainless steel for corrosive gases (ammonia, chlorine) or food-contact applications.
4. Drain System: Automatic float drains reduce maintenance labor but require periodic valve inspection; zero-loss designs eliminate compressed air waste.
5. Integration Planning: Verify flange/thread compatibility with existing piping and downstream filtration stages (typically 1-3μm pre-filters follow cyclonic separation).
