Double Stage Blower for Sewage Treatment Plants in Asia
Double Stage Blower sized for continuous 24/7 fine-bubble diffused aeration — 200–2,000 m³/hr at 300–600 mbar — and built for the Asia grid, climate and shipping route.
A sewage treatment line runs on air, and in Asia the double stage blower that feeds it must be wound for 50 Hz, packed for the sea crossing, and backed by real spares. Get the sewage treatment sizing right and the rest is easy: the duty is continuous 24/7 fine-bubble diffused aeration, the window is 200–2,000 m³/hr / 300–600 mbar, and Pressure follows basin depth at roughly 100 mbar per metre; airflow follows the BOD load. Hold dissolved oxygen at 1.5–2.5 mg/L.
Because Asia is a 50 Hz market, no frequency conversion is needed — the motor is wound for 380–415 V (3-phase) directly, and short transit from India's west coast keeps lead time in days, priced for high-volume regional sourcing. For most sewage treatment projects in Asia the answer is one of YEBL-DS-320V, YEBL-DS-520, YEBL-DS-900 — confirm the duty and we quote the YEBL-DS-320V or its neighbour firm.

Double Stage Blower — the fit for sewage treatment
Two stacked impellers hold the 400–500 mbar-plus head that deeper 4–5 m municipal aeration basins demand against the water column.
| Model | Power | Flow (m³/hr) | Flow (CFM) | Vacuum (mbar) | Pressure (mbar) | Noise (dB) | Weight (kg) |
|---|---|---|---|---|---|---|---|
| YEBL-DS-320V | 7.5 HP | 320 | 188 | -440 | 500 | 73 | 70 |
| YEBL-DS-520 | 15.0 HP | 520 | 317 | -430 | 660 | 74 | 123 |
| YEBL-DS-900 | 15.0 HP | 900 | 529 | -280 | 370 | 74 | 110 |
Pressure follows basin depth at roughly 100 mbar per metre; airflow follows the BOD load. Hold dissolved oxygen at 1.5–2.5 mg/L. Indicative only — final selection depends on your exact duty point, altitude and air temperature.

FAQDouble Stage Blower for Sewage Treatment Plants — FAQs
Which Double Stage Blower model do I need for sewage treatment in Asia?
For a typical sewage treatment duty of 200–2,000 m³/hr at 300–600 mbar, start with YEBL-DS-320V and step through YEBL-DS-320V, YEBL-DS-520, YEBL-DS-900 as the load rises. Pressure follows basin depth at roughly 100 mbar per metre; airflow follows the BOD load. Hold dissolved oxygen at 1.5–2.5 mg/L. Send us your exact flow and pressure and an engineer confirms the model and quotes it CIF your SE Asian port (or FOB Nhava Sheva).
How do you ship a Double Stage Blower to Asia?
Orders move CIF your SE Asian port (or FOB Nhava Sheva), routed through your SE Asian port. Units are palletised and packed in seaworthy, ISPM-15 heat-treated wooden crates and declared under HS heading 8414. Commercial documents, certificate of origin and per-unit test certificates travel with the shipment on request; spares can follow by air freight.
