Double Stage Blower for Sewage Treatment Plants in Africa
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 Africa grid, climate and shipping route.
When a sewage treatment contractor in Africa asks Yash for a double stage blower, the quotation starts from the duty point and the 50 Hz supply — never from a catalogue number picked by guesswork. 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.
The Africa build is specified for 50 Hz / 380–415 V (3-phase) and ships CIF Mombasa / Durban / Lagos (or FOB Nhava Sheva) via Mombasa. Genset-ready builds for unstable grid power, robust filtration for dust and heat, and an in-house spares pipeline for remote sites. The recommended models are YEBL-DS-320V, YEBL-DS-520, YEBL-DS-900; each is dynamically balanced for the continuous duty sewage treatment runs, and each ships with test certificates on request.

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 Africa?
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 Mombasa / Durban / Lagos (or FOB Nhava Sheva).
How do you ship a Double Stage Blower to Africa?
Orders move CIF Mombasa / Durban / Lagos (or FOB Nhava Sheva), routed through Mombasa. 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.
