Pharmaceutical Industry – Pneumatic Conveying Three-Lobe Roots Blower


At a chemical API manufacturing enterprise in Taizhou, Jiangsu Province, the existing blowers used in the powder‑sealed conveying process suffer from pressure fluctuations and seal leakage, which can lead to material blockages during API transfer and inconsistent batch yields. Additionally, these issues pose a risk of cross‑contamination within the cleanroom, thereby compromising the company’s GMP compliance management.
Following on-site operational assessments and a comparative evaluation of multiple solutions, the customer selected Nantong Rongheng Environmental’s custom‑designed pharmaceutical‑grade three‑lobed Roots blowers. The equipment features a leak‑proof sealing system and is equipped with food‑grade lubricants, meeting cleanroom production requirements and minimizing the risk of leakage‑induced contamination. Field measurements demonstrate significant improvements in pressure stability and continuous powder conveyance; batch yields have increased by 3.2% compared with pre‑modification levels, while operating noise remains at or below 65 dB(A), fully compliant with cleanroom environmental standards.
Since commissioning, the equipment has operated reliably, providing dependable support for the company’s continuous production and GMP‑compliant audits, and the customer has expressed strong approval of both product performance and service.
