View system integration details
This page explains how Pre-Filter is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A filtration component that removes larger particles and contaminants from incoming air before it enters the main filtration stages of a Sterile Air Generation System.
Technical details and manufacturing context for Pre-Filter
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Filtration Rating | 1–5 μm | Removes particles >5 μm; finer rating increases pressure drop.ISO 16889 |
| Filtration Efficiency | 99.9 % | For particles ≥5 μm; efficiency per ISO 16889.ISO 16889 |
| Operating Pressure | 1.0–1.6 MPa | |
| Maximum Pressure | 2.5 MPa | Exceeding may damage filter element. |
| Operating Temperature | 10–80 °C | Outside range may affect seal integrity.ISO 8573-1 |
| Maximum Temperature | 120 °C | Short-term peak; prolonged exposure degrades media.ISO 8573-1 |
| Flow Capacity | 100–1000 m³/h | At 0.1 MPa pressure drop; higher flow increases ΔP.ISO 8573-1 |
| Pressure Drop | ≤0.05 MPa | At rated flow; replace element when ΔP exceeds 0.07 MPa.ISO 3966 |
| Housing Material | 304 SS | 316L optional for corrosive environments.ASTM A240 |
| Filter Media | PP — | Polypropylene; PTFE membrane available for high temp.ISO 16889 |
| Connection Size | DN25–DN100 mm | Flanged or threaded; specify upon order.ISO 1127 |
| Weight | 5–50 kg | Depends on housing size and material. |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The Pre-Filter captures larger airborne particles such as dust, lint, and pollen before they reach finer filtration stages, protecting downstream filters and maintaining system efficiency.
The filtration rating is 1–5 μm per ISO 16889, with a filtration efficiency of 99.9% for particles ≥5 μm. These values are reference ranges and must be confirmed for the specific model.
Operating pressure is 1.0–1.6 MPa (max 2.5 MPa), and operating temperature is 10–80°C (max 120°C). Exceeding these limits may damage the filter element or affect seal integrity.
Replace the element when the pressure drop exceeds 0.07 MPa at rated flow. Regular monitoring of pressure drop is recommended to ensure optimal performance.
