K330AO is the AO general-purpose grade of the domnick hunter® / Hankison® K-series line filters — the workhorse element for removing water and oil aerosols from compressed air, fitted in inline housings across plants of every size.
Our equivalent element is produced to the original OEM dimensions — outer diameter, length, end caps, seals and media — so it drops straight into the existing housing. K330 is one of the most requested sizes in the series and we stock tooling for fast shipment; the full K-series (K030–K620) and all grades (AO / AA / ACS / AR) are produced to order.

Same housing size, different media. Tell us your air quality target and we confirm the right grade.
| Grade | Function | Filtration Rating | Typical Residual Oil |
|---|---|---|---|
| AO — General purpose | Removes water & oil aerosols, solid particles | 1 µm | ≤ 5 mg/m³ |
| AA — High-efficiency | Deep oil-aerosol removal for critical points of use | 0.01 µm | ≤ 0.01 mg/m³ |
| ACS — Activated carbon | Adsorbs oil vapor & odor | Vapor removal | ≤ 0.003 mg/m³ |
| AR — Dust removal | Particle removal after dryers | 1 µm | — |
Values are typical industry reference figures for equivalent grades; exact performance per OEM specification is confirmed with the quotation. Sizes and flow ratings follow the original K-series numbering (K030 → K620).
Media and flow path engineered so pressure drop stays low across the element's life — energy you don't waste.
Diameter, length, end caps, threads and gaskets matched to the original — drops straight in, no rework.
Same media, same process, same inspection for samples and volume orders. Dimensional check on every batch.
K330AO and popular sizes run on stock tooling — fast sampling and short lead times, 7–15 working days.
Grades AO/AA/ACS/AR and sizes K030–K620 from one factory — mix models in one shipment.
Sealed bags, foam brackets and cartons that survive long sea freight. Full export documents provided.
