Delfin SEP.DC-011
Cyclone and H14 filter unit for OEB 4 containment at process equipment — no side channel blower. Same filtration chain as the PHARMA 40.40 DC: cyclone ≥98 %, H14 absolute filter (20,500 cm²), crimp bag and magnehelic as standard. Requires an external CV vacuum unit.
- Integrated cyclone retains up to 98 % of powder before the H14 filter
- H14 absolute filter (20,500 cm²) — 99.995 % MPPS — included as standard
- Crimp bag (containment bag) and BIBO disposal as standard
- Magnehelic filter pressure indicator and capacity sensor (24 VDC) as standard
- No integrated motor — vacuum source provided by external CV unit in technical room
- Identical filtration configuration to the PHARMA 40.40 DC — WIP, Photohelic and ATEX options available
What is the Delfin SEP.DC-011?
The SEP.DC-011 is the motorless version of Delfin's PHARMA 40 DC platform. It combines the cyclone separator, H14 absolute filter, crimp bag collection system and magnehelic indicator in a single compact unit — identical to the PHARMA 40.40 DC — but without the integrated side channel blower. The vacuum source is instead provided by an external CV unit located in a technical room. It is the natural choice for installations where the vacuum supply is already centralised, or where motor noise needs to be kept out of the production area.
Filter pressure is monitored via the included magnehelic indicator, and the capacity sensor (24 VDC) signals when the collection container is full. The crimp bag's BIBO disposal ensures the operator never contacts the collected material. Optional accessories including WIP (Wash in Place), Photohelic indicator and ATEX Cat. 2GD follow the same programme as the PHARMA 40.40 DC.
The filtration chain in detail
The dust-laden process air enters the cyclone, where centrifugal force separates up to 98 % of the powder from the airstream and collects it in the crimp bag. The remaining air fraction then passes through the H14 absolute filter with a surface area of 20,500 cm² and a filtration efficiency of 99.995 % measured by the MPPS method. The magnehelic indicator provides continuous visual monitoring of the filter condition.
Filter replacement is carried out using the BIBO system (Bag-in Bag-out): the used filter is encapsulated in a sterile single-use bag before it is removed from the filter housing, ensuring the operator never contacts the contaminated material. When the capacity sensor signals a full container, the collection bag is crimped and sealed before emptying — again without operator contact with the collected powder.
