Delfin PHARMA 40.40 DC
The Delfin PHARMA 40.40 DC is a stationary industrial vacuum for containment of highly potent APIs at tablet presses, blister machines and process equipment. With an integrated cyclonic pre-separator, H14 BIBO filtration and a sealed crimp-bag collection system as standard, it is rated for OEB 4 and OEB 5.
- Integrated cyclone retains up to 98 % of powder before the filter
- H14 absolute filter with BIBO system as standard — safe filter change without operator contact
- Crimp-bag (containment bag) as standard — BIBO principle during emptying
- Side channel blower 4 kW — designed for continuous 24/7 operation
- Suitable as dedicated machine vacuum (FETTE and similar) or centralised vacuum system
- Control panel for BMS signal output and operator HMI available to specification
What is the Delfin PHARMA 40.40 DC?
The PHARMA 40.40 DC is the closed-containment version of Delfin's PHARMA 40.40 platform. DC stands for Dust Containment — signalling that this vacuum does not merely collect powder but actively contains it throughout the entire chain: from the cyclonic pre-separator that retains at least 98 % of the powder before it ever reaches the filter, to the BIBO system that allows H14 filter changes without the operator touching the collected material, to the crimpable containment bag that seals all collected matter before it leaves the machine. All three barriers are standard equipment, not options.
The unit can be deployed as a dedicated machine vacuum alongside a single tablet press — such as FETTE and similar platforms — or integrated into a centralised vacuum system serving multiple process lines simultaneously. For demanding integration environments, a control panel with BMS signal output is available, and operator HMI panels can be configured to specification.
The drive unit is a side channel blower — an industrial turbine cooled independently of the process air that runs continuously around the clock without thermal limitations. The construction is in AISI 304 satin-finished steel with AISI 316 on all product-contact surfaces.
The three containment barriers as standard
The cyclonic pre-separator is mounted upstream of the filter and retains up to 98 % of the collected powder. This significantly extends filter service life and ensures that only a minimal residual fraction reaches the H14 filter. The cyclone can be fitted with a WIP (Wash in Place) function as an option, enabling in-situ cleaning of the separator and hopper.
The filtration system consists of an upstream H14 absolute filter with BIBO system (Bag-in Bag-out) and a downstream H14 absolute filter. The BIBO system allows the spent filter to be encapsulated in a sterile single-use bag during replacement, so the operator never directly handles the collected material. The filter housing is stainless steel with a BIBO support plate as an accessory (part no. SL.5907.0017).
The collection system is a crimpable containment bag placed inside the collection container before startup. When the container is full, the bag is crimped shut using a crimping tool — also following the BIBO principle, so the operator is not exposed to the collected material during emptying. The sealed contents can then be disposed of according to the facility's hazardous waste procedure.
