Delfin PHARMA 40.40 3D
ATEX Zone 22 H-Class vacuum cleaner for point extraction and pharmaceutical environments
The Delfin PHARMA 40.40 3D is a compact, quiet and hygienic H-Class industrial vacuum cleaner designed for the safe collection of fine and combustible dust in areas classified as Zone 22 (category 3D). It is used for on-board extraction from process machines in pharmaceutical, biotech and clinical applications where high filtration efficiency, low noise level and cleanroom compatibility are essential. The unit features a 4 kW side-channel blower providing increased airflow and stability for continuous operation. The filtration system includes an M-Class star filter and a HEPA H14 safety filter tested according to EN 1822-5 (MPPS method).

Technical design
The PHARMA 40.40 3D is designed for continuous duty and built entirely in AISI 304 stainless steel with welded and polished interior surfaces, ideal for pharmaceutical and cleanroom environments. The filtration section comprises an M-Class star filter (20 000 cm²) and a HEPA H14 final filter (20 500 cm²), ensuring maximum retention of fine and hazardous dust. The inlet connection is a Clamp Ø70 mm stainless-steel coupling. All components are antistatic and fully grounded according to EN 17348.
Options and system integration
The PHARMA 40.40 3D can be configured with a wide range of factory options depending on the process and cleanroom requirements. All parts are antistatic and manufactured in compliance with EN 17348 and GMP guidelines:
- FDA – FDA-certified antistatic filter
- XX / XX/IP / XXX – Filter chamber and frame in AISI 304 stainless steel (standard, polished or mirror finish)
- SB – Safe Bag system for safe dust collection and disposal
- FI.0469.0000 – Replacement bags for Safe Bag system
- TA.1115 / TA.1114 – Clamp 3″ coupling kits (Ø70 / Ø50 mm) in AISI 304
- H/OUT – Downstream HEPA H14 exhaust filter
- HX/IN – Upstream HEPA H14 BIBO system in stainless-steel housing
- BIBO H14 SPARE KIT – Replacement set (filter, nylon bag, gasket)
- SL.5907.0017 – Stainless-steel base plate for BIBO filter replacement
- MAGNEHELIC / PHOTOHELIC – Differential pressure gauges (manual / 24 V electronic, ATEX on request)
Cleanroom compatibility
In BIBO configuration (HX/IN + H/OUT + BIBO H14 KIT) and full stainless-steel execution, the PHARMA 40.40 3D can be used in ISO 5 – ISO 4 cleanrooms for local extraction of fine and hazardous dust without any risk of contamination during filter replacement. It meets the particle-tightness and emission requirements for the controlled production of active and sterile substances.
Containment and OEB level
When equipped with the BIBO system, Safe Bag and sealed filter chamber, the PHARMA 40.40 3D can be used in OEB 3–4 containment areas requiring high operator protection and controlled handling of active pharmaceutical ingredients (API). The closed design and antistatic components ensure complete containment during operation and maintenance.
Safety and certification
