About Delfin Industrial
Industrial-Grade Dust Extraction & Vacuum Solutions
Delfin Industrial Corporation, founded in Turin, Italy in 2000 by Antonino Siclari, manufactures over 140 distinct industrial vacuum cleaner models engineered for mission-critical dust capture in manufacturing, pharmaceutical, food processing, and chemical environments. Each unit is hand-assembled and individually tested to meet ISO 13849-1 machinery safety and customer-specific dust-handling certifications, from OSHA silica standards in metalworking to ATEX Class I/II explosive-atmosphere compliance in grain mills and chemical plants.
Delfin's product portfolio spans three-phase continuous-duty models rated for 24/7 operation without maintenance intervals (featuring lobe-pump vacuum generation and large-capacity 200+ liter collection tanks with auto-dump systems), single-phase portable models for light-duty shop cleanup and on-site wood dust collection, and specialized pharmaceutical vacuum cleaners rated for handling API (Active Pharmaceutical Ingredient) and HPAPI (Highly Potent API) dusts across OEB1–OEB5 operator exposure bands. Heavy-duty models feature multi-stage lobe pump systems, advanced antistatic polyester Class M star filters, and HEPA H14 secondary filters capturing 99.995% of sub-0.18 micron particles.
Explosion-proof vacuum lines (AIR, DG KW4 D1) are ATEX Class I and II, Division 1 & 2 certified for hazardous atmospheres: conductive collection tanks, spark detection with automatic shutdown, and intrinsically safe motor designs enable safe operation in grain silos, chemical spray-dry facilities, and metal powder processing areas. Every Delfin filter is individually performance-tested post-manufacture; the H14 HEPA cartridges are serialized and come with third-party certification documentation proving actual filtration efficiency before shipment.
Core markets include automotive manufacturing (weld-fume and cutting-oil mist collection), woodworking and aerospace composite shops (fine dust and fiber extraction), chemical API production (containment-rated systems with Bag-In/Bag-Out cartridge loading), pharmaceutical filling lines (Class B ISO 14644 cleanroom-compatible units), and food facilities (stainless-steel models for wet/dry conditions in bakeries and spice processing). Each application requires tailored suction capacity (CFM/m³/h), filter area, and containment features; Delfin's modular design allows swapping motors, pumps, and filter cartridges without complete unit replacement.

Frequently asked questions
What's the difference between Class M and HEPA H14 filtration?
Class M (antistatic polyester) filters capture 99% of particles down to 1 micron and are rated for toxic dusts like lead, asbestos, and crystalline silica; HEPA H14 (absolute filter) captures 99.995% of particles down to 0.18 microns and is required for pharmaceutical APIs, carcinogenic compounds, and food allergens. HEPA systems have higher pressure drop, requiring larger motors and higher operating cost; Class M is suitable for general manufacturing (welding, grinding) while HEPA is mandatory for health/safety-critical dust types.
Can I run a Delfin three-phase vacuum on single-phase power?
No—Delfin three-phase models require 3-phase 380–415V industrial power and cannot be converted to single-phase without a phase converter (which adds cost and reduces efficiency). For single-phase facilities, use Delfin's single-phase portable lines (e.g., HV103 backpack or DG KW4 D1 single-phase variants, 2–5 kW motors). Three-phase provides higher torque for lobe pumps and continuous-duty cycles; single-phase is limited to intermittent manual collection or lower-suction applications.
Are Delfin vacuums ATEX-certified, and what does ATEX Class I mean?
Yes, Delfin's AIR and DG KW4 lines carry ATEX Class I, Division 1 & 2 certification for Group IIA/IIB/IIC gases (hydrogen, methane, acetylene-equivalent hazard levels). ATEX Class I means flammable gases are present during normal operation (e.g., acetone vapor in paint shops, hydrogen in plating tanks); Class II is for combustible dust atmospheres. Every certified Delfin explosion-proof model has intrinsic spark detection, conductive collection tanks, and automatic motor shutdown if ignition-risk conditions are detected.
What's the expected filter cartridge lifespan and replacement cost?
Delfin HEPA H14 and Class M star filters typically last 1,000–2,000 operating hours (2–6 months at continuous duty) depending on dust loading; heavily contaminated environments (welding shops, sanding lines) require replacements every 4–8 weeks. Replacement cartridges cost $150–400 depending on model and filtration grade; Delfin sells serialized filter packs with third-party test certificates, and every filter is shipped with pressure-drop specifications so you can verify performance degradation.
Do Delfin vacuums require preventive maintenance beyond filter changes?
Three-phase continuous-duty models (DG series) have sealed lobe-pump systems rated for 2,000+ operating hours before bearing service; drain tanks at startup and after 500 hours of continuous operation to remove condensate and prevent bacterial growth in collection tanks. Check motor power draw monthly (increase signals filter loading); inspect hoses and tank seals quarterly. Single-phase portables require more frequent inspection of electrical cords and spark arrestors. Delfin provides maintenance manuals and spare parts kits for every model.
