- Continuous process duty in powder metallurgy and sintering
- Foundries with sand, mould and process dust
- Paper and cardboard production with fine cellulose dust
- Fixed grinding-machine stations with compressed-air-switched extraction
- CNC houses and milling centres with industrial extraction
- IEC 60335-2-69 Annex AA (ACD)
- Low Voltage Directive 2014/35/EU

Depureco TX 550S ACD
The Depureco TX 550S ACD is the suction variant of the TX 550 range: 5.5 kW motor calibrated to 440 mbar vacuum -- one of the highest in the TX range without HD reinforcement. Flow capacity at 330 m3/h is deliberately lower so the motor's energy is devoted to lifting heavy dust through long hoses. The model suits foundries with fine sand fractions, welding stations with metallic splatter and process plants with small inlets. IEC 60335-2-69 Annex AA preserves the Zone 20 capacity internally.
Applications
- Continuous process duty in powder metallurgy and sintering
- Foundries with sand, mould and process dust

Questions and answers
Why is the Depureco TX 550S ACD a better choice than a standard industrial vacuum?
Because production-line collection requires a vacuum that can run 24/7 without human supervision. The TX range is a side-channel blower with 100 L tangential cyclone container, designed to sit fixed in the line and collect continuously through a cyclone inlet. The ACD certification per IEC 60335-2-69 Annex AA preserves the internal Zone 20 capacity, so combustible dust does not become an ignition source for the production environment.
Why this specific motor and phase configuration?
A three-phase side-channel blower is the only motor configuration that can run continuously 24/7 in a production flow. The TX range offers different motor sizes and flow/suction calibrations, letting you match exactly the suction profile your production plant requires -- from 3 kW to 7.5 kW, from 160 mbar flow-biased up to 440 mbar suction-biased.
What types of dust is the Depureco TX 550S ACD actually intended for?
Continuous process dust in production-line quantities: fine foundry sand, metal swarf from CNC and laser-cutting lines, powder-metallurgy fractions, cellulose dust from paper and wood industry, fine aluminium and magnesium dust from light-metal machining. The TX range is used where collection is a fixed part of the production flow, not a mobile task.
What is the difference between ACD and ATEX?
ACD is the IEC 60335-2-69 Annex AA certification for combustible dust in non-ATEX-classified production halls. Most industrial plants are not formally ATEX-classified because dust concentration does not constantly exceed the classification threshold -- but a fine-dust ignition is still a realistic risk. ATEX is for formally classified zones per Directive 2014/34/EU and used in Zone 20/21/22.
Which filter is fitted as standard, and can I upgrade to HEPA?
The standard is an antistatic polyester star filter class M at 38000 cm2 with integrated relief valve. Options are SP (star-polyester with pulse cleaning) or PSC (polyester cartridge with compressed-air cleaning) plus HEPA H14 for class H. The compressed-air cleaning option is recommended at high dust volumes where manual filter cleaning would interrupt production.
How mobile or stationary is it in practice?
The Depureco TX 550S ACD is a stationary production-line vacuum at 155 kg -- on wheels and movable, but not intended for daily relocation. Placement is fixed at a production station with permanent cable and hose routing. Noise level is 76 dB(A) at 1 metre, matched to industrial background.
