Depureco PUMA 25 ACD
- Heavy industry with three-shift duty and high dust volumes
- Foundries and forges with continuous fine sand and metal dust
- Military and police shooting ranges with high lead-collection demands
- Metalworking houses with plasma, laser and water cutting
- Powder-metallurgy plants with sintered powder and fine dust
- IEC 60335-2-69 Annex AA (ACD)
- Low Voltage Directive 2014/35/EU
- EMC Directive 2014/30/EU
Depureco PUMA 25 ACD
The Depureco PUMA 25 ACD is the top of the PUMA range without HD reinforcement: 18.5 kW motor with 1380 m3/h airflow -- the highest in the range -- and 320 mbar vacuum. It is sized for the most heavily loaded process installations, where 1380 m3/h must be pulled through a larger suction manifold or a long cyclone channel. ACD certification per IEC 60335-2-69 Annex AA means the internal construction is treated as Zone 20 despite the non-ATEX-classified environment outside.

Questions and answers
Why is the Depureco PUMA 25 ACD a better choice than a standard industrial vacuum?
Because heavy industry and three-shift duty require a vacuum built to hold up for years in 24/7 operation without breakdown. The PUMA range has a reinforced frame, tangential cyclone inlet that preserves cyclone effect throughout filter life, and a drivetrain sized for continuous heavy load. The ACD certification per IEC 60335-2-69 Annex AA keeps the internal Zone 20 capacity intact.
Why this specific motor and phase configuration?
A three-phase side-channel blower at 7.5-18.5 kW is the only motor configuration that can handle the air quantities and vacuum levels heavy industry demands. The PUMA range offers different calibrations (P for flow, S for suction), so you match exactly your plant's profile. The 175 L container with tangential cyclone inlet ensures coarse dust does not burden the filter.
What types of dust is the Depureco PUMA 25 ACD actually intended for?
Heavy industrial dust in production volumes: fine foundry sand, magnetite dust, metal swarf and slag particles from plasma cutting, powder-metallurgy fractions, shooting-range lead dust, fine metal particles from light-metal rolling. For smaller volumes choose the TX range; for reactive metal dust choose the INERT models.
What is the difference between ACD and ATEX?
ACD is the certification for combustible dust in non-ATEX-classified industrial plants. Most steelworks, foundries and powder-metallurgy plants are not formally ATEX-classified even though the dust is combustible -- because the duty or dust concentration does not reach the classification threshold. ATEX is for formally classified zones per 2014/34/EU.
Which filter is fitted as standard, and can I upgrade to HEPA?
The standard is an antistatic polyester star filter class M at 45000 cm2 with relief valve and vacuum remote control. Options are HEPA H14 for class H plus Longopac collection for hygienic emptying without dust exposure. The PUMA range is prepared for compressed-air cleaning retrofit so filter maintenance can be automated.
How mobile or stationary is it in practice?
The Depureco PUMA 25 ACD weighs 370 kg and measures 850 x 1550 x 1980 mm -- a heavy stationary production vacuum with wheels for service relocation out of the hall at maintenance. It is placed fixed at a production station or in a central collection room with permanent hose routing. Noise level is 74 dB(A) at 1 metre.
