Depureco PUMA HD 30P ACD
The Depureco PUMA HD 30P ACD is the flow model in the HD range: 21.3 kW motor built for steelworks, foundries and powder metallurgy, with 1985 m3/h airflow at 220 mbar vacuum and a 110,000 cm2 antistatic polyester filter area. HD stands for heavy duty -- reinforced frame, 560 kg with integrated forklift inlets and a factory-fitted electric shaker. Sized for industries where a standard PUMA would wear out in a few months.
Applications

Questions and answers
Why is the Depureco PUMA HD 30P ACD a better choice than a standard industrial vacuum?
Because steelworks, foundries and powder metallurgy wear out ordinary PUMA models in a few months. The HD range has a reinforced frame over 560 kg, 110,000 cm2 antistatic polyester filter area, factory-fitted electric shaker and integrated forklift inlets -- a category-level different robustness. The ACD certification per IEC 60335-2-69 Annex AA preserves internal Zone 20 capacity under extreme operating conditions.
Why this specific motor and phase configuration?
A three-phase side-channel blower at 21.3-25.3 kW is the only motor configuration that can move the air quantities and handle the vacuum-demanding applications HD industry requires. The motor is overspecified for 24/7 duty with service intervals of several thousand hours, and the drivetrain is direct-coupled without drive belts requiring maintenance.
What types of dust is the Depureco PUMA HD 30P ACD actually intended for?
The heaviest combustible dust fractions: coarse foundry sand, magnetite dust, slag particles, fine aluminium and titanium dust from rolling and stamping processes, powder-metallurgy fine fractions, fine metal particles from plasma and laser cutting. The HD range is chosen where a standard PUMA is undersized and where INERT protection is not required (the dust is combustible but not reactive).
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 plants. Most steelworks and foundries are not formally ATEX-classified, but the dust is still combustible and equipment must be certified. ATEX is the 2014/34/EU Directive for formally classified zones.
Which filter is fitted as standard, and can I upgrade to HEPA?
The standard is an antistatic polyester star filter class M at 110000 cm2 with integrated electric shaker -- a mechanical cleaning function ensuring continuous filter area even in high-dust environments. Options are HEPA H14 and pulse cleaning systems (compressed-air based) for fully automated filter maintenance.
How mobile or stationary is it in practice?
The Depureco PUMA HD 30P ACD weighs 560 kg and measures 1050 x 1950 x 2300 mm -- an industrial HD vacuum with integrated forklift inlets for service relocation. It is placed fixed at a foundry, steelworks or powder-metallurgy plant and connected via permanent three-phase cable. Noise level is 78 dB(A) at 1 metre.
