Technical note
The Delfin DG VL 185 EX1/3D is designed for ATEX Zone 22 applications in industries handling combustible dust such as metal processing, pharmaceuticals and food production. Its Zone 20-rated interior allows safe dust collection directly into the filter and tank, while the Zone 22 external rating makes it safe to use in hazardous areas. All conductive parts are grounded to maintain a total resistance below 10⁶ Ω. Use only antistatic or conductive hoses and accessories to ensure full ATEX compliance.

FAQ
What does II 1/3D (Zone 20/22) mean?
It indicates very high protection inside the vacuum (Zone 20 – filter and tank) and enhanced protection outside (Zone 22).
Can it be used in chemical or food production?
Yes – all parts in contact with the material are made of AISI 304 and the filter media is antistatic and dust-tight.
How is the filter cleaned?
Via the automatic SELF CLEAN system – quick, safe and without compressed air.
Is it suitable for central vacuum systems?
Yes – the 18.5 kW motor and large filter capacity make it ideal for fixed pipework and multi-operator use.
