Tiger-Vac CD-2600 EX CR (ARP) Z21 2D
ATEX Dust Zone 21 (Category 2D) industrial vacuum cleaner with Automatic Reverse Purge
The Tiger-Vac CD-2600 EX CR (ARP) Z21 2D is a stainless-steel ATEX-certified industrial vacuum cleaner developed for the safe recovery of combustible and conductive dusts in ATEX Dust Zone 21 environments, where explosive dust atmospheres may occur during normal operation. The model is part of the CD EX platform, which is fully third-party ATEX and IECEx certified by LCIE (0081), providing documented protection against ignition hazards around the motor, filter section and electrical enclosure.
Technical design and ARP filter system
The CD-2600 EX CR (ARP) Z21 2D is built as a vertically mounted, continuous-duty system with an explosion-proof 3-phase TEFC motor available in 2.2 kW or 4.0 kW versions. The 2.2 kW model delivers approx. 200 m³/h airflow and 2,540 mm H₂O vacuum, while the 4.0 kW model reaches up to 299 m³/h and 3,380 mm H₂O. The Automatic Reverse Purge (ARP) system continuously cleans the static-dissipative filter cartridge during operation, ensuring low pressure drop and consistent suction even during extended industrial use. The removable 36 L stainless-steel recovery tank allows safe and easy dust disposal with minimal operator exposure.
Safety, ATEX 2D and ESD control
The Z21 2D variant is designed for installations where documented protection in ATEX Dust Zone 21 (Category 2D) is required around the vacuum cleaner, without the need for gas-zone certification. The CD EX platform is tested according to relevant EN/IEC and ISO standards, including the EN 60079 and EN ISO 80079 series, and is fully ESD-safe with a total resistance below 10 Ω. The system safely handles combustible and conductive dusts with certified temperature limits, sealing integrity and proper grounding of all EX components.
Typical applications
The Tiger-Vac CD-2600 EX CR (ARP) Z21 2D is suitable for process-area cleaning and dust control in facilities handling combustible powders, where production machinery and dust sources are located in ATEX Dust Zone 21. Typical applications include pharmaceutical and biotechnology production, food and ingredient manufacturing, chemical plants, powder handling, granulation, mixing stations, tablet presses, sieving stations, silos and filling lines.
Need guidance on ATEX Dust Zone 21 (2D) compliance?
We help facilities choose the correct CD-2600 EX configuration, ARP filter system and ESD-safe accessories for compliant ATEX installations.
Technical note
The Z21 2D model is a dust-certified (D) variant of the CD-2600 EX CR (ARP) designed for ATEX Dust Zone 21 environments. It is based on the same CD EX platform as the other EX-certified models, where the motor enclosure, filter housing and electrical components are third-party certified, while hoses and nozzles follow ATEX/ESD standards without being individually certified. Correct grounding of hoses, pipes, vacuum body and operator is essential for safe operation.
FAQ
What is the difference between Z21 2D and Z22 3D?
Z21 2D is designed for Dust Zone 21 (Category 2D), where explosive dust atmospheres may occur during normal operation. Z22 3D is intended for Dust Zone 22, where explosive atmospheres are rare and short in duration.
When should I choose ARP instead of MRP?
ARP (Automatic Reverse Purge) is ideal for continuous-duty applications with high dust load, as it cleans the filter automatically and maintains stable suction. MRP (Manual Reverse Purge) is typically for intermittent or lighter-duty applications.
Is the vacuum suitable for pharmaceutical or hygienic environments?
Yes — the CD EX series is built from AISI 304/316 stainless steel and can be fitted with HEPA or ULPA final filters, making it suitable for GMP environments with ATEX Dust Zone 21 requirements.
What types of dust can the unit handle?
Combustible dusts, conductive powders, organic ingredients, pharmaceutical powders, food ingredients, chemical dusts, plastic granulates and other fine particulate materials.
