Tiger-Vac EXP1-35L (DT) RE HEPA (MRP) 2GD
ATEX Zone 1/21 and 2/22 vacuum cleaner for combustible and conductive dust
The Tiger-Vac EXP1-35L (DT) RE HEPA (MRP) is a third-party ATEX-certified industrial vacuum cleaner designed for the safe recovery of combustible and conductive dusts in both gas and dust classified zones (2GD). The unit is engineered for highly regulated environments such as pharmaceutical production, biotechnology, chemical industry and cleanrooms, where documented safety, filtration performance and ESD control are essential. All product-contact surfaces are manufactured from AISI 304 stainless steel and the entire system is ESD safe with components tested to less than 10 ohms.
- ATEX Marking: II 2GD Ex d IIA T3 Gb / Ex t IIIC T200°C Db IP6X (LCIE 03 ATEX 6297 – third-party certified).
- Cleanroom compatible down to ISO Class 4.
- HEPA H14 filter (99.995% MPPS) – aerosol leak tested before shipment.
- Static dissipative Reverse Purge filter cartridge for manual cleaning (MRP).
- AISI 304 stainless-steel construction and ESD-safe accessories included.
- Detachable Tank (DT) for safe, easy and dust-free disposal.
- Dry recovery only – ideal for very fine and sensitive powders.
Technical design
The system uses an explosion-proof motor housing (Ex d) with a sealed stainless-steel filtration chamber. The primary filter is a conductive aluminized spun-bond polyester cartridge cleaned manually using the Reverse Purge (MRP) system. The final filter stage is a H14 HEPA filter (99.995% at 0.3 microns) tested according to IEST-RP-CC001 and EN 1822. All included tools are static dissipative and suitable for the safe handling of combustible and conductive dust.
Safety and certification
- Third-party ATEX certification (notify body 0081 – LCIE).
- Gas classification: Ex d IIA T3 Gb.
- Dust classification: Ex t IIIC T200°C Db IP6X.
- Resistivity < 10 ohms on all conductive parts.
- Complies with EN 17348 (Combustible Dust Collection) and OSHA HEPA requirements.
- Static Dissipative (SD*) tool kit included.
Technical note
As a 2GD vacuum cleaner, the EXP1-35L (DT) RE HEPA (MRP) can be safely used in both gas and dust classified areas, offering high operational flexibility in pharmaceutical and chemical environments. The low surface temperature (T3) and full IP6X protection allow the safe recovery of very fine, combustible and conductive powders. The system is designed for process environments where standard equipment is not permitted and where documentation, traceability and cleanroom compatibility are critical.

FAQ
What does 2GD certification mean?
It indicates that the vacuum cleaner is approved for use in both gas zones (1/2) and dust zones (21/22), offering high flexibility in regulated environments.
Is the unit suitable for cleanrooms?
Yes – it is compatible with ISO Class 4 and built from stainless steel with ESD-safe materials.
How does the Reverse Purge system work?
A manual backflow mechanism sends air in the opposite direction through the filter cartridge, releasing dust without compressed air and without the risk of sparks.
How is the recovered material disposed of?
The detachable tank (DT) and static dissipative poly liners allow safe, controlled and dust-free disposal.
Is the HEPA filter tested?
Yes – every HEPA filter is aerosol leak tested before leaving the factory (H14/MPPS).
