Tiger-Vac CD/EUR-50L EX DT (MRP) 1/2GD

ATEX 1/2GD industrial vacuum for Zones 1, 2, 21 and 22 with internal Zone 20 protection

The Tiger-Vac CD/EUR-50L EX DT (MRP) 1/2GD is a fully ATEX- and IECEx-certified industrial vacuum cleaner designed for the safe recovery of combustible, conductive and metallic dusts as well as flammable gases and vapours. Classified as II 1/2GD, it provides full internal Zone 20 protection (1D/1G) and external Zone 1/21 and Zone 2/22 protection (2GD). The system includes an efficient MRP – Manual Reverse Purge filter cleaning mechanism, a static dissipative reverse-purge cartridge, a U15 ULPA final filter and a robust SS304 stainless-steel construction.

• ATEX category II 1/2GD – internal Zone 20/0 and external Zone 1/21/22.
• IECEx certified (IECEx LCI 10.0040X).
• U15 ULPA final filter included: 99.999% @ 0.12 μm.
• MRP filter cleaning – manual reverse purge without compressed air.
• Static-dissipative filter cartridge and components (<10 Ω).
• 4.0 kW TEFC explosion-proof/dust ignition-proof motor for continuous duty.
• 50 L SS304 detachable recovery tank (DT), compatible with poly liners.
• IP65 dust-tight housing and ISO Class 4 cleanroom compatibility.

Certification & safety

According to ATEX certificate LCIE 03 ATEX 6295 X, the vacuum is certified for use in explosive atmospheres involving both gases and dusts. Internal classification is Ex h IIC T6 Ga and Ex h IIIC T50°C Da, providing the highest protection inside the filter chamber and tank. External classification is Ex db h IIB T4 Gb and Ex h tb IIIC T135°C Db IP65, allowing installation in Zone 1, Zone 2, Zone 21 and Zone 22.

• Less than 10 Ω resistivity – full ESD protection.
• ULPA leak-tested according to EN 1822 and factory aerosol testing.
• Approved for both GAS (G) and DUST (D) hazardous areas.

Construction & performance

The MRP system uses an internal aluminised, static-dissipative spunbond cartridge that is cleaned manually via a reverse purge action, without the need for compressed air. Combined with a stainless-steel 304 construction and ULPA U15 filtration, the vacuum is ideal for high-risk environments where explosive gases and dusts may coexist.

• Airflow: 299 m³/h
• Vacuum: 3,380 mm H₂O
• VRV setting: 2,030 mm H₂O
• Sound level: 75 dB(A)
• Suction inlet: Ø63.5 mm

Applications

This 1/2GD model is designed for environments where explosive gas and dust atmospheres may be present simultaneously, and where maximum internal protection combined with certified external zone compliance is required:

• Pharma & biotech: ULPA U15, SS304, ISO Class 4.
• Additive manufacturing: conductive and metallic powders.
• Food production: flour, sugar, starch and fine powders.
• Chemical industry: combustible vapours + combustible dust.
• Process industries: suitable for Zone 1/2/21/22.

Technical note

In ATEX 1/2GD applications, correct bonding and grounding of hoses, tools, piping and operator workflow is mandatory according to TRGS 727, EN 1127-1 and NFPA 77. Although the vacuum is static-dissipative (<10 Ω), safe operation depends on proper grounding of the entire installation and the use of EX-rated accessories.
