What is the Tiger-Vac CWR MRAC?
The CWR MRAC series is Tiger-Vac's pharmaceutical wet and dry recovery vacuum for cleanroom environments, designed for applications where dust and liquids are accompanied by toxic fumes or vapours from organic solvents. The defining feature is the Middle Ring with Activated Carbon (MRAC) — an intermediate ring containing 8 kg of activated carbon pellets, mounted between the collection tank and the filter housing to adsorb vapours that would otherwise pass through the filtration system. The ring is an optional component, but the series is purpose-built around it.
The 5-stage filtration system consists of a synthetic disposable bag, a double cloth filter, and two ULPA U15 final filters — one for the working air and one for the motor cooling air. This means all air leaving the vacuum, including the air used to cool the motor, is filtered before being exhausted into the room. Each ULPA U15 filter retains at least 99.9995 % of all particles at MPPS and is individually aerosol tested before dispatch from the factory.
The vacuum is EMI/RFI shielded and electrically rated as static dissipating with a resistance below 10 ohm, making it suitable for use near sensitive electronic equipment and in environments with ESD control requirements. The unit is available with a stainless steel tank in two capacities (CWR-10: 28.4 L and CWR-15: 47.3 L), and the CWR-15 is also available with a polyethylene tank (POLY MRAC) as an alternative to stainless steel.

Options and upgrades
The activated carbon MRAC ring is the key optional feature of the series and must be specified at the time of order. Four carbon cartridge types are available depending on the chemical exposure in the production environment:
| Part no. | Carbon type and application |
|---|---|
| 212200B | Standard 3 mm activated carbon — general use |
| 212200C | Mersorb activated carbon — mercury vapours |
| 212200K | KOGC3/KINA3 carbon — chloride vapours |
| 212200L | A-3 carbon — arsine and phosphine vapours |
As an alternative to the ULPA filter in the MRAC configuration, an internal HEPA filter (part no. 211027B, 99.995 % at 0.3 µm) can be fitted where ULPA U15 over-specifies the application. The needle trap (part no. 215500) in electropolished stainless steel is a key option for environments handling needles, glass fragments and other sharps.
