Cleanroom vacuum for wet and dry recovery
The Tiger-Vac CR-1300WD is a cleanroom vacuum for combined wet and dry recovery, developed for pharmaceutical manufacturing, semiconductor production, and microelectronics. Built in electropolished AISI 316 stainless steel, it meets the requirements for ISO Class 4 cleanrooms as defined in ISO 14644-1. The integrated stainless steel float system automatically shuts off liquid ingress before it reaches the motors, enabling reliable operation in both recovery modes. Two downstream ULPA U15 filters at the working air and cooling air exhausts ensure that all discharged air meets cleanroom standards, and each unit is individually aerosol-leak tested before leaving the factory.
The float system — the heart of wet recovery
The float (liquid cut-off) is machined in stainless steel and acts as a mechanical valve: when the liquid level in the recovery tank reaches a set point, the float rises and closes the suction inlet before any liquid can reach the filter housing or motors. The float assembly is fully detachable for easy dismantling and cleaning, and it is autoclavable to 121 °C. Recovered liquids collect in the 38-litre stainless steel tank, and a bottle of defoaming liquid is included for handling foam-producing substances.
Multi-stage filtration
The CR-1300WD uses a multi-stage filtration system. During dry recovery, collected material first passes through a synthetic disposable filter bag (19 L, Class M, IEC 60335-2-69) and then through a polyester cloth filter before leaving the motor chamber. The two downstream ULPA U15 filters then clean both the working air and the cooling air from the 2-stage bypass motor, so that all discharged air — regardless of flow path — is filtered to ULPA standard with an efficiency of 99.999 % at 0.12 µm and 99.9995 % at 0.18 µm (MPPS, IEST-RP-CC001). A filter blockage indicator light signals when the collection bag is full.
During wet recovery, the disposable bag and cloth filter are removed from the airflow path, and the float takes over protection of the filter housing and motors. The two ULPA exhaust filters remain active throughout.
Materials and surface finish
The entire vacuum — filter housing, recovery tank, frame, and wheels — is manufactured in AISI 316 stainless steel with an electropolished finish. Electropolishing removes surface contamination and micro-roughness that might otherwise trap particulate contamination, creating a smooth, easy-to-clean surface. The recovery tank and white nylon wheels are autoclavable to 121 °C. Static-conductive grey wheels (non-autoclavable) are available on request. Static resistance is measured at below 10 Ω.

Frequently asked questions
-
The CR-1300D is a dry-only vacuum, while the CR-1300WD is fitted with an internal stainless steel float kit that enables wet liquid recovery as well as dry dust collection. The float automatically closes the suction inlet when the liquid level reaches a critical point, protecting the motor and filters. Both models use a 2-stage bypass motor and dual ULPA U15 exhaust filters. The CR-1300D additionally offers a brushless motor option (BLSD), which is not available on the WD version.
-
The CR-1300WD is designed for collecting water-based liquids and spills in pharmaceutical and industrial cleanrooms. A bottle of defoaming liquid is included for foam-producing substances. The vacuum is not intended for flammable solvents or corrosive chemicals without prior assessment — contact Particulair for evaluation of specific liquid types.
-
Yes. The float assembly (liquid cut-off, part 212710) is made of stainless steel and can be autoclaved to 121 °C. It is fully detachable, so it can be dismantled, cleaned, and autoclaved independently of the rest of the machine. The recovery tank and white nylon wheels can likewise be autoclaved to 121 °C.
-
The two downstream ULPA U15 exhaust filters are active during both dry and wet recovery. The float protects the filter housing and motors from liquid by blocking the suction inlet when the tank is full. The ULPA filters continuously clean all air leaving the machine, maintaining cleanroom air quality regardless of recovery mode.
-
Yes. The CR-1300WD is documented as compatible with ISO Class 4 as defined in ISO 14644-1 (equivalent to Class 10 in FED STD 209E). Compatibility depends on the correct filter configuration — bypass motor with two downstream ULPA U15 filters — ensuring that neither the working air nor the cooling air contaminates the cleanroom atmosphere.
-
Every CR-1300WD unit undergoes an individual aerosol leak test at the factory before leaving the production line. The test verifies that there are no leaks in the filter housing or around the ULPA filters, and that the complete filtration system delivers the specified cleaning efficiency. This test provides relevant documentation for GMP validation processes.
-
For pharmaceutical cleanrooms, Kit #3 (323604) is typically recommended — it includes an autoclavable EPDM hose, stainless steel wands, and stainless steel floor tools. Kit #2 (323602) is the right choice where ESD safety is required. Standard Kit #1 (323306WD) covers general wet and dry handling without autoclave requirements.
