R546-Pro Gas Evacuation Apparatus
Active gas scavenging system from RWD that safely removes waste anesthetic gases from up to 5 mask stations simultaneously. Features a wide 8–60 LPM flow range, real-time LED display, and built-in canister weight monitoring with dual overweight alarms — eliminating guesswork around charcoal replacement and keeping vivarium and procedure rooms within occupational exposure limits.
What is the R546-Pro Gas Evacuation Apparatus?
The R546-Pro Gas Evacuation Apparatus (GEA) from RWD Life Science is engineered to actively and safely capture waste anesthetic gases generated during inhalation anesthesia in laboratory and veterinary settings. Built around a high-flow vacuum pump and an integrated activated charcoal canister, the system pulls expired and excess gases from up to five masks simultaneously and traps volatile agents before air is returned to the room — protecting personnel from chronic exposure and meeting modern occupational safety guidelines.
The upgraded R546-Pro is more compact and quieter than its predecessor, with a wider exhaust flow range (8–60 LPM) shown in real time on an LED display. Built-in online weighing of the charcoal canister (0–2000 g) and a two-level overweight alarm (990 g and 1010 g) take the guesswork out of canister replacement.
Key Features
- Wide flow rate (8–60 LPM): Real-time LED display lets researchers tune scavenging to the size of the experiment without venting hoods.
- Supports up to 5 masks: Powerful capture accommodates waste gas from 1 to 5 stations simultaneously — ideal for multi-animal stereotaxic suites.
- Adjustable per-station pull: Suction can be tuned independently across mask stations to match each procedure.
- Integrated charcoal canister with weight monitoring: Online weighing (0–2000 g) plus dual overweight alarms (990 g / 1010 g) signal exact canister-change timing.
- Compact, quiet, portable: Smaller footprint and low-noise design make it suitable for shared procedure rooms.
- No venting hood required: Self-contained system simplifies room layout and reduces facility costs.

Why active gas scavenging matters
Chronic exposure to waste anesthetic gases such as isoflurane and sevoflurane has been associated with headaches, fatigue and reproductive concerns among laboratory personnel. Regulatory bodies including NIOSH and OSHA recommend keeping ambient concentrations below 2 ppm for halogenated agents — a target that is essentially impossible to meet with passive scavenging alone.
Active scavenging systems such as the R546-Pro continuously draw waste gas through activated charcoal and prevent it from re-circulating in the room. The R546-Pro’s canister weighing system removes a common compliance gap — it is no longer up to the technician to remember when a canister is saturated.
Typical Use Cases
- Rodent stereotaxic surgery suites running multiple isoflurane stations.
- Vivarium imaging rooms (MRI, ultrasound, in-vivo optical) where animals are imaged under inhalation anesthesia.
- Veterinary clinics performing high-throughput dental, dermatology or soft-tissue procedures.
- Behavioral testing pipelines that require brief inhalation anesthesia for genotyping or implant checks.
