VetEquip VaporGuard Activated Charcoal Adsorption Filter – Heavy-Duty Waste Anesthetic Gas Canister, High-Efficiency Charcoal Matrix, Saturated Mass Monitoring (MPN: 931401)

The VetEquip 931401 (commonly cataloged across veterinary research and surgical supply networks as 931401 / VetEquip VaporGuard) is an essential, high-capacity passive waste anesthetic gas (WAG) canister engineered to capture volatile halogenated anesthetic agents. Packed with high-grade activated carbon, this mobile canister absorbs halogenated inhalation gases—including Isoflurane, Sevoflurane, and Halothane—from the exhaust lines of veterinary anesthesia circuits. Designed for seamless, friction-fit integration with standard 1/2-inch and 19 mm scavenger tubing, the VaporGuard canister traps waste gas molecules before they escape into the surgical room atmosphere, protecting veterinary surgeons, technicians, and laboratory personnel from chronic exposure. Operating reliably across both passive gravity-feed loops and active vacuum-assisted scavenging circuits, it provides a safe, portable waste-gas management solution for animal research facilities and clinical operating rooms.

Technical Performance and Safety Features

• High-Density Activated Carbon Matrix: Packed with premium-grade, granular activated charcoal featuring an expansive internal surface area. This matrix binds volatile organic compounds and halogenated gases on contact, preventing hazardous gas recirculation into the workplace.

• Universal Port Connection Interface: Outfitted with a standardized top intake port that fits standard 1/2-inch ID and 19 mm anesthesia scavenging hoses, establishing a tight, leak-free seal without requiring special adapters or tools.

• Saturated Mass Monitoring Protocol: Designed for straightforward weight-based saturation tracking. Technicians simply weigh the canister before initial use and replace the filter once it gains a specific maximum weight threshold (typically 50 grams of absorbed gas mass above tare weight), eliminating guesswork.

• Versatile System Compatibility: Functions effectively in passive gravity-flow scavenger lines or as the primary absorption filter on active waste gas evacuation systems, maintaining low backpressure across small animal breathing circuits.

Product Specifications

• Max Absorption Capacity Threshold: Absorbs up to 50 grams of waste gas prior to mandatory filter retirement

• Physical Canister Profile: Cylindrical, high-impact polymer housing designed to sit upright on equipment carts or mount in scavenger brackets

Key Benefits and Applications

• Veterinary Surgical Suite Waste Scavenging: Protects clinical staff during rodent, small animal, and avian surgical procedures by filtering waste gas exhausted from non-rebreathing circuits and induction chambers.

• OSHA and NIOSH Compliance: Helps research institutions and veterinary hospitals adhere to workplace safety regulations regarding waste anesthetic gas exposure limits in unventilated spaces.

• Mobile Anesthesia Cart Setup: Eliminates the need for costly fixed wall-mounted ductwork, allowing portable anesthesia carts to be moved safely between surgical prep rooms, procedure suites, and recovery bays.
