Our Activents are a fan‑driven anaesthetic waste‑gas exhaust system designed to safely remove all anaesthetic waste gases - including nitrous oxide - from the operating environment. Unlike Fluosorbers, which can present bacterial hazards, Activent provides active, reliable extraction while incorporating built‑in safety features to prevent both positive and negative pressure at the patient end. Typically wall‑mounted beside the anaesthetic workstation, it ensures a clean, compliant and efficient scavenging solution.

Product Features

• Removes all anaesthetic waste gases, including nitrous oxide
• Safer alternative to Fluosorbers, which carry bacterial contamination risks
• Designed for wall mounting beside the anaesthetic workstation
• Built‑in fixed 3‑litre reservoir
• Four top‑mounted inlet vents provide an open‑to‑atmosphere AIR‑BREAK
  • Prevents positive or negative pressure at the patient's end
  • Prevents gas spillover into the work environment
• Draws approx. 8 L/min of room air, mixing it with waste gases delivered via:
  • Standard 30 mm connectors
  • 22 mm flexible scavenging tubing (included)
• Actively propels waste gases to the disposal point up to 15 metres away
• Illuminated ON/OFF rocker switch with red power indicator
• Green light indicates fan operation (near‑silent running)

Activent Solo

• Single‑station, fan‑driven waste‑gas exhaust system
• Removes all anaesthetic waste gases and vapours from the operating suite
• Typically mounted adjacent to the anaesthetic workstation
• Installation can be carried out by a competent handyman

Activent Multi

• Includes a one‑way valve allowing multiple Activent units to be connected to a single external exhaust pipe
• Simplifies installation in multi‑room or multi‑machine practices
• Still requires one Activent per anaesthetic machine
• Top end includes AIR‑BREAK with four inlet holes
• Draws approx. 8 L/min of air to mix and propel waste gases
• Push‑button ON/OFF with power indicator and green fan‑running LED
• Recommended external termination via 22 mm tee‑piece
• Effective performance depends on local factors:
  • Length of tubing
  • Internal diameter
  • Smooth‑bore vs. convoluted pipework
  • Number of 90° bends

Regulatory Note

RCVS Practice Standards (section 5.12, paragraph 4):
“If a sophisticated active scavenging system is in operation, it must be serviced annually. A test certificate must be available and is an acceptable alternative to personal dosimetry.”

Cost Efficiency

Activents can pay for themselves in as little as 12 months.

Example comparison:

• Annual use of 12 Fluosorbers at £24 each = £288 per year
• Activent eliminates ongoing absorbent purchases

What’s Included

• 22 mm–22 mm straight connector
• 22 mm–30 mm connector
• Scavenging tubing for APL valve → Activent
• Wall‑mounting ‘V’ plate and bracket
• AC to adjustable DC Power Supply Unit
• Installation Starter Kit, providing:
  • Tubing and connectors to route exhaust upward
  • Right‑angled connector
  • Wall penetration (22 mm hole)
  • External tee‑piece termination

The system may be extended up to 15 metres using standard domestic 21.5 mm overflow tubing, available from common DIY retailers.
