Advanced ventilator system for rodents

SAR-1000 Advanced Small Animal Ventilator

The SAR-1000 has a simple and intuitive interface, with direct setting of Tidal Volume, Rate, I/E Ratio, and much more. Features an automatic Sigh function and complete remote-control using supplied software. Includes everything needed for mouse or rat ventilation.

SAR-830/AP Small Animal Ventilator, Volume / Pressure cycled

SAR-830/AP Small Animal Ventilator

The SAR-830/AP is our classic ventilator for rodent-size animals.  Multi-animal setups (up to 5 animals per ventilator) are made easy by adding external valve assemblies. Compatible with anesthesia, and feature a built-in control interface for remote-control applications.

MR-compatible ventilator system for imaging applications

MRI-1 MRI-compatible Ventilator

The MRI-1 Ventilator is a small animal ventilator designed for use in MRI environments. The system comprises a main control unit and a remote pneumatically operated, non-magnetic breathing valve. The MRI-1 is compatible with anesthesia and has a built-in remote-control interface.

Cycle-triggered ventilation

AVS-1 Cycle-triggered Ventilator

The AVS-1 Advanced Ventilator System is the direct descendent of the classic CTP-930 Cycle-Triggered Ventilator, and features neural control, demand mode, and much more. Compatible with mice, rats, and larger animals.

Anesthesia for all CWE ventilators


CWE offers complete Isoflurane anesthesia kits for all of our ventilators. A simple system consists of an external flowmeter and vaporizer.
