Animal Ventilators

CWE, Inc. has been at the forefront of numerous innovations in small animal ventilation. Our advancements range from the foundational SAR-830 Series, offering volume and/or pressure-cycled models for routine small animal maintenance, to sophisticated computer-controlled models tailored for specialized applications. 

All CWE ventilators operate on the flow-time principle, ensuring consistent performance. This method employs a constant flow of gas, regulated into the animal for a predetermined time, resulting in a precise volume (flow x time = volume). This straightforward yet effective approach affords remarkable flexibility in setting ventilation parameters such as inspiration time and I/E ratio. Such customization is challenging or unfeasible with older mechanical piston-pump technology.

Furthermore, this design enhances the legendary reliability and durability of our ventilators. With only a pair of long-life solenoid valves as moving parts, our ventilators boast extended service life and unparalleled dependability.
