VENTILATOR FOR WIDE RANGE OF ANIMALS

Our microprocessor controlled ventilator is suitable for use with animals
from mice to rabbits. The ventilator operates on the piston in cylinder
principle but is powered by a microstepping motor controlled by a
microprocessor. Such design assures ability of easy adjustment of
respiration frequency, speed of piston during each moment of the
respiratory cycle, delivered tidal volume and inspiratory/expiratory
ratio. The accuracy of air volume is assured in this system with virtually
leak-free electronic valves and graphite piston in a glass cylinder. No
lubricants which could contaminate the respiratory air are needed. The
ventilator features five interchangeable cylinders covering tidal volume
range from 0.08 to 50 ml and respiration frequency of 5 to 200 breaths per
minute. The inspiratory/expiratory timing ratio can be adjusted from 1:4
to 4:1. If you are interested in receiving more information please drop me
