KDS35 Small Animal Ventilator
Description & Features
The KDS35 is a volume controlled small animal/rodent respirator:
•Strong motor and motor speed control with LED (light emitting diode) read-out of rate
(stroke rate or breaths/min).
•Vertical slide valve that has no “O”-Rings or passive check valves and requires no
adjustments.
•Orientation allows for minimal system dead space and thus more precise tidal
volume delivery to the animal
The KDS35 is a positive volume ventilator intended to meet the respiratory requirements of
small laboratory animals weighing up to 5 kg (11 lb), covering rodents through rabbits.
This ventilator is furnished with two interchangeable piston/cylinder assemblies of 0.2 to
5.0 ml/breath (5 CC) and 1.5 to 30.0 ml/breath (30 CC). The smaller cylinder is factory
installed, and the larger one is supplied separately. The mechanical design features a linkage
that enables the piston to touch the end of the cylinder at each stroke regardless of the
volume. This assures that all the air/gas mixture taken into the ventilator is expelled
at each stroke.
A positive mechanical slide valve is actuated by a cam on the motor to synchronize inspira-
tion and expiration with the motion of the piston. Any NON-EXPLOSIVE gas/air mixture can
be used with the ventilator. Connection kit (78-0937) is suggested for this connection. A
three-way slide valve is attached to the mechanism plate at the end of the cylinder and actu-
ated by a cam on the motor.
This ventilator CANNOT BE USED IN AN EXPLOSIVE ATMOSPHERE OR WITH ANY EXPLO-
SIVE GASES SUCH AS ETHER OR CYCLOPROPANE, ETC. THESE VENTILATORS ARE NOT
EXPLOSION-PROOF.
