General Information
Description
The Large Animal Volume Controlled Ventilator, Model 613, is designed for use with
dogs and other large animals over 1 kilogram body weight. It has variable controls for
inspiration rate (speed control) and inspiratory ratios ranging from 25-50%.The verti-
cal slide valve provides separate pathways for inspired and expired air.
Volume adjustment is made on the piston shaft, and therefore accurate volume adjust-
ment cannot be made while the ventilator is running. However, the rate and the I:E %
can be varied while the ventilator is running.
Air/gas valving is by the four port system with separate ports for gas inlet, gas outlet
(to animal), gas return (from animal), and ventilator exhaust.
The gas inlet can be used to supply air or any non-flammable gas supply. Like the other
Harvard mechanical ventilators, attachment of the ventilator exhaust to a column of
water can be used to produce a positive and expiratory pressure (PEEP).
Specifications
Volume Adjustable from 30 to 750 cc/stroke. Note: Volume adjust-
ment is made on crank, and therefore accurate volume
adjustments cannot be made while ventilator is running
Rate Adjustable from 7 to 50 strokes/min while ventilator is run-
ning
Phase Adjustable from 25 to 50% of single stroke cycle continuous-
ly variable while pump is in operation

max
Inspire/Expire Ratio 25/75 to 50/50
Motor Dual phase, 1/15 h.p. gear head motor
Variable Speed Control Motor speed is electronically controlled by solid state SCR
system. AC line voltage is rectified to provide fixed DC volt-
age to motor field and variable DC voltage to armature
Variable Phase Control Solid-state, dual phase electronic motor control is coupled to
DC shunt wound motor. Cam-actuated micro-switch operates
electronic phase control.
Fuse Motor control is protected by 2 Amp Slo-Blo fuse. DO NOT
REPLACE with higher-rated fuse.
Plug 3-prong molded connector
