These small air pumps work on vibrating armature principal. Due to their simpler design, construction & fewer moving marts, these small diaphragm pumps can perform maintenance-free for very long time. Typical life expectancy is 25,000 hours & higher depending upon the specific application, which is virtually impossible to achieve from DC motor pumps including brushless motors. These small air pumps can be used in pressure as well as vacuum mode. These air pumps are available in AC power (12 V, 24 V, 115 V, 220 V) or DC power (12 V, 24 V) to suit customer’s needs.
Pulse Width Modulation (PWM) option is available on certain DC volt version pumps. This unique feature is highly desirable for applications requiring precise control of the pump output.
