Air Injectors

Electronic Air Injector

A Waikato electronic air injector is the power behind the best slug wash systems.

Digitally controlled using only the best electronics and adjusted easily, this 24 volt air Injector fits any milking machine where a slug wash system is used. Cycle timing (on time) can be selected between 1 and 29 seconds. Air blast time can be adjusted between 1 and 10 by simply turning a bezel. This increases or decreases the volume of air entering the milking machine allowing infinite tuning of the wash system. The adjustment permits air entry from 1000 to 4500Lpm.

A "push fit" over a 32mm pipe connection reduces installation time. A Hush Kit available as an option and fits snugly over the injector to minimize any noise.

An adjustable electronic air injector ensures precise wash system set-up and a repeatable wash process every time.
