Abstract
A replaceable air filter system for milking machine pulsators has a base with an internal channel that communicates with the air inlet of a milking machine pulsator when the base is mounted on the pulsator. An air filter section is releasably mounted to the base and includes a case, air filter medium attached to the case, and a connector extending from the case which connects to an open bore of the base. The air filter section can be releasably secured to the base. The air filter medium may be formed of multi-fold filter material to provide a large area filter for the input air. When the filter medium is saturated or clogged, an operator can detach the air filter section from the base and replace it with a new air filter section quickly and conveniently.
