Provided is a pneumatic system for a vehicle, in particular a commercial vehicle. The system comprises a compressor, an air dryer cartridge, and a purge valve. The purge valve is protected by a filter. The filter is arranged in a housing and covers an inlet of an air channel formed in the housing which connects the inlet and the purge valve.

A filter housing assembly includes a base plate, an adapter block, and a shroud. The base plate may be permanently installed in a fluid-conveying system of conduits. A filter member is secured to a filter-receiving formation such as a pipe nipple extending from the adapter block and the shroud is secured to the adapter block to cover and seal the filter member. The adapter block is releasably secured to the base plate. The arrangement facilitates insertion and removal of the filter housing assembly into and out of the fluid-conveying system of conduits by converting multiple junction points into a single junction point, at which a subassembly consisting of just the shroud and the adapter block are connected into the system.

A liquid separator comprises a vessel with an inlet for a liquid/gas mixture. The vessel defines a space sealed at the top by means of a lid in which is situated an outlet to discharge treated gas. A shield is provided in the space extending around the outlet as of the lid, and a filter element provided within the shield. An outlet zone is defined between the shield and the filter element, wherein the outlet zone is in connection with the outlet. The shield comprises a bottom wall with at least one inlet opening and connection means for attaching the filter element onto the bottom wall. The connection means is configured such that the filter element, in a mounted condition, extends around the inlet opening as from the bottom wall, within a chamber defined by the shield, the lid and the bottom wall.

A dual-stage sand and gas separator for use within a wellbore of a fluid producing well is disclosed. During sand separation, fluid is ported into a vortex housing and across a vortex cup which imparts a vortex motion on the fluid to separate solids from the fluid. Some of the solids are filtered by a sand filter screen, while heavier solids are diverted down hole by a diverter plate. The fluid pass internally through the vortex cup into the gas separation housing. During the gas separation phase, a sump is created by the transfer tubing and gas is separated from the fluid and ported away from the tubing.

An assembly is disclosed. The assembly includes a filter frame including one or more cutouts for permitting airflow therethrough. The assembly further includes one or more vertical support members and one or more horizontal support members, wherein the one or more vertical support members and the one or more horizontal support members are fixed to a first side of the filter frame.

A solid pet waste vacuum and bagging device is described. The device is equipped with a canister, collection chute, vacuum motor, and a bag cartridge. The device eliminates the need for an individual to come into any contact with pet waste, including the temperature and the smell conventionally known to emanate from pet waste. The device employs the vacuum motor to collect pet waste within the bag via the collection chute. The collection chute is lined with a plastic bag, which is sealed and released from the collection chute within the canister upon activation of a dispose button by the user. The device is powered by rechargeable batteries, and may be equipped with a charging cradle to maintain a fully charged battery.
