Abstract: A modular skid mounted oil production system, comprising multiple skid sections that are connectable via alignment pins coupled to the skid beam structure. The alignment pins having a fork connector that is connected to a knife connector. When the skid sections are connected, the piping, electrical, and pneumatic tubing connectors are connectable to the other corresponding skid piping, electrical, and pneumatic tubing connectors without the need for welding or field construction of connecting components. The modular skid oil production system is capable of expansion or contraction as required by the operation of the system. For example the system includes removing a skid section having a larger separator and replacing it with a skid section having a smaller separator, without the need of welding or field construction of connecting components.

Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which primary and secondary filter cartridges, having a media pack and a seal arrangement surrounding the media pack, can be installed. The filter cartridges can include an open end cap with an axially deviating seal arrangement and a plurality of axially extending channels for engaging with ribs on the housing. The filter cartridges can also include extension members extending from the open end cap that include the axially extending channels, entirely or partially. The filter cartridges can also include a guide member extending from the extension members for providing a low friction surface against the housing during installation that allows axial force exerted by the installer to be translated into a rotational force that rotates the filter cartridge during installation.

Abstract: The present invention relates to a separator for vacuum cleaners operating on the basis of a liquid bath, the liquid bath serving as pre-separation and as a dumping area for the aspirated particles. It consists of segments (7), each of the segments (7) being formed as a radially flat ring (13) that is centrally secured to a hub (11) via radial supports (12) and having blades (8) extending equidistantly and substantially perpendicularly to the surface of the ring (13).

Abstract: Systems and methods are provided for predicting failure of an air filter within an HVAC installation. Also provided are methods for calibrating the systems described. The system provided typically includes air filters and vents, and a processor at an application server configured to implement methods described. Each vent may include various sensors, such as a temperature sensor or a sensor for evaluating indoor air quality. The method may receive information about a total volume of air pumped by an HVAC system over time, determine the volumetric quantity of air passing through a particular filter, and compare that quantity of air to a threshold amount representing the lifetime, or some percentage of the lifetime of the filter. Where the system includes multiple vents and multiple filters, the system may implement a model for calculating the volumetric quantity of air associated with each individual filter.
