A filter element assembly (10) is disclosed comprising: a filter element (12) for location in a housing (4) of a filter (2), comprising a wall (16) of a filtration medium which defines a hollow space (18), for a gas stream to flow from the space through the wall, the filtration medium including a filtration layer (20), and a drainage layer (22) located outside the filtration layer, first (24) and second (26) end caps at opposite ends of the wall, one including a port (28) for a gas stream which communicates with the space; and a drainage promoter (14) comprising a fin (46) which can be fitted to the filter element so that it extends along the filter element substantially an entire distance between the first and second end caps, the fin compressing the drainage layer along its length to promote drainage of liquid which has collected in the drainage layer.

Disclosed herein is a system that performs the separation of incoming liquid and vapor oil by a single system. The disclosure is a compressed air system for separating liquid- and vapor-form oil from the air, including a filter element that comprises an air-oil separator that separates liquid-form oil from the air, an activated carbon filter positioned after the air-oil separator, separating the vapor oil from the air; and a housing, in which the said filter element is placed, having at least two discharge elements for discharging liquid-form oil, an inlet port for the inlet of air and an outlet port for the outlet of the air.

An assembly having an intake connector with an air entrance for an air-conditioning system and a filter element having a concertina bellows having peripheral troughs and peripheral peaks, wherein the filter element has a water-repellent filter medium and wherein the filter element at least partially covers the air entrance, suitable for discharging snow and water, in particular snowmelt, to avoid flow into the air-conditioning system of a motor vehicle and to minimize damage to a filter element, wherein the concertina bellows is disposed so as to be inclined at an angle of 5° to 90°, preferably at an angle of 15° to 85°, in relation to the horizontal, wherein the filter element has an outflow unit for a water outflow from the peripheral troughs.

The compressor is inferiorly provided with a discharge nozzle and with shoes which are seated and affixed against a support plate, incorporated to the air-oil reservoir and provided with an admission hole aligned with the discharge nozzle, and with a tubular column, incorporated to the air-oil reservoir and open to the interior of the latter. The air-oil reservoir further presents: an inner housing receiving a thermostatic valve, connected to the interior of the air-oil reservoir and also to the compressor and to an oil radiator, as a separate device, through cold oil outlet and hot oil outlet nozzles of the air-oil reservoir; openings for the direct coupling of an oil filter and of an air-oil separating filter; and an end housing lodging a minimum pressure valve.

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.

A separating device for separating a liquid from gas is provided with a separating element that has a housing with housing cover closing off an end face of the housing. A filter element is arranged in the housing. A coupling element is provided to couple the separating element to a connector device. The housing cover has a central first gas passage and a second gas passage arranged radially outwardly of the first gas passage. The housing cover has a housing cover thread correlated with the first gas passage. The housing cover thread is to be screwed to a coupling element thread of the coupling element. A fluid discharge channel is arranged within the coupling element for discharging separated liquid from the separating device. The housing cover thread and the coupling element thread, in a position of use of the separating device, are connected substantially seal-tightly to each other.

An automated system for the separation of vapor and liquid from a gas and liquid combination entering a separation vessel. A programmable logic control unit module controls a valve and is programmed for periodic release of separated liquid collected within the vessel upon achieving various conditions within the vessel or upon expiration of a pre-established time interval, with separated liquid delivered via an outlet port through a valve controlled by the programmable logic control unit to a storage tank.

An oil catch apparatus is provided. The oil catch apparatus is capable of efficiently extracting oil from air flowing through the oil catch apparatus while being of compact size. A filter of the oil catch apparatus includes a cylindrically wound main filter unit and a keep member for keeping both ends of the main filter unit. Air flowing into the main filter unit is cleared of impurities upon passing through the main filter unit, and exits out of the main filter unit.

A switchable two-stage coalescence separation system, including a coalescer housing (1), a plurality of two-stage filter elements (2), and a particle detector (5). A lower portion and an upper portion of each of the two-stage filter elements (2) are located in a lower chamber (101) and an upper chamber (102) of the coalescer housing (1), respectively. Two gas inlet branch pipes are communicated with the lower chamber (101) and the upper chamber (102), respectively and are connected to a gas inlet main pipe (8) through a first multi-way valve (6). The particle detector (5) is disposed on the gas inlet main pipe (8). Two outlet branch pipes are communicated with the lower chamber (101) and the upper chamber (102), respectively and are connected to a gas outlet main pipe 13 through a second multi-way valve (7).

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow-establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicle, with or without using flow-establishing devices.
