The air-particle separation system is a dust handler that includes a main body with a misting module mounted thereon. The misting module includes air input pipes for receiving air with particles and a misting nozzle for soaking the particles within the air stream. The water particles and air are directed downwardly into a screen basket that is supported in a first chamber. A screen purging nozzle removes any particles stuck to the screen. Air is pulled through the system by a suction fan. An optional high-pressure fan may also be provided. The water, the water-soaked particles, and the air exit the screen basket and enter the first chamber and a second chamber. Air is removed from the chambers through the fan(s), while a drain in the bottom of the chambers drains the water and particles.

An oil mist collector contains a casing unit, a first filtering unit, a second filtering unit, and a ventilation unit. The casing unit includes an inlet, a first air chamber, a second air chamber, an air guiding orifice corresponding to the second air chamber and communicating with an exterior, and a first recycling orifice arranged on a bottom end thereof and communicating with the first air chamber. The first filtering unit is disposed in the first air chamber and corresponds to the inlet. The second filtering unit is fixed above the air guiding orifice and includes an open rear end, a first lip with a noncircular cross section, a second lip, and a first filtration assembly defined between the first lip and the second lip. The ventilation unit includes a motor and a rotary fan rotatably connected with the motor and secured in the second air chamber.

A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

A fluid filter with a housing, a releasable cover, and a replaceable filter having a filter body and two end discs. The filter is plugged onto a housing pipe and a locking ring is guided on the pipe, preloaded in a push-out direction. The locking ring is locked in a pushed-out position by a locking device. An unlocking device guided by the filter unlocks the locking device when the filter is pushed onto the pipe and enables the locking ring and the filter to be pushed in. When the filter is fitted into the housing, a seal on the end disc or locking ring interacts with a housing sealing surface to separate an untreated filter side from a clean side. When the locking ring is in the pushed-out position and the filter bears against the locking ring, the seal is held away from the sealing surface of the housing.

The present invention relates to a filter unit (10) for a compressor, comprising a housing (12) with an inlet (14) and an outlet (28) for gas to be compressed, a particle pre-filter (16) arranged downstream of the inlet (14) in the flow direction of the gas to be compressed, an ultraviolet irradiation unit (22) which is configured to emit ultraviolet light and is arranged downstream of the particle pre-filter (16) in the flow direction of the gas to be compressed, and a ballast (40) which is configured and arranged to control the ultraviolet irradiation unit (22). The filter unit (10) is designed in such a way that the gas to be compressed which is fed in at the inlet (14) first passes through the particle pre-filter (16), is then irradiated by the ultraviolet irradiation unit (22) and can finally be fed to the compressor through the outlet (28). The invention also relates to a compressor comprising such a filter unit (10) and to a method for compressing breathing air using such a compressor.

A dust suction system for a dry degreasing and deburring machine includes an air suction circuit, a suction fan, a settling chamber provided with a filter cartridge, and an unclogging unit provided for injecting a flow of unclogging air into the filter cartridge during an unclogging operation. The dust suction system includes a control unit that controls the fan and the unclogging unit depending on measurements of pressure and load in the air suction circuit.
