Air is released in a radial form from an outlet portion 40 of each one of the two air supplying sections 4a, 4b.

A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion extending above and behind the user's ears and a lower portion extending below and in front of the user's ears. The device includes components mounted to the frame, comprising an air intake filter mounted on the frame and communicating on one side with ambient air outside the device and on the other side with an inlet duct and an air outlet filter mounted on the frame and communicating on one side with air inside the device and on the other side with ambient air outside the device. The device also includes a battery-powered air mover mounted on the frame and operable to pull air through the air intake filter and through the inlet duct and push air out into the inside of the device and a rechargeable battery mounted on the frame to power the air mover. The device further includes a transparent face shield mounted on one side of the frame in such a way as to create an airtight seal between the face shield and the one side of the frame, a fabric component made from an air impermeable fabric and mounted on the other side of the frame in such a way as to create an airtight seal between the fabric component and the other side of the frame, and to encircle the user's neck, a head harness configured to rest on the user's head and support the frame with its components mounted thereon, and wherein the components are mounted on the upper portion the frame and on the lower portion of the frame so as to achieve a weight distribution ratio between the upper portion of the frame with components mounted thereon and the lower portion of the frame with components mounted thereon, the ratio being between 1 to 1.5 and 1.5 to 1.

A support frame for dust collection system including a drum filter and a filter cleaning system is disclosed where the frame includes a plurality of octagonal supports spaced apart from each other in an axial direction defining an octagon-shaped peripheral profile. A plurality of axial members extend between adjacent octagonal supports, and end covers are secured to the frame members with each cover including a first inlet opening and a second inlet opening. The support frame may be used in a modular dust collection with a plurality of modular segments of filter media segments secured to the frame and a filter cleaner segments corresponding to the filter media segments.

A painting facility 1 includes a painting chamber 3 in which a spray painting operation is effected on a painting object W, an air supplying chamber 2 configured to supply air into the painting chamber 3 via an air supplying section 4a, 4b provided in a ceiling portion 30 of the painting chamber 3, and an air discharging chamber 5 configured to suction air and uncoated paint mist present in the painting chamber 3 via a floor discharging section of the painting chamber 3, two air supplying sections 4a, 4b are disposed in left-right symmetry relative to a position of the painting object W in a width direction of the painting chamber 3 as the center therebetween. Air is released in a radial form from an outlet portion 40 of each one of the two air supplying sections 4a, 4b.

A clothes drying device, where a lint cleaning component and a lint collecting component are both arranged on a mounting component, and the mounting component is arranged on a box body assembly, so that the lint cleaning component and the lint collecting component are arranged at a centralized position in the clothes dryer. The clothes drying device solves the problem in existing clothes dryers that a fiber removing component and a collecting container are arranged at dispersed positions on a clothes dryer and occupy a large amount of space, which affects the overall layout of the clothes dryer such that the overall structure of the clothes dryer is not compact, and downgrades the user experience.

An ember-blocking vent screen for covering a roof vent comprises a screen section and at least two strips of pressure sensitive adhesive (PSA) heavy duty tape attached at opposite edges of the screen section such that deployment portions of the tape strips overlap and extend transversely beyond their respective screen edges. The screen section is made of stainless steel or aluminum wire, has interstices sufficiently small to block passage of small minimum diameter embers therethrough, is lightweight, and is sufficiently malleable to be capable of conforming to the contour of the vent being covered. The deployment portion of the tape strips is such that deployment portions of the tape extend transversely (i.e., widthwise) beyond respective screen edges covered with a release liner that is removable for installation of the screen

A filter arrangement may include a filter element and a gasket element. The gasket element may include a substantially circular flow-through opening and a locking collar. The locking collar may be arranged along a circumference of the flow-through opening with respect to a circumferential direction. The locking collar may form a hollow cylindrical installation space. The filter element may include a filter element body and a substantially hollow-cylindrical counter locking collar. The counter locking collar may include an open axial side and a covered axial side which may be spaced apart from each other with respect to an axial axis. The covered axial side of the counter locking collar may be covered by said filter element body. The counter locking collar may be at least partially inserted into the hollow cylindrical installation space of the locking collar.

The invention relates to a filter for a brake device, comprising a case, a cylindrical tubular filtering element and a dismantlable axial fastening system. The filtering element is located inside the case and the case includes a cylindrical tubular lateral wall having two opposite end edges, a first and a second. The filtering element sits on an internal surface of the lateral wall of the case. The dismantlable axial fastening system provides axial fastening of the filter when same is assembled in the brake device, axial fastening of the filtering element inside the case, and means for assembling and dismantling the filter. The purpose of the filter is to collect all the particles harmful to health that are released each time the brake device brakes, preventing said particles from being transferred to the air that is breathed.
