摘要： Embodiments relate generally to noise reduction techniques and systems for use with supplied air respirators. Typical embodiments may comprise porous elements located within a respirator system operable to alter the air flow pattern through the system and therefore reduce noise created in the system. These porous elements might be located within an inhalation valve, a breathing hose and/or a muffler block housing of a respirator system.

摘要： Embodiments of methods of assembling an abrasive blast respirator are disclosed. The method may comprise removably attaching an exhalation valve into an exhalation valve port of a facepiece, removably installing the facepiece into a hood, removably attaching a filter to a first inhalation valve, where the first inhalation valve is coupled to the facepiece, and removably attaching a breathing hose to a second inhalation valve, where the second inhalation valve is coupled to the facepiece.

摘要： An accessory cap for a respiratory cartridge includes a housing having a front wall and a side wall which cooperate to define an interior cavity. The side wall includes a retaining formation configured and arranged to releasably engage and hold the housing on the respiratory cartridge. The housing includes a downwardly facing air passage configured to allow air to pass from an exterior environment to the interior cavity. The accessory cap further includes a pre-filter support web removably received within the interior cavity and spaced inwardly from the front wall. The housing and the pre-filter support web form a pre-filter cavity within the interior cavity adjacent to the front wall. The accessory cap can function as a standalone shower cap, or a pre-filter media can be optionally inserted into the pre-filter cavity so that the accessory cap functions as a combination pre-filter and a shower cap.
摘要翻译： 用于呼吸筒的附件盖包括具有前壁和侧壁的壳体，其配合以限定内腔。 侧壁包括构造和布置成可释放地接合和保持壳体在呼吸盒上的保持结构。 壳体包括面向下的空气通道，其构造成允许空气从外部环境传递到内部空腔。 附件盖还包括可移除地容纳在内部空腔内并与前壁向内间隔开的预过滤器支撑腹板。 壳体和预过滤器支撑腹板在邻近前壁的内腔内形成预过滤腔。 附件盖可以用作独立的淋浴帽，或者可以将预过滤介质可选地插入预过滤器空腔中，使得附件盖用作组合预过滤器和淋浴帽。

摘要： A sealing device for positive pressure testing is attached to a respirator face mask and includes an outer frame integrally joined to a movable cap by a flexible link that biases the cap in an open position for the operational use of the face mask against a manually applied force to move the cap to a sealed position for the positive pressure testing to assure the proper fit of the face mask on the wearer. The method for positive pressure testing includes flexibly moving the sealing device from the open position to the sealing position such that the sealing surface of the cap seals the exhalation valve assembly closed. The wearer then exhales into the mask to test the seal of the mask. When the test is completed, the sealing device is released and the inherent biasing force moves the cap from the sealing position to the open position.
摘要翻译： 用于正压力测试的密封装置附接到呼吸器面罩，并且包括通过柔性连杆整体连接到可动盖的外框架，该柔性连杆将盖子偏压在打开位置，以防止手工施加的力 以将盖移动到用于正压力测试的密封位置，以确保面罩适合佩戴者。 用于正压力测试的方法包括将密封装置从打开位置灵活地移动到密封位置，使得盖的密封表面密封呼气阀组件。 然后佩戴者然后呼出面罩以测试面罩的密封。 当测试完成时，密封装置被释放并且固有的偏压力将盖从密封位置移动到打开位置。
