自吸式长管呼吸器
自吸式长管呼吸器又称贮气式防毒长管面具，有时也称为防尘长管面具。是借助人的肺力吸入经过滤的新鲜空气，达到保护人体呼吸系统的安全防护装备（管长10米，1人使用）进气端必须放置于无污染环境。自吸负压式长管空气呼吸器是一种为个人配备的用于呼吸保护的装备。用于在有毒有害缺氧的环境中进行救护、维修等工作。广泛应用于化工业、石油业、船舶维修喷漆、自来水、煤气及实验室等行业。 结构呼吸器采用自吸式供气，气源为常压的大气空气。自吸式长管面具主要由全面罩（半面罩）、0.5米导气管、可靠地腰带、10米进口波纹长管、快速接头、0.3微米防尘过滤罐、过滤罐支架。使用时把导气管一端放到有新鲜空气的地方即可，呼吸阻力微小，使用简单，经济实惠。
Self-priming long tube apparatus is also called the reservoir type gas mask long tube, sometimes referred to as the dustproof mask long tube.Is with the help of a person\'s lungs inhale filtered fresh air, to protect the safety of human respiratory protective equipment (10 meters long, 1 person use) inlet end must be placed in a pollution-free environment.Since the long tube type suction a negative pressure air breathing apparatus is a kind of for inpiduals with used in respiratory protection equipment.For the poisonous and harmful anoxic environment care, maintenance, etc.Widely used in chemical industry, oil industry, ship repair paint, water, gas and laboratory, etc.Respirator use self-priming gas supply structure, gas source for atmospheric air atmosphere.Self-priming mask long tube is mainly composed of comprehensive cover (half mask), 0.5 meters of airway, reliably belt, 10 meters long imported corrugated pipe, quick joint, 0.3 micron dust filtering tank, filtering tank support.When using the airway end where there is fresh air, breathing resistance small, using a simple, economical and practical.
该款长管呼吸器主要适用于以下几种情况中使用：
The long tube used in respirator is mainly suitable for the following situations:
1、在不明原因的有毒有害环境，用户在不了解所在环境中毒气的种类、浓度等条件下，不容易确定使用何种过滤式防毒面具。
The poisonous and harmful environment in unknown reason, the user do not know where and the concentration of the gas species in the environment condition, it is not easy to determine which filter type gas mask to use.
2、高毒有害环境如一氧化碳、氰化物等。
High toxic and harmful environment such as carbon monoxide, cyanide, etc.
3、高浓度毒烟、毒雾、放射性灰尘。
High concentrations of toxic smoke and fumes, and radioactive dust.
4、有害环境中同时存在多种有害毒气。此种面具采用无毒无害无刺激性的材料制成、金属材料部分进行了防腐处理，不但美观而且便于保存。
Harmful environment at the same time there are many harmful gas.This kind of mask adopts non-toxic harmless without excitant material, metal material part anticorrosive processing, is not only beautiful but also easy to save.when the airway end where there is fresh air, breathing resistance small, using a simple, economical and practical.
