It effectively prevents workers from being exposed to dust, and by blowing air with an intake aid, it assists breathing and reduces breathlessness.

It effectively prevents workers from being exposed to dust, and by blowing air with an intake aid, it assists breathing and reduces breathlessness.

DUST RESPIRATORS WITH AN INHALATION ASSISTING DEVICE not only functions as a dust mask, but also uses an inhalation aid to deliver clean air, reducing the wearer's breathlessness while working.
Compared to the P-PAPR, the mask does not always provide positive pressure when breathing because the electric fan blows less air, but high protective performance can be obtained by properly fitting and fitting the mask to the face contact area.
*"THE POWERED AIR-PURIFYING RESPIRATOR(P-PAPR)" was one of the types of "respiratory protectors with electric fans," but it was added to the category of "dust masks" in the revision of the standards for dust masks on April 25, 2018, and DUST RESPIRATORS WITH AN INHALATION ASSISTING DEVICE.


Points for selection
It is necessary to use one that has passed national certification.
Select the product according to its closeness to the face and work environment.
Target works
Work in places where dust, etc. is generated or present.
Work sites with large amounts of dust make it difficult to breathe with disposable dust masks.
Work such as welding, polishing, crushing, cutting, drilling, etc.

Based on our core technology of controlling light, which we have been accumulating for over 100 years since our foundation, we have been developing industrial safety eyewear, including laser safety glasses, and various types of protective equipment.

Also, using our filter technology built up over 30 years, we have been pioneering the industry by developing dust masks and powered air-purifying respirators and continue to present new products to the market.

Moving forward, it is Yamamoto Kogaku's hope to support not only the bodily safety of workers but all aspects of people's lifestyles for safer, more comfortable living environments.

  • Light control technology
    Light control technology
    At worksites with welding, laser processing, and other such jobs, intense, yet invisible light like UV rays and infrared rays are emitted from high-output equipment in high amounts, harming workers' eyes. Yamamoto Kogaku products absorb, reflect, permeate, and polarize particular light and wavelengths for optional and various aspects of control, in turn offering workers safety and heightened performance.
  • Coating technology
    Coating technology
    Lens coating is a deciding factor in glasses functionality including work efficiency and vision safety. From the addition of fundamental anti-fogging and stain resistance abilities in lenses to offering reflection rates, wavelength attributes, and other light-related abilities, a variety of possibilities unfold relating to the environment of use and function requirements.
  • Safety structure design
    Safety structure design
    Yamamoto Kogaku is the only manufacturer in Japan to consolidate in-house lens development grounded in specialized optical function and frame design based on ergonomics showcasing the full extent of the lens' capabilities as well as the consequent production and sale.
    We offer safety products in line with numerous standards, including JIS (Japanese Industrial Standards), ANSI (American National Standards Institute), EN (Europäische Norm, or European Standard), and CE (Conformité Européenne, or European Conformity) marking.
  • Filter technology
    Filter technology
    Our high-performance filter technology, providing high filtration rate and low ventilation resistance, is employed in numerous products, such as powered air-purifying respirator PAPR, dust masks with respiratory assist devices, and disposable dust masks, which passed the Ministry of Health, Labor and Welfare's type certification (National Assay) and allows for a clear field of vision and safe breathing conditions for workers.
