Supplies clean air into the mask through a hose

Supplied-Air Respiratory Protective Equipment

A supplied-air respirator (airline mask) is a system of respiratory protective equipment that supplies clean air to the wearer through a hose. There are types that use an air compressor or blower as an air source, and there are also types that rely on the wearer’s own lung suction power. By correctly selecting the appropriate type from various supplied-air respirators, the equipment can be used in:

• “Oxygen-deficient environments”
• “Environments generating high concentrations of toxic substances”
• “Environments generating highly toxic substances”

Please accurately assess the working environment and use a supplied-air respirator with the appropriate performance specifications.

Pressure Demand Type Airline Mask

Possesses high protection performance

The pressure demand type maintains positive pressure inside the mask. Even if there is a gap at the face-to-mask seal, air will blow out from inside the mask to the outside, making it difficult for outside air to enter.

The pressure demand type airline mask is structured to supply the necessary amount of air according to the breathing rhythm, while maintaining positive pressure (pressure higher than ambient air) inside the mask regardless of whether inhaling or exhaling. Therefore, in the worst-case scenario where a gap occurs between the mask and the face, air will blow out from inside the mask, helping to prevent the ingress of outside air and allowing for safer work.

Focus on safety Pressure Demand Type

Even if a gap appears in the face contact area, air will blow out forcefully from there, helping to prevent the ingress of oxygen-deficient air, toxic gases, and harmful dust.

● Air supplied by the pressure demand valve maintains a positive pressure state inside the mask thanks to a balance spring at the exhalation valve unit.

Examples of supplied-air respirator applications

A mask that easily and snugly fits the face

High Scope V mask with HAWC lip structure

The product applies the “HAWC lip※” technology with a wide, flexible, and specially curved face contact shape that creates a “suction cup effect” to enhance the seal. This provides high airtightness, a wide field of vision, and lightweight design.

※Abbreviation for High Adaptable Wide Concave (the company’s proprietary face contact structure).

The HAWC lip face contact area can fit snugly to the face like a suction cup.

List of Types

For Sakai-type supplied-air respirators, please confirm the working environment, equipment, and number of users in advance to select the most suitable product for the workplace.

Compressed Air Supply (Using equipment such as an air compressor)

Airline Mask

The system is divided into 3 main groups:

1. Pressure Demand Type

• Features: Used for work in environments requiring high airtightness.
• Style: Facepiece Type.
• Example: Model 17HVG-ZW, etc.

2. Demand Type

Features: A type that supplies only the necessary amount of air to the wearer.

3. Constant Flow Type

Features: Used for continuous work over a long period within a fixed range.
Classification by style:

A. Facepiece Type

• Portable filter type: e.g., Model 12HV-Y, etc.
• Fixed filter type: e.g., Model 12D-Z, etc.

B. Hood Type

• Portable filter type: e.g., Model M5-Y, etc.
• Fixed filter type: e.g., Model S1-Z, etc.

C. Face Shield Type

• Fixed filter type: e.g., Model AFP-1.

Blowing or Suctioning of Ambient Air

No air compressor required
Hose Mask

The system is divided into 2 main groups:

1. Electric Blower Type

• Features/Applications: Used for repairing plant equipment, working in manholes, pits, etc.
• Style: Facepiece Type.
• Example: Model SHV-105, etc.

2. Lung Power Suction Type

• Features/Applications: Used for tasks where a suitable breathing air source can be reached within a 10m range.
• Style: Facepiece Type.
• Example: Model 1 H-C, etc.

DANGER

• Half-face masks, hood types, face shield types, and lung power suction types (both full-face and half-face) MUST NOT be used in cases of short-term exposure to hazardous substances that pose an immediate danger to life or health.
• Individuals with beards, sideburns, or bangs that interfere with the face seal, or with mustaches or chin hair that hinder the operation of the exhalation valve, MUST NOT use facepiece-type supplied-air respirators.

Pressure Demand Type Airline Mask

The pressure demand type maintains positive pressure inside the mask even during inhalation, which makes it difficult for outside air to enter even if a gap occurs at the face seal.

[Specifications]

• Minimum required air volume: 115 L/min
• Maximum hose length: 100 M

[Safety Warnings] ⚠ DANGER: Always check the supplied air volume.

[Additional Features] Whistle (Warning Device): In the event that the supply pressure drops to the level of 0.30 ~ 0.35 MPa, a warning sound will be emitted from the air whistle.

Non-electric Emergency Air Supply Switching Warning Device

Sakai Type Automatic Backup Unit – Model ABU-10

• In the unlikely event that the regular air supply stops, the device immediately switches to the backup cylinder air supply. Simultaneously, a warning sound will be emitted to notify the worker of the incident and urge evacuation.
• No power source required.
• Integrated air filter and mist separator.
• Can connect up to 2 airline masks.

※The product does not include: Airline masks, medium-pressure hoses, hose reels, cylinders, and carts.

Personal protective equipment such as safety clothing, helmets, workwear, gloves, etc., shown in the wearing illustration are not included with the product.
