Half Mask Respirator

Half Mask Respirator with Dual Bayonet Connection | Silicone Facepiece for Multi-Hazard Protection

The silicone Half Mask Respirator comes from Xi'An PPE MAX Co., Ltd. Breathing protection gear has been built at that factory since 1956. CE EN 140:1998 covers this model. Liquid silicone rubber (LSR) is why the fit stays kind to skin. The shape also holds up over time. Sizes are S, M, and L. A dual bayonet connection lets modular filter cartridges clip straight on. Those cartridges handle gases, vapors or particulates. B2B buyers after tough respiratory protection for many kinds of industrial settings will find it a practical pick.

What Is This Product?

A tight seal forms over the nose and mouth with This product. Fit the right cartridges or filters, and the unit works as an air-purifying respirator.

Disposable N95-style masks take another route. Here the facepiece is a reusable elastomeric one. Contours of the face get followed by the silicone skirt. That lowers Total Inward Leakage (TIL) and gives a stronger seal.

The facepiece gets worn again and again. That mask body stays in service. Only the filter media is swapped out. Sites that equip a number of workers see procurement costs drop over time. Particulates and dust still get covered, along with organic vapors, acid gases and similar hazards.

Features

Liquid Silicone Rubber Facepiece

LSR brings hypoallergenic properties. Heat won't break it down easily, and the shape stays put. Many disinfection cycles later, the material is still neither sticky nor brittle.

Dual Bayonet Connection

Filters click on fast and hold firm with a dual bayonet interface. Connector tolerances stay within ±0.1 mm. Every filter locks flush. Air gets no gap to bypass.

Low-Profile Design

It sits low on the face. Straight over the top go welding shields and safety visors, no fight needed. On car assembly lines or building sites, where workers mix PPE, that counts for a lot.

Wide-Opening Exhalation Valve

The big exhalation valve lets air out quickly. Less CO₂ gets trapped in the mask, so dead space drops. Heat builds up more slowly too. For people who wear it through long shifts, that makes the day feel easier.

4-Point Head Suspension System

Four adjustable straps spread the pressure evenly. The harness goes through cyclic tensile testing. That check shows the elasticity and the durability of the Half Mask Respirator still hold when the mask is used again and again.

Three Size Options

You can get it in S, M, and L. One of those sizes should suit most face shapes. That makes fit test compliance easier to handle for a full crew.

Applications

Industrial Painting & Surface Coating

High VOC and isocyanate levels turn up often in shops that work on cars and aircraft. The respirator handles those places with Organic Vapor (OV) cartridges and P95 pre-filters. It sits low on the face. So a protective hood goes over it. The seal still holds.

Construction & Mining: Silica Dust Under Control

Cutting concrete or masonry puts a worker in contact with crystalline silica. Below 0.3 microns, particles get trapped by a P100 (HEPA) pancake filter at 99.97%. Disposables are the weak spot once dust loads get heavy. The elastomeric seal keeps holding under those conditions.

Agricultural Chemical Handling

Mixing and spraying pesticides releases corrosive fumes. That is the job multi-gas cartridges (Ammonia, Methylamine, Acid Gas) are made for. Chemical vapors pass right through disposable masks. Cartridges fit this respirator, so vapor protection comes built in.

Why Choose Us?

Protective equipment has been PPE MAX's line of work since 1956. Five checkpoints make up our quality control process. TIL testing covers several face shapes. Exhalation valve seating gets checked too. Harness tensile strength is cycled, and bayonet connectors must land within ±0.1 mm. The silicone reversion test comes after repeated disinfection.

Documented product specs ship out with every B2B order. Sizing stays consistent. Ask us, and the full CE certification records are yours. Filter compatibility is something our team can talk through with you. Replacement schedules and sizing needs can be discussed too, before the order and after it.

Packing & Orders

Packing is built to keep facepiece shape and valve integrity intact on international shipments. Need a particular packing setup or label option? Get in touch with us for that, or to ask about order quantities.

After-Sales Support

Which filters fit? When should you swap them, how do you clean them, and how many people do you need? Our team can help with all of it. Valves and harnesses come sold on their own. Buy them, and each unit stays in service longer.

Trade Shows & Factory Visits

PPE MAX participates in international occupational safety trade exhibitions. We welcome factory visits from B2B buyers who want to review our Half Mask Respirator production process and quality control procedures in person.

FAQ

Q: How does this differ from an N95 for industrial use?

A: N95s are disposable and filter particulates only. This this product uses a reusable silicone facepiece with a more robust seal and supports interchangeable cartridges for gas, vapor, and particulate protection — at a lower cost-per-use over time.

Q: When should cartridges be replaced?

A: Once your breathing gets clearly harder, swap out the P100 particulate filters. Cartridges for gas and vapor do not follow the same rule. You need a written schedule for changes. The contaminant concentration should set that schedule. Talk to your workplace safety officer, or check the OSHA or HSE guidelines that cover your application. If the contaminant ever reaches your nose or taste buds, change the cartridge right away.

Q: Can it be worn with facial hair?

A: No. A beard, or even stubble, can stop the facepiece from sealing. Once that seal breaks, the protection factor falls a lot. Anyone with facial hair should wear a PAPR with a loose-fitting hood instead.

Q: What is the correct cleaning method?

A: Pull the filters off first, then wash the facepiece. Filters never go in the wash. For soaking, use warm water under 50°C and a neutral detergent. Cleaners with lanolin and solvents like acetone eat into silicone. Keep them away from it. Check every valve before you put the unit back together.

Q: Is a fit test required?

A: Yes. Some workplaces come under OSHA (USA) or HSE (UK) rules. Where those rules apply, a fit test is required every year. You can run it as Quantitative (PortaCount) or Qualitative (Bitrex/Saccharin). What the test proves is that the exact size and model seals to each user's face.

Q: What sizes can I get, and how do I know which one fits me?

A: The respirator comes in S, M, or L. A fit test result tells you which size to take. So does a hands-on fit check. Buying for a whole team? Ask us for a size kit. It lets you test the fit across your staff first, before you place a bulk order.
