Air Purifying Respirators

Air Purifying Respirators Half-Face Mask | Liquid Silicone, CE EN 140:1998

Since 1956, Xi'An PPE MAX Co., Ltd has built personal protective equipment. The half-face model in our Air Purifying Respirators line is made of liquid silicone. Size Medium is the one we offer. CE EN 140:1998 is the European standard for half-mask performance, and this unit is certified to it. Inhale and exhale resistance, CO₂ clearance, and facepiece leakage all fall under that standard. Dust filter cartridges screw onto a bayonet connector. Gas filter cartridges fit the same mount. The head and neck belts adjust. That keeps the seal tight on many face shapes, even after long wear.

What Are This Product?

One kind of personal protective equipment is the air purifying respirator. It keeps harmful contaminants in the air away from the wearer. Surrounding air gets pulled in through a filter or an adsorbing element. Particles are trapped there. Chemical vapors stop there too. So do biological aerosols. None of it reaches the lungs.

This product work differently from atmosphere-supplying units like SCBAs. The wearer's own breathing pulls air through the purifying cartridge. No oxygen comes from the unit. Keep them out of oxygen-deficient environments (below 19.5% O₂).

Three groups of workplace hazard are where APRs usually come in:

• Occupational particulate disease. Years of breathing silica dust or asbestos fibers can bring it on. Fine particulates do damage too. Silicosis, COPD, and similar conditions are the outcome
• Acute chemical exposure in industrial settings. VOCs are behind most cases, and so are acid gases and metal fumes
• Biohazards and fine particles are a real risk in healthcare jobs, pharmaceutical work, or abatement work

Product Features

Liquid Silicone Facepiece

Regular rubber has a harder feel to it. Liquid silicone gives more when you bend it and stretches farther. Around the face it sits tight. Long shifts get kinder to pressure points because of that. Thermoplastic choices break down faster under UV and chemical vapors.

Bayonet Dual-Filter Connector

The bayonet-style port accepts dust filter cartridges and gas filter cartridges. Switch the filter type to match the specific hazard. You do not need to replace the facepiece.

Adjustable Head and Neck Belt

Two independent adjustment points — head and neck — allow wearers to achieve a consistent seal across different face shapes. A stable seal is the primary determinant of actual field protection.

CE EN 140:1998 Certification

In Europe, half-mask respirators are covered by this Air Purifying Respirators standard. Breathing resistance counts, both going in and coming out. Dead space, meaning CO₂ clearance, matters as well. So does leakage around the facepiece. A certificate is proof the mask meets the minimum thresholds the standard sets.

Key Advantages

• Reusable facepiece: the silicone body is durable; only the filter cartridges require periodic replacement
• Modular filter compatibility: swap the cartridges and one facepiece platform handles several hazard categories
• Adjustable fit: the head and neck belt system fits a range of face shapes and sizes
• Lighter than full-face systems: moving around tight or hard-to-reach work areas gets much easier
• Easy to maintain: the liquid silicone wipes clean, so storing it between jobs takes very little effort

Typical Applications

Engineering controls on their own sometimes cannot bring contaminant exposure down to safe limits. When that happens, this type of air purifying respirator is used.

Heavy Manufacturing and Welding

Appropriate gas and dust filter cartridges connected via the bayonet port address metal fumes — including those from grinding and smelting operations — and oil mists where P-series cartridges are indicated.

Chemical Processing and Spray Painting

Organic vapor cartridges fit bayonet connectors. Spray booths count on that setup. Chemical processing lines do the same. Where VOC, solvent, or lacquer vapor is a worry, this setup handles the job.

Asbestos Abatement and Pharmaceutical Handling

Fine fibers call for high-efficiency particulate filter cartridges. Dust from active pharmaceutical ingredients (API) does too. Both click into the bayonet port. On jobs like these, a face seal you can check counts. The facepiece uses silicone, which helps form that seal. Leave out that material, and quantitative fit testing (QNFT) cannot go ahead.

Construction and Demolition

Dust filter cartridges attach through the bayonet port. They limit exposure to concrete dust, drywall particles, and renovation debris.

About PPE MAX and Air Purifying Respirators

Xi'An PPE MAX Co., Ltd has made personal protective equipment since 1956. B2B buyers come to the company for steady quality across repeat orders. They also need documented certifications for compliance audits. Having a supplier with production infrastructure already in place matters to them too.

The liquid silicone half-face respirator also covers filter sourcing help. That means Air Purifying Respirators and bayonet-compatible units too. Buying teams can settle on a single facepiece platform this way. One platform then handles several hazard categories on site.

FAQ

Q: Can you wear these respirators in places where the oxygen level is low?

A: No. All an air purifying respirator does is trap contaminants. Oxygen? It gives you none. Only wear one where the air around you holds at least 19.5% oxygen. Below that level, you need an SCBA or a supplied-air respirator.

Q: What kind of lifespan do chemical cartridges have?

A: Several things decide how long a cartridge lasts. The amount of contaminant in the air is the biggest factor. Humidity plays a part as well. So does temperature. Your breathing rate matters too. Put a written replacement schedule in place for your site. Does the air start to taste or smell off? Do you feel any irritation? Get out of the area. Change the cartridge at once.

Q: Does facial hair affect the seal?

A: Yes. Hair trapped at the seal gives unfiltered air a path past the facepiece. For tight fitting half face respirators, the rules often call for a clean shaven seal area. Find the occupational health regulation that covers your workplace.

Q: What filter classification system applies to this mask?

A: This mask holds CE certification under EN 140:1998. CE marking should also appear on any filter cartridges used with it. Those cartridges also have to meet the EN filter standards for their type. Particle filters fall under EN 143. Gas and combination filters fall under EN 14387. In North America, NIOSH relies on the N/P rating system. That is a separate classification. Products with CE marking are not covered by it.

Q: What is the right way to store the silicone facepiece?

A: Clean it after every use, then let it dry. A sealed bag works well for storage. Sunlight will damage it, so will heat sources and chemical vapors. Silicone breaks down when UV or chemicals reach it for long stretches. The face seal can then stop holding.

Q: What filter types fit the bayonet connector?

A: This bayonet connector takes dust filter cartridges. Gas filter cartridges fit it as well. Need to check a certain filter brand, or a hazard category for your site? Get in touch and we will confirm it.
