OPTREL Swissair Nasal Foam (Pack of 5)

Nasal foam for Optrel SwissAir mask (x5), Official replacement accessory

The Optrel SwissAir nasal foam is a critical wear part: without it, filtered air leaks around the nose and the protection level drops to zero. This pack of 5 official nasal foams (ref. 4160.530) allows you to anticipate replacements without ever interrupting a job site.

At Dagobert Industrie, we only offer genuine Optrel parts, no generics, no approximate compatibility.

Role and function of the nasal foam in the Optrel SwissAir mask

The Optrel SwissAir mask is a powered air-purifying respirator (PAPR) system. Its design incorporates a nasal foam positioned inside the mask, at the level of the nose and upper lip.

Its role is simple: it creates a flexible barrier between the face and the rigid mask shell. Without it, filtered air can leak out the sides, directly reducing the effectiveness of the system.

How the nasal foam contributes to the seal and comfort of the SwissAir

The foam adapts to facial contours thanks to its compressible cellular structure. It compensates for anatomical irregularities where a rigid shell cannot adjust on its own.

In terms of sealing, it reduces unfiltered air intake around the nose. This is particularly critical during welding, grinding, or chemical spray operations.

In terms of comfort, it absorbs contact pressure and limits skin irritation during long wear sessions. An uncomfortable mask is often worn incorrectly, which negates any protection.

The foam degrades over time: permanent compression, clogging, and loss of elasticity. Regularly replacing this part is essential to maintain the SwissAir's performance at its original level.

This pack of 5 nasal foams is the official Optrel replacement part, compatible exclusively with the SwissAir mask. At Dagobert Industrie, we only offer original accessories to guarantee this compatibility.

Technical specifications of the Optrel SwissAir nasal foam (ref. 4160.530)

The Optrel nasal foam ref. 4160.530 is the official replacement part for the Optrel SwissAir welding mask. It is positioned between the mask and the face to ensure sealing and comfort at the nose.

Its flexible and adaptable material conforms to the morphology of the face. It reduces parasitic air leaks and improves the efficiency of the SwissAir's integrated filtration system.

This consumable must be replaced regularly according to the intensity of use. A clogged or deformed foam degrades comfort and can compromise the mask's seal.

Main features:

• Manufacturer reference: 4160.530
• Compatibility: Optrel SwissAir mask exclusively
• Flexible, lightweight, sweat-resistant material
• Simple, tool-free attachment
• Sold in packs of 5 pieces

This 5-unit pack allows you to anticipate replacements without interrupting your work. It is the solution recommended by Optrel to maintain the original performance of the SwissAir.

At Dagobert Industrie, we only offer genuine Optrel parts, guaranteeing perfect compatibility and the maintenance of the mask's certifications.

Compatibility: which mask and equipment is this foam intended for?

This nasal foam is designed exclusively for the Optrel SwissAir powered respirator mask. It is not suitable for other masks in the Optrel range (e3000, panoramaxx…) nor for masks from other manufacturers.

The SwissAir is a laminar airflow blower mask, used primarily in welding, grinding, and tasks that generate dust or fumes. The nasal foam is positioned inside the mask, between the nose and the visor, to block fine particles that might bypass the airflow.

It is compatible with all versions of the SwissAir, whether used alone or coupled with an Optrel welding helmet (e3000X series, panoramaxx cliff…).

Comparative table of main replacement accessories for the SwissAir mask

Accessory	Optrel Reference	Role	Replacement frequency
Nasal foam (this product)	5000.070	Mechanical filtration at the nose	As soon as visibly dirty
P3 particle filter	5000.160	Main filtration of fine particles	According to exposure, every 1 to 3 months
A2P3 combination filter	5000.162	Particle + organic vapor filtration	According to exposure and saturation
Inner liner	5000.072	Comfort and hygiene in contact with face	Regular washing or monthly replacement
Spare battery	5000.080	Fan power supply	According to charge cycles / aging

The nasal foam is the most frequently replaced consumable on the SwissAir. Its role is complementary to the main filters: it constitutes a first mechanical barrier before air reaches the respiratory tract.

When and why replace the nasal foam of your SwissAir mask?

The nasal foam of the Optrel SwissAir mask is a wear part. It becomes compressed, dirty, and loses its sealing ability over time.

A degraded nose seal means bad air bypassing the filters. The user breathes in fumes or particles without knowing it. The risk is real, even if the mask appears to be working normally.

Signs that indicate a replacement is necessary:

• The foam is permanently flattened or deformed
• Odors or fumes get through despite the mask being in place
• The foam shows traces of sweat, dirt, or visible deterioration
• The user feels unusual discomfort or pressure on the nose

Optrel recommends a visual check before each use and regular replacement according to the intensity of usage. In intensive welding, foam can wear out in a few weeks.

This pack of 5 nasal foams is the official replacement part for the SwissAir mask. It guarantees the maintenance of original performance: precise fit, correct seal, and preserved comfort.

At Dagobert Industrie, we only offer genuine Optrel parts. No generics, no approximate compatibility.

Optrel SwissAir mask maintenance: best practices to extend accessory life

A well-maintained mask is a mask that lasts. The nasal foam is one of the parts that wears out fastest because it is in direct contact with the skin during every welding session.

Inspect it regularly. If it is flattened, torn, or saturated with sweat, replace it without delay. Degraded foam compromises the seal of the Optrel SwissAir mask and reduces wear comfort.

To maximize the life of your accessories, adopt these simple habits:

• Clean the inner shell of the mask with a dry cloth after each use.
• Avoid solvent-based products that degrade the polyurethane foam.
• Store the mask away from heat and humidity.
• Replace the nasal foam at the first signs of wear, without waiting for complete failure.

At Dagobert Industrie, we recommend keeping a spare stock. A pack of 5 nasal foams ensures operational continuity without site interruptions.

This pack is designed exclusively for the Optrel SwissAir mask. Do not use generic foam: the dimensions and density are specific to this model, and an unsuitable part can alter the airflow and user protection.

FAQ - Nasal foam for Optrel SwissAir mask (x5)

1. What is the nasal foam of the Optrel SwissAir mask for?

The nasal foam is positioned between the mask and the face, at the nose. It improves the equipment's seal and increases comfort during long welding sessions.

2. When should the nasal foam be replaced?

Replace it as soon as it shows signs of wear: deformation, loss of elasticity, or poor adherence to the face. A degraded seal compromises the SwissAir mask's sealing and reduces the effectiveness of the powered ventilation.

3. Is this foam compatible with all Optrel SwissAir models?

This part is designed specifically for the Optrel SwissAir mask. It is not interchangeable with other Optrel ranges like the Panoramaxx or Crystal 2.0, which use different seal geometries.

4. How many nasal foams are included in this pack?

This pack contains 5 nasal foams. It is a practical quantity to anticipate replacements over time and avoid site interruptions due to a lack of available parts.

5. Do I need tools to replace the nasal foam?

No. Replacement is done by hand, without tools. The foam attaches by simple adhesion to the inner nasal part of the mask. The operation takes less than a minute.

6. Can I use a generic foam instead of this Optrel reference?

Technically possible, but not recommended. A non-approved foam may not offer the same certified seal or the correct geometry. At Dagobert Industrie, we only offer official Optrel replacement parts to guarantee the original performance of your equipment.
