- FIT THE CONTOUR OF YOUR FACE
Range of extremely lightweight masks that fit perfectly to the face, without hindering the user. The compact profile of the body and filters allows all Elipse® range masks to perfectly seal to the face and ensure the greatest possible field of vision during use, without interfering with other eye or ear protections which users choose to wear. Elipse® come in 2 sizes.
- SOFT AND HYPO-ALLERGENIC
Unique comfort, thanks to the flexible and soft characteristics of the TPE (Thermo Plastic Elastomer), used in the Elipse® masks, making them very comfortable even for extended use. The materials that make up the mask are odourless and hypo-allergenic, “FDA” compatible, latex and silicone free. Conforms to ISO 109903-10:2010 skin irritation test of facemask.
- HESPA™ P3 FILTERS
High Efficiency Synthetic Particulate Air-filter is a technology used in all Elipse® range that enables the patented "encapsulation" production process. The 7 layers combined filter media is using exclusively mechanical filtration technology, giving the filter guarantee that the efficiency stay above 99,95% during the usage. Those filters are also water-repellent thanks to the nature of those media.
- PROTECTION AGAINST NANO PARTICULARES
GVS Elipse P3 particulate filters protect against nano particulates, and have been tested down to 40 nanometers (0.04 microns) still giving an efficiency of >99.95%.
GUIDE TO RESPIRATORY PROTECTION
Indications for the choice of respiratory protection devices are based on current knowledge. Before each use of the Elipse® respirator device, the buyer and user must ensure that the masks and filtersused are those specified for the type of pollutant and its concentrations.The ultimate responsibility concerning selection and use of products lies solely with the buyer and user.
- TYPES OF FILTRES
Dust filters are able to retain airborne particulates and are offered in various constructions, which enhance the filter’s characteristics with use of various types of filter material with different thickness, porosity and surfaces, to protect against particulates, gases and nuisance odours. Cartridge filters contain specific activated carbon, which retain certain gases and vapours by adsorption, while combined filters can remove both gases, vapours and particulates.
- TECHNICAL CHARACTERISTICS OF FILTERS
There are various types of particulate dust filters which have different filtration efficiency. Depending on which you choose, you can have the most suitable means of protection again environmental pollution conditions. The airborne particles are retained by the filter by means of mechanical and/or electrostatic action.
In the case of gas filters, substances are retained by the chemical -physical action of the activated carbon contained in the filter, able to adsorb and neutralise contaminants. It is assumed that the efficiency of gas and vapour interception on adsorbent material is 100%, atleast until the completion of the capacity of the filter material. For gas filters, we refer to ; time to completion or, rather, the period beyond which the filter is saturated and the pollutant begins to pass through the filter. This ‘breakthrough’ time depends on the quantity and quality of the adsorbent material used, on the active area of the cartridge, on its filtration capacity against the pollutant and on environmental concentrations and conditions.
Protection against particulate (dust, mists and toxic fumes)
DUST: dust forms when a solid material is broken down into tiny fragments.
The finer the dust, the higher the risk.
MISTS: mists are tiny droplets that are formed from liquid materials by atomisation and condensation processes, such as spray painting.
FUMES: fumes are formed when a solid material is vaporised by the high heat. The vapour cools quickly and condenses into very fine particles.
Respiratory filters have 3 classes of protection in EN143 with increasing efficiency, normally expressed with a Nominal Protection Factor (NPF) which is the ratio between concentration of the contaminant in the environment and inside the mask. The resulting factor indicates how many times the device can reduce the external concentration.
Classes of efficiency of dust respirators Minimum total filtration efficiency Max external concentration
Up to 4 x TLV
Up to 10 x TLV
Up to 40 x TLV
Anti-dust filters are distinguished by the colour WHITE.
Protection against gases and vapours
Gases and vapours are molecules so small that they penetrate particulate filters. You need to use a gas cartridge filterag ainst these.
The Elipse gas or combined gas and particulate respirators provide specific protection to the user by physical or chemical adsorption, withholding the harmful substances that are distinguished by identifying letters and colours:
TYPE PROTECTION CLASS
organic gases and vapours with a boiling point above 65°C 1,2,3 B inorganic gases and vapours (excluding carbon monoxide) 1,2,3 E sulphur dioxide and other acidic gases and vapours 1,2,3 K ammonia and organic ammonia derivatives 1,2,3 АX certain organic gases and vapours with a boiling point ≤ 65 °C. For single use only
There are different protection classes for each type of gas filter, depending on the amount of contaminants that the filter is able to adsorb. The choice is therefore determined by the predicted concentration of the pollutant:
Class Capacity Limit of use
Combined filters (gas and particulate), besides the colour of the specific gas/es, include a white band and their marking shows all the distinctive letters with their relative efficiency classes.
