Air pollution is very common both in the atmosphere and in the working environment. In order to avoid interruptions and provide good quality in production process, it is necessary to have clean air in working environment.
For this purpose TRAYAL Corporation developed a wide range of air purification filters.
Filters for Collective Protection
Filters for special purposes
Absolute FiltersFor fine air filtration the following absolute filters of efficiency classes F-6, 7, 8, 9 (SRPS EN 779) and H-10, 11, 12, 13, 14 (SRPS EN-1822) are used, such as:
- V4 Filters
- Dyader Filters
- Cellular Filters
- Frame Filters
- SC Filter Plates.
V4 filters are used for general aeration or as prefilters before absolute filters of higher class H-10 through H-14. The efficiency classes are F-6,7 and 8. These filters are made from plastic lateral sides, half-baths of Al profile, baths of galvanized sheet and filter paper of glass fibers of the appropriate class. The airtightness is achieved by means of polyurethane adhesive.
Dyader filters are intended for purification of air from aerosols, solids and liquid particles, germs,bacteria, viruses, spores and dust. They are manufactured in H-10 class (efficiency ≥ 95%) and H-13 class (efficiency ≥ 99,99%) against (DOP i NaCl) according to the SRPS EN 1822. These filters are made from galvanized sheet and filter paper of glass fibers of the appropriate class. The airtightness is achieved by means of polyurethane adhesive.
Cellular filters are intended for air filtration and conditioning in pharmaceutical industry, electronics, food industry etc. They are manufactured in H-10, 12, 13 efficiency classes (SRPS EN 1822).
Frame filters are intended for air filtration in pharmaceutical industry, medicine, computer technology etc. They are placed in water-proof frames and are manufactured in the following efficiency classes: H-10, H-13 and H-13(SC) which have been tested in regard to all parameters (SRPS EN 1822).
Filter plates SC are used for furnishing of facilities with laminated flux. They are manufactured in H-13 efficiency class (SRPS EN 1822).
FTP-100M FilterThese filters are intended to be fitted into the filter-ventilation device for the NBC protection of the M-84 tank. They provide protection of the crew and of devices against NBC aerosols, gases and vapours of Bot, against radioactive dust and other types of dust. The filter capacity is 100 m3/h of purified air.
The initial filter resistance: 1000±100 Pa at flow rate of 100 m3/h.
Airtightness: The filter is to be airtight at the pressure of 20 kPa.
The filter is to provide protective capacity against phosgene for at least 14 minutes at flow rate of 100 m3/h, protective capacity against phosgene is to be at least 12 minutes after exposure to vibrational stress and impact at flow rate of 100 m3/h.
Filters for Collective ProtectionTRAYAL Corporation manufactures collective protection filters, which are intended for protection of people and equipment in stationary facilities.
They are fitted into filter-ventilation systems of the facilities, especially in shelters. Depending on the shelter capacity and number of people, there are several types of filters: FKZ-63, FKZ-125 and FKZ-250. Depending on the type of connection, the above mentioned filters are available in three variants (A, B, and C).
Input: RD 110x1/4"
Output: RD 110x1/4"
Input: Flange Ø172 mm
Output: Flange Ø172 mm
Input: RD 110x1/4"
Output: Flange Ø172 mm
Filters for special purposesTRAYAL Corporation has developed different types of filters for air filtering according to special demands of buyers.
TRAYAL Corporation offers cylindrical filters of H-13 efficiency class (EN 1822), which are intended to furnish conditioners with laminated flux.
Adsorption filters are intended to purify air from acidic gases, organic vapours and solvents.
They are manufactured in standard dimensions or according to the requirements of the buyer.
PrefiltersFor the rough air filtration in hospitals, pharmaceutical industry, food industry, electronic industry and other industries, we offer the following:
- prefilter plates,
- filter tubes,
- prefilter bags,
- pocket filters.
Prefilter plates, tubes and bags are mainly manufactured at the buyer's demand. Pocket filters are manufactured in standard dimensions or on request. They are G-3, 4,F-5,V1 and V4 efficiency class according to SRPS EN 779.
Ventilation pipesFlexible ventilation tubes are used for the ventilation of mine underground rooms, industrial halls, tunnels, in shipbuilding and for other similar facilities where the reduction of emission of harmful substances is required, both from the stationary sources and from the movable sources –t contaminants of working environment.
They are made of the cured fabric rubberized on both sides using the technology of bonding segments by "cold" glueing. The cured and rubberized fabric is flame resistant and it has antistatic characteristics according to the 94/9 EC Directive.
Depending on the requirements of the buyer, the range of ventilation tubes being manufactured is as follows:
1. Flexible ventilation tubes without reinforcement (compression tubes) for supplying fresh air enriched with oxygen, and
2. Flexible ventilation tubes with reinforcement (depression tubes) for sucking out polluted air.
Dimensions of flexible ventilation tubes may vary depending on specific requirements of the buyer. The standard length is 5 meters and 10 meters, and standard diameters for compression tubes range from 200 mm, 30 mm..........to 1,200 mm, and for depression tubes from 200 mm, 30 mm..........to 800 mm. Depending on the diameter and design (compression tubes or depression tubes), the installation of ventilation tubes and of connecting elements is done as follows:
1. "Suspension" system by means of rubber bands fitted into the very tube, and
2. "Suspension" system by means of metal elements for hanging.
The method of connecting ventilation tubes is the following:
1. Elastic wire rings, whih make up a connecting system by slipping one tube over the other, are installed at the end of compression ventilation tubes and connecting elements of diameter Ø200 to Ø600mm.
2. Compression ventilation tubes and connecting elements of diameter higher than Ø600mm are connected by means of rubber belts.
3. Depression ventilation tubes are connected by by means of rubber/metal coupling.
