SMARTPLEAT PLEATED PANEL
VENTILATION FILTERS
At a busy London hospital, after conducting extensive site surveys, we now supply filters by pre-arranged schedule, and deliver them the week before they are due to be fitted. For fast and efficient handling by hospital maintenance staff, we clearly label all filters and packaging for the individual plant rooms and AHUs where they are required.

V-FLOW COMPACT FILTERS
“We used to spend hours sorting through a massive filter delivery. Now they come in as and when we need them, and are fitted without disruption.”
Filtrex PVC framed V-Flow compact filters enclose a series of mini pleat glass fibre media packs, providing a large surface area with a much higher capacity than standard bag filters and excellent energy performance. For use in medium to fine grade applications with HEPA grade options available.
PROGUARD DUO BAG FILTER
A superior quality fibreglass bag filter with a pre-filter layter producing a much greater dust holding capacity. This in turn provides excellent energy saving potential as well as removing the need for a pre-filter in most applications.
Filtrex bag filters cover all applications and environments, from the low grade hi-loft synthetic type through to our highly engineered glass/synthetic dual layer filter.
• High loft synthetic – Grades G3 – M5• Synthetic fine grade media – Grades M5 – F9• Glass fibre – Grades M5 – F9• Metal, plastic & wood header options

High Efficiency Particulate Air filters protect environments that require ultra-clean air. Filtrex Arrestor HEPA filters are used for many applications: high grade industrial systems, clean rooms, hospitals, and electronic and pharmaceutical manufacturing, where contamination would be damaging and costly.
• Arrestor DP, Arrestor MP & Arrestor HC• Metal, wood or plastic frame• Gasket, gel or knife edge seal • Ceiling hood filter option• High temperature filter option• Grades E10 – E12, H13, H14, U15 – U17
For ease of handling and installation, our plastic framed Arrestor MP HEPA filter is a lightweight alternative to metal or wood framed options and is fully incinerable.
Housings can incorporate different filter combinations including panel, bag, rigid pocket and carbon. HEPA filters require specialist housings to ensure the standard of filtration is not compromised. We provide standard housings and safe-change types for critical applications where harmful contaminants may be present. These housings can be supplied complete with pressure loss gauges, DOP and pressure test points, shut off dampers and other accessories. Modular filter holding frames can hold both panel filters and filters with headers and are made from galvanised steel, stainless steel or aluminium.
When a large food manufacturer needed a reliable source for critical process related filter elements, we were able to supply the product they wanted on time and on budget and have been doing so ever since.

ACTIVATED CARBON FILTERS
“The best thing that FILTREX has done for us is produce and supply the filters that we require at short notice for equipment that we cannot afford to have out of line.”
ACTISORB CARBON CARTRIDGE SYSTEM
CARBON FILTERS
7
Activated carbon filters are used for the removal of molecular contaminants including odorous gases which are adsorbed into the microporous surface of the carbon granules.
Types of carbon filtration: • Bonded or granular carbon panels• Multi-cell units• V-Flow Carbon filter• Actisorb carbon cartridge system
A refillable cartridge system using steel mesh cartridges filled with granular activated carbon, mounted on a base plate via an easy change bayonet fitting. The Actisorb system is efficient and easy to maintain, achieving high air volumes and excellent removal of molecular contaminants and odorous gases.

FILTREX filter bags for dust control units and pneumatic transfer systems are available in a variety of media types to suit any application including a food safe certified option.
RETROFIT BAGS
CAGES & INSERTS
Cylindrical and pad type single sleeve cages and inserts for multipocket bags.
Retrofit pleated bag filter elements can replace bag filters in existing plants enabling higher air volumes and reduced pressure differentials, due to the increased surface area.
A reliable partner...
A large industrial company handling metal products needed a reliable partner to provide them with a complete LEV and filtration service, meeting health and safety standards and keeping plant running efficiently.

FILTRATION STANDARDS

WHAT IS ISO 16890?
ISO 16890 is the most recent international standard introduced towards the end of 2016 relating to the testing and classification of air filters. The new test results will be based on the filter’s ability to remove a range of particle sizes classified as: PM1, PM2,5 and PM10. There is a fourth classification, which is known as PM coarse, which is for filters that are less than 50% efficient at the PM10 particle size. Following the introduction of this new standard, the existing EN779: 2012 standard will be phased out over a period of time and replaced by ISO 16890.
WHAT IS PM?
PM stands for atmospheric Particulate Matter. The effects of PM on human health have been extensively studied over the years. The results are that fine dust can be a serious health hazard, contributing to or even causing respiratory and cardiovascular diseases. Different classes of particulate matter can be defined according to the particle size range. The most important ones are PM1, PM2,5 and PM10. The number signifies that the particulate range is for that particular micron diameter and smaller (down to 0.3 microns). For instance, PM1 is for particles of 1 micron and less, PM2,5 is measuring at 2.5 microns and less and PM10 is for 10 mirconrs or less.
PM1 is the smallest and most harmful airbourne particles. the NCBI concluded that PM1 may be more important for health effects than bigger size PM fractions. It was found to have greater effect on lung function parameters than the larger, PM2,5 fraction. For further information, please see the full article from NCBI https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5110587/
WHY HAS A NEW STANDARD BEEN INTRODUCED?
There has been interest from international trade and manufacturing for a well-defined, common method of testng and classifying air filters to enable maintenance personnel to choose the correct filter types they need.
Additionally, the current test standards have had known limitations by generating results which often are far away from realistic filter performance, i.e. overstating the particle removal efficiency of many products. With ISO 16890, a completely new approach for a classification system is adopted which gives better and more meaningful results.
ISO 16890 - GROUP CLASSIFICATION
According to new ISO standard, filters are divided into four groups: PM1, PM2,5 and PM10 and PM coarse.
A requirement for each group is that the filter captures at least 50% of the appropriate particle size range. for example, if a filter captures more than 50% of PM1 particles, it will be classified as an ISO ePM1 filter. The respective efficiency is then reported, rounded in 5% increments.
Alongside fine dust filters, the new ISO standard also evaluates coarse dust filters as ISO coarse. This refers to filters that capture less than 50% PM10.
CONCLUSION
Filtrex see the introduction of ISO 16890 as a positive move forward and will reinforce the work we currently undertake to improve indoor air quality for cleaner air and healthier lifestyles. It provides a more clear and transparent classification which
