E12 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.

5. RIGID POCKET 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 rigid pocket filters enclose a series of mini

from a fine grade media with sealed internal
spacer stitching to prevent pocket ballooning;
suitable for medium to fine grade applications
where a non-glass fibre element is preferred.
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.

HEPA FILTERS
Reliable source...

High Efficiency Particulate Air filters protect environments that
require ultra-clean air. Filtrex 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.
• Deep pleat, Mini pleat, V-pleat options
• 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 minipleat
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.

7. 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.”

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
• E-Pack carbon rigid pocket filter
• Filcarb 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 Filcarb system is efficient

AHU & VENTILATION SYSTEMS
ACTIVATED CARBON
FILTER SYSTEMS
11
Filtrex activated carbon filter systems are designed to suit many
different applications.
• At food factories, the strong smells emitted during the cooking
and processing of ingredients may require filtering before the
air is discharged into the atmosphere to prevent odours from
causing distress to the surrounding neighbours.
• Vent pipes from storage silos and effluent tanks often require
filtering to remove pungent fumes and vapours.
• In public buildings such as museums and libraries, incoming air
needs purifying removing gases that would have a deteriorating
effect on priceless manuscripts and artefacts.
• Airports and buildings in city areas such as offices, hospitals
and hotels, need effective filtering of air pollutants to ensure an
enhanced Indoor Air Quality (IAQ) level for the occupants.
We offer a wide range of air handling and ventilation systems from
bespoke design and installation, through to commissioning and
after-sales service.
The Exeon range of extraction systems are suitable for the removal
of fumes, vapours and dust and are available from small mobile
units to large centralized extraction systems. Along with this, we
offer a wide range of specialist units such as powder handling
booths, downflow benches and the E-Clean suction hood for
restoration and medical use.
“All round service has been excellent again, just continue with the
high standards that we expect.”

PLANT MAINTENANCE
DUCTWORK CLEANING & HYGIENE
SURVEYS, TESTING & REPORTING
12
Filtrex offers a complete plant maintenance service, including routine
assessments and offering upgrade advice and repairs to ensure your plant is
running as it should be.
There is often a case for upgrading filter types, improving frames and even
replacing major plant components such as air movement equipment. We
have the expertise and resource to measure performance, media types,
automatic cleaning systems etc and review filter performance and make
appropriate recommendations to achieve peak plant performance and make
energy savings where possible.
Contaminated ductwork systems can create an ideal environment for
microbiological growth, leading to the spread of bacteria. Filtrex offers
cleaning and decontamination of dust and debris from within ventilation
systems, and a deep clean of plant using our Filbac antibacterial cleaning
solution.
Grease in kitchen extract systems poses a serious fire risk. We provide a
complete cleaning and degreasing service for kitchen extract systems and
carry out fire damper inspections.
In LEV systems, dust build up in the ductwork leads to a reduction in air
volumes resulting in extraction levels dropping. It can also be a major fire
hazard, especially in ATEX classified zones. Filtrex carries out complete
LEV system cleaning to ensure your extraction systems are kept working
efficiently and safely.
As part of our cleaning and hygiene service, we also provide CCTV or
photographic surveys of ductwork systems and sample testing to give an
accurate report of the condition of your ductwork.
We offer a comprehensive range of air testing reports, to provide vital information
for those responsible for the air quality, such as IAQ tests, LEV surveys and HEPA
testing.
Our reports will help you to meet legislation, source and eradicate dust and fume
issues, and ensure your equipment is fully functioning to optimum efficiency. We
can look closely at how we can make energy savings through intelligent filter
selection.
Once a survey has been carried out by qualified engineers, we produce a report
advising you as to your obligations and make recommendations to assist you in
maintaining a healthy and productive workplace.

13. TRAINING & PLANT MANAGEMENT
FILTER SUPPLY & FIT
FILTRATION SERVICE RECORDS
13
The Filtration Service Record provides all the documentation
relating to the filters used on site, the change frequency and
cleaning records. This includes:
• Filter specification sheets
• Unit schedule
• Maintenance planner
• Service report sheets
• H & S documentation
Where regular maintenance and filter changing is carried out in-
house, we carry out a detailed site survey to ensure the correct
filters are being used. We produce a complete documentation and
record system for filter changing and unit servicing.
If required, we can train your on-site maintenance staff in
Compliance for Air Handling Units and Ventilation Systems.
Filtrex have successfully completed awareness training courses
for HTM03.01 Compliance for Air Handling Units and Ventilation
Systems Part A and Part B to provide crucial knowledge for
engineers with the responsibility of maintaining the plant.
For stretched maintenance teams, filter replacement is a job that can often
get put off. With filters needing to be ordered, deliveries received, filters
stored and then moved around site to the correct locations, filter replacement
can be a time consuming and labour intensive job.
With a detailed planner, showing when units are due for filter replacement, we
plan the whole change process by arranging the correct filters for the correct
units, meeting them up on site with our engineers who install the new filters
and take the old filters away for disposal. Filter change and unit condition
reports are produced, which are sent to site to be kept with the Filtration
Service Records.
