immediately.
1.5 Safety Warnings and Cautions
WARNING! RISK OF EXPLOSION!
The Unit is not explosion-proof rated. It can cause sparks and should
therefore not be used in areas with an explosion risk.
WARNING! Fire Hazard!
NeverusetheUnitforextractingand/orlteringinammable,glowing
or burning particles or solids or liquids.
NeverusetheUnitforextractingand/orlteringofaggressivefumes
(such as hydrochloric acid) or sharp particles.
WARNING!
Ozone (O3) is produced by the Unit. Ozone can be poisonous at low
concentrations.
Inhalation of ozone causes dryness of the mouth, coughing and
irritates the nose, throat, and chest.
Itmaycausedi󰀩cultyinbreathing,headachesandfatigue,and
could aggravate existing bronchial conditions including asthma.
The characteristic sharp, irritating odour is readily detectable at low

2. Product Overview
2.1 Intended Use
The Electrostatic Precipitator (ESP) models covered by this manual have been designed
primarily for ltering the extract air from commercial kitchens and have various specic
features to suit that purpose.
Note: Though they can also be used for air ltration in other commercial and industrial
applications where a high degree of ltration is needed, before considering
alternative uses, please check with the manufacturer to conrm that your Unit will
be suitable for its intended use.
CAUTION
No liability is accepted for damage or injury which results from
anyalternativeusewhichhasnotbeenveriedinwritingbythe
manufacturer.
Using the Unit for alternative uses not approved in writing by the
manufacturer is considered contrary to its intended use.
The Unit has been built in accordance with state-of-the-art standards and recognised
safety regulations.
Individual Units can be mounted together in various combinations to satisfy the
requirements of a particular installation.
CAUTION
Only use the Unit:
If it is not damaged in any way.
After following the instructions laid down in this manual.

Technical and Operations Manual - Product Overview8
2.2 Features
The following features are applicable to all four models covered by this manual:
●They can be installed outside without an additional weather housing.
The Unit’s casings is fully weatherproofed, with the Main Door components having
an IP Rating of 64 and the Door Assemblies themselves being tightly sealed to the
main chassis.
●The ionisation voltage runs at a negative potential which enhances both the
ionisation of particles and their consequent precipitation and the production of ozone
which helps eliminate odours in a kitchen environment.
● A high degree of e󰀩ciency, with power consumption between 20 Watts and 50
Watts, depending on the model.
●The Unit can be linked to a Building Management System (BMS) via a suitable
relay mounted on the DIN rail (See: Connecting the Unit to a Building Management
System on page 21).
● All internal components are designed for easy removal.
●The Mesh Filters (Pre and Post) are designed to drain independently and the
Collector Cell is designed to be e󰀩cient, robust and e󰀨ective.
●The Collector Cells and Filter Carriers can be easily removed for cleaning.
● The Collector Cells can be tted with ionisation wires or with stainless steel spiked
ioniser blades.
● All internal surfaces are as smooth and as free from screw and rivet heads as
practically possible to allow for ease of cleaning.
●Fully welded sumps prevent leakage of collected grease. The inward sloping edges
of the sumps encourage the ow of grease away from both the ducting and either
side of the Unit.
● The Door Assemblies are designed to allow the Unit to be quickly recongured for
di󰀨erent airow directions.
2.3 Operating Principles
Commercial kitchen exhaust pollution is composed of two distinct phases:
●The particulate phase; oil, smoke and grease particles.
●The gaseous or odour phase.
2.3.1 Oil, Smoke and Grease Filtration
The primary function of Puried Air’s range of Electrostatic Precipitators (ESPs) is to
e󰀨ectively lter the particulate phase (oil, smoke and grease) of extracted kitchen fumes.
The Unit covered by this manual utilises an ionisation process to lter particulates in the
exhaust down to a sub-micron level, with an e󰀩ciency of up to 98% when tted correctly.
The ESP Filters have been exclusively designed for ltering extracted kitchen fumes and
have integral sumps built in to collect the oil and grease particles. This not only simplies
servicing but eradicates potentially dangerous spillage from the bottom of the Unit.

Technical and Operations Manual - Product Overview 9
Electrostatic Precipitator (ESP)
Filter Unit
The entire range ts in-line with the kitchen’s ducting and the modular layout allows
additional Units to be easily added to cope with all kitchen fume extraction requirements.

Electrostatic Precipitator (ESP) - Operating Principles
Figure 4 (above) shows, in simple terms, how an electrostatic precipitator functions and
this is summarised below:
1. The air rst passes through a pre-lter.
2. The air then passes into the combined Collector Cell/Ioniser section where the
particulates in the air stream are charged to a negative potential.
3. The negatively ionised air then passes between the Collector Cell’s plates, which
are alternatively negatively charged or earthed.
4. The negatively charged particulates passing through the plates are then
simultaneously repelled away from the negatively charged plates and attracted to
the earthed plates, where they stick, e󰀨ectively ltering them from the airow.
5. The particulates remain on the plates or drain down in to the sump (hence the need
for regular cleaning).
6. The cleaned air exits through a post lter.

Filter Unit
Technical and Operations Manual - Product Overview10
2.3.2 Odour Control
Ozone is produced as a function of the charging of the Collector Cell’s plates in Puried
Air’s range of Electrostatic Precipitators. This helps to combat the gaseous or odour phase
of kitchen exhaust pollution.
However, for total control of the gaseous phase, Puried Air also manufactures and
distributes a range of Ultra Violet equipment and Ozone Generators as well as our Odour
Neutraliser, the ON100.
Note: We also supply a full range of passive ltration equipment, including Activated
Carbon, Ba󰀪e, Mesh, HEPA, Bag and Panel lters.
2.4 Electrostatic Precipitator Unit - Components
All models of Electrostatic Preciptator Unit comprise a Main Chassis with a number of
removable components, a Main Door and an Electrical Housing Door.
2.4.1 Main Chassis
The Main Chassis contains the removable Collector Cell, Filter Carrier, Pre and Post Mesh
Filters and non-removable, fully welded, Sump with Drain Plug.

3. Storage, Unpacking and Handling
3.1 Storage
Prior to installation, each ESP Filtration Unit must be stored in its original packaging in dry
conditions.
3.2 Shipping List
Each Unit is shipped with the following:
●ESP Filter components - Mesh Filters and Collector Cells.
●This Technical and Operations Manual.
3.3 Unpacking and Handling
Before installing:
1. Strip away all packaging, wrapping and strapping (this must only be done by trained,
professional installers).
2. Open the Unit and carefully remove all Mesh Filters and Collector Cells and place in
a safe and secure position, away from the installation area.
This operation will greatly reduce the weight of the Unit and allow much easier
installation.
3. Once the Unit have been successfully installed, carefully replace the Mesh lters
and Collector Cells, ready for commissioning.
WARNING!
The Unit is heavy and the appropriate lifting and handling practices
must be observed, for both unpacking and installation, to avoid
personal injury or damage to the equipment.
